Seattle Children’s Sports Physical Therapy

All of the Sports Physical Therapists at Seattle Children’s have specialized training in pediatric orthopedics and rehabilitation. Additional advanced training includes ankle, hip, and knee injuries, ACL rehabilitation, and return to play/sport testing. Therapists perform biomechanical analysis for upper extremity issues such as overhead sports and throwing, and for lower extremity, including video gait analysis for running and jumping. We treat spine issues such as spondylolisthesis, scoliosis, non-specific back pain, and cervical pain, as well as concussion, fractures, overuse injuries, and patients with pre- and post-operative care protocols. There are four therapists who are certified in the Schroth method for man-agement of idiopathic scoliosis. Three therapists are licensed athletic trainers, and six are APTA-board-certified clinical specialists in sports or orthopedics.

Speciality Clinics

ACL Class, Bellevue and South Clinics

The ACL class is designed for patients who have had an ACL reconstruction or other knee surgery. This is a 1 hour and 20 minute session with 4-5 kids. They are taken through a pro-gram involving warm-up, strengthening, plyometrics, functional training, endurance, core control, and stretching. The program is based on Sportsmetrics, which is an ACL injury prevention program. Participation in the ACL group helps kids rehabilitate their injured leg as well as working to reduce the chance of injury on the non-operative side. Once a patient is able to jog and do controlled jumping in their one-on-one PT sessions they can begin the group.

Athletes with Disabilities, All Clinics

We focus on helping school-age children and adolescents with disabilities heal after sports injuries or sports injury–related surgery. We work with athletes at any skill level who want to return to play, prevent injuries and improve overall performance.

Schroth Method for Scoliosis, Main Campus and Bellevue Clinic

The Schroth Method uses physical therapy to treat scoliosis. The goals of the Schroth Method are to prevent curve progression and improve posture through exercises based on the patient’s curve. The Schroth Method is not recommended for all patients with scoliosis. Patients must be at least 11 years old, have a cobb angle of 20 to 45 degrees, and be Risser 4 or lower.

Therapeutic Core Strengthening Class, Bellevue Clinic

The therapeutic core class is designed for patients with diagnosis of back and hip pain. This is a 55 minute class with maximum of 5 patients that is based in the Pilates method. The focus of this class is to improve core and glute strength and improve stability in a group setting. This may be appropriate for patients that do require formal 1:1 physical therapy as well as patients that are transitioning from physical therapy to the community as a stepping stone to discharge.

Video Initial Assessment

• Gold standard to treatment of athletic injury is: – Early detection

• To avoid muscle guarding and special test false negatives, evaluate injury right after it occurred

– The nature of the injury = mechanism – Degree of severity

08

Page 9: ACL Rehabilitation in Youth Sports - Seattle Children's · ACL Rehabilitation in Youth Sports 03 ... to being the Fitness Consultant for the Child Wellness Clinic, ... anterior cruciate

• Do a primary survey for life threatening conditions

• Ask yourself: – What is the level of injury – Do I need to activate EMS – Is the athlete able to get off field by themselves or

is assistance needed

• Airway/breathing • Consciousness • Severe bleeding • Position of limb • Athlete’s response to injury • Obvious deformity • Watch for signs or symptoms of shock • Remove athlete appropriately to the sideline for a

more thorough evaluation as needed = Secondary Survey

• History: – Chief complaint, mechanism of injury (MOI), unusual

sounds • Observation:

– Immediate swelling, deformity, willingness to move injured extremity

• Palpation: – Tenderness, pain

• Special Tests – Rule out Fx before performing special tests

• Application of skills

• Anterior Cruciate Ligament (ACL) Injury

Best Practices

• Ruptures occur in a position of max stress • Valgus stress,

lateral rotation with foot planted position and deceleration

• Sudden hyperextension with rotation

• Can be contact or non-contact

• Q-Angle – Angle femur enters hip

socket • Different landing

strategies – Females use less knee

and hip flexion during landing/jump to stop

– Causes an increase in quad activation and decrease in hamstring stressing the ACL

Predisposition and Factors

Lachman’s • Uniplanar

instability test Knee in 20-30o flexion (loose-packed position)

• Isolates ACL

• Anterior Drawer – Not as sensitive as Lachman’s due to knee flexion

angle – Increase knee flexion pulls open capsular and

ligamentous structures taut and positions hamstrings to oppose tibial translation

– May produce false negative – Normal translation is 4-6mm

• Lelli’s Lever Test • Make a fist and put

underneath the athlete’s tibia, inferior to the tibial tuberosity. With other hand apply a posterior force on quadriceps

• With intact ACL, the foot comes up off the table

• If the ACL is not functioning, the foot remains on the table6

Video Sideline Evaluation

• Patient Education – Athlete is an active participant in evaluation and

“game plan” – Answer questions – Prognosis: Short and long term

• Next 24 hours • What to expect • Who to call • ER or no? • R.I.C.E.

SPORT PSYCHOLOGY PRINCIPLES FOR REHAB & RETURN TO PLAY Julie Vieselmeyer, MS, MA Sport & Performance Psychology Consultant Seattle Pacific University

Agenda

Psychological impact of ACL injury

Psychological response & reactions to injury

Role of sport psychology

A biopsychosocial model

Protective & risk factors

Cognitive-behavioral interventions

A Case Study

Psychology of ACL Rehabilitation

Despite being physically recovered from ACL reconstruction 30-60% of athletes may not return to pre-injury participation level (Ardern, Osterberg, Tagesson, Gauffin, Webster, & Kvist, 2014)

ACL surgery has been found to have

many ramifications for psychological functioning (Brewer et al., 2007)

Psychology of Injury

The study of personal and situational factors, as well as cognitive, emotional, and behavioral responses of athletes to athletic injuries.

Psychological Response to Injury

Injury-relevant information processing Immediate negative consequences Attempts to understand how and why injury occurred

Emotional upheaval and reactive behavior Increased emotionality Denial Greatest need for social support

Positive outlook and coping Acceptance Adherence to treatment Feelings of hopefulness

Psychological Reactions: After Injury

Disappointment

Relief

Hopelessness

Dreams shattered

Isolation

Losing fitness

Pain

Performance decrements

Fear of treatment

Loss of motivation

Lack of confidence

Fear of re-injury

Identity loss

Grief

ACL Rehabilitation in Youth Sports 25

Page 26: ACL Rehabilitation in Youth Sports - Seattle Children's · ACL Rehabilitation in Youth Sports 03 ... to being the Fitness Consultant for the Child Wellness Clinic, ... anterior cruciate

Psychological Reactions: After Injury

All of the previous responses listed including anxiety and depression are actually NORMAL reactions to injury.

IF psychological reactions persist: TWO weeks or more Interferes with life

THEN a referral to a sport psychologist or mental health professional is needed.

Treatment Goals for ACL Injury

Reconstruction & Rehab Physical restoration Rehabilitation Return to play Increased strength & health Ability to participate in

lifelong sport

Sport Psychology Mental restoration and

wellbeing To increase adherence to

rehabilitation Psychological readiness to

return to play Increased resilience for

recovery and to prevent future injury

Ability to participate in lifelong sport is a source of enjoyment and satisfaction

What is Sport Psychology?

A tool for helping athletes see their sport from a different perspective with the goal of helping them reach their potential

Addresses clinical issues, performance enhancement, and life concerns in athletes

Sport Psychology Utilizes a Cognitive-Behavioral (CBT) Approach

A cognitive-behavioral approach considers how an individual’s thoughts, feelings, and behaviors interact to cause and maintain problems

Sport Psychology for Injured Athletes

Recent survey of 800 sports medicine docs indicated that 80% often discuss psychological/ emotional factors related to injury

Research with high risk athletes shows fewer injuries in those who complete stress management training (Weinberg & Gould, 2011)

Help athletes return to sport more quickly

Educate athlete about themselves and performance – provide tools to take attention away from maladaptive thoughts, emotions, and behaviors

Improves future performance

Biopsychosocial Model of Post-Sport Injury Response and Recovery

Risk Factors for ACL Rehab Cognitive

Low health & sport locus of control Low self-efficacy Catastrophizing

Affective Fear of reinjury Negative mood Pain High optimism

Behavioral Poor knee function Avoidance coping

Relational Low social support

Wierike, van der Sluis, van den Akker-Scheek, Elferink-Gemser, & Visscher, 2013)

Goals of Sport Psychology

Sport psychology strives to understand personal and situational factors, as well as cognitive, emotional, and behavioral responses of athletes to athletic injuries. The sport psychologist strives to select interventions and provide support to:

Increase protective factors

Decrease risk factors

ACL Rehabilitation in Youth Sports 27

Page 28: ACL Rehabilitation in Youth Sports - Seattle Children's · ACL Rehabilitation in Youth Sports 03 ... to being the Fitness Consultant for the Child Wellness Clinic, ... anterior cruciate

Cognitive-Behavioral Interventions

Coping skills training Mindfulness-based stress reduction Motivational Interviewing (MI) Acceptance-based interventions Emotion regulation Mental skills training Goal setting Relaxation Self-talk Imagery Routines

Motivational Interviewing (MI)

When injury occurs something has to CHANGE! Typically injury is not a welcome change but that’s

not always the case MI is an intervention or a “way of being with people” to facilitate change Fundamental tenets: Collaboration Evocation Autonomy

Motivational Interviewing (MI)

How does MI look in practice?

(1) Empathy

(2) Develop Discrepancy

(3) Roll with Resistance

(4) Support Self-Efficacy

Goal Setting

Build a strategic plan to achieve a desired result.

LAW OF THE LADDER

LAW OF THE HARVEST

Goal Setting

Builds motivation Being goal oriented promotes a positive attitude Promotes adherence to rehabilitation plan Ensures athlete and treatment team have matching expectations: Set date for return to play Establish concrete plan for home program Determine other areas for improvement: sleep, nutrition,

mental skills

Note: Treatment team should emphasize the importance of sticking to the plan and not doing more even when athlete feels stronger

Self-talk

Refers to our internal dialogue. Many benefits to positive talk!

Enhances concentration

Improves confidence

Builds self-efficacy

Reinforces success

Use cue words to trigger effectiveness Ex: “breathe” or “engage core - lift”

Use affirmations to improve self-efficacy “I am doing everything possible to get better.”

“I have a great team supporting me.” “I can do this!”

Relaxation

Being relaxed is an important state for body and mind to function optimally. Many benefits of relaxation for rehab and sport.

Decreases body tension

Improves coordination

Improves body awareness

Increased energy management

Improves ability to focus

Increases composure

Facilitates rest and recovery

Relaxation

Deep breathing

Progression Muscle Relaxation (PMR)

Routines

Focus is on “doing” Routine behavior aids in minimizing negative thoughts or emotions Effective routines incorporate physical and mental skills

Why routines work?

A Case Study: Hannah

Hannah is 21 year old collegiate soccer player Presenting problem Right ACL reconstruction during her senior year of

high school Left ACL reconstruction during the first game of her

sophomore year of college Physical and psychological challenges in her sport,

school, and relationships as well as in changes in self-esteem and identity as a result of her injuries

Hannah wants to regain her past level of play for her senior year of college and regain enjoyment in her sport.

A Case Study: Hannah

Cognition “Am I ever going to play

again?” “What if I can’t achieve my

goals?” “What do others think of me?”

Affect Symptoms of anxiety and

depression Fear of reinjury Decrease in self-efficacy Reduced motivation

Behavior Sleep difficulties Change in appetite Avoidance of team

activities

Relationally Problems with teammates

and coach Problems with friends and

significant others

Treatment & Prognosis

Counseling Journaling Modeling Mental Skills Goal setting

Relaxation Imagery

Self-talk

Key Take-Aways

Following injury there is a typical pattern of response and psychological reactions but how athletes progress through these stages can vary widely

Identify coping problems early in rehabilitation and assess for psychological difficulties even after physical healing has occurred

Psychological functioning during rehabilitation predicts return to play and may impact future health and fitness

Utilize a biopsychosocial model to develop interventions such as motivational interviewing (MI), mindfulness based stress reduction, and mental skills training

Sport psychology interventions can help athletes return to sport, increase speed of recovery, reduce susceptibility to future injury as well as face adversity in future situations

Youth ACL injuries

Gregory A. Schmale, MD Seattle Children’s Hospital

Seattle, Washington

Youth ACL Injuries are on the rise

• Increasing awareness – Increased reporting – Increased incidence

Treatment philosophies Protect the physis No surgery until mature

Reconstruct, but avoid the physis

intra/extra-articular procedure all epiphyseal reconstruction

Risk the physis and reconstruct More anatomic reconstruction Protect the knee

Observation Woods, 2004: “No evidence that intentionally delayed

anterior cruciate ligament reconstruction increased the rate of additional knee injuries.”

Risk of further injury – • Graf,1992: 8/12 skeletally immature patients with ACL tears returned

to sports with a brace after quad and HS rehabilitation. • After return to sports, all braced patients developed instability with

multiple episodes of "giving way,” by a mean of 7 months. • 7 patients sustained further meniscal damage an average of 15 months

(range 7-27 months) after initial injury.

• Brace management did not prevent instability or new meniscal tears.

Observation Mizuta, 1995

Conservative treatment for complete tears of the ACL in 18 skeletally immature patients, min 36 months f/u

Lysholm knee mean score of 64.3. Only one patient had returned to her pre-injury level of athletics. Secondary meniscal tears in 6 patients, and 3 more had the clinical

signs of a tear at follow-up. Radiological evidence of degenerative changes was found in 11 of the 18 patients.

The results of non-operative treatment for ACL injuries in this age group are poor and not acceptable.

- Lawrence, 2011: Patients < 14 yo who underwent surgical reconstruction of an acute ACL tear >12 weeks after the injury:

• Had a significant increase in irreparable medial meniscal tears and lateral compartment chondral injuries at the time of reconstruction.

• When a subjective sense of knee instability was present, this association was even stronger.

Questions Do growth abnormalities occur with transphyseal

reconstructions?

What is the reinjury rate and rate of further surgery after ACL reconstruction in youth undergoing a transphyseal ACL reconstruction?

How do satisfaction and function correlate with return to prior level of sports after ACL reconstruction in youth?

What factors contribute to failure to return to pre-injury activity levels?

No relationship between function and activity Patients who were less active indicated a change in interest with advancing age

Summary

ACL tears are common in youth.

Rehab and bracing programs may not prevent further injury in patients with an ACL deficient knee.

Rehab after surgery may not return the athlete to their pre-injury activity level.

Summary

Hamstring autograft is our go-to ACL graft.

Transphyseal reconstructions deserve careful monitoring of post-op growth.

The surgery is straightforward; the rehab, challenging.

Controversies With regards to bracing, there are few facts:

No known study shows a knee with a torn ACL does better with a brace than without, with regards to further activity.

No known study shows post-op bracing after ACL reconstruction is advantageous and prevents re-tear. Repeated studies have shown that there is no advantage to post-op bracing.

However, hyperflexible patients are 1) more likely to tear their ACL’s in the first place, and

2) are more likely to re-tear after a reconstruction.

Hence, I brace these patients to avoid the position of hyperextension, a position that might put them at risk for further injury.

Objectives

• Determine ACL injury risk factors • Understand principles of ACL injury prevention • Identify and understand copers vs noncopers • Understand principles of ACL reconstruction (ACLR)

“prehabilitation” • Understand principles of ACLR rehabilitation (early,

intermediate, and late phases) • Identify special considerations based on surgical

procedure and concomitant injuries

2

ACL Injury Risk Factors

3

Non-Modifiable Factors

• Gender • Females have two to six times greater ACL injury rate1

• No gender differences in ACL injury rates before onset of puberty2

• Anatomy

• Height3

• Femoral notch width3,4 • Q-angle3,4

• Joint laxity5 – Knee hyperextension increases the odds of an

ACL injury fivefold in young female athletes6

4

Modifiable Factors

• ACL injury occurs within 30-100 ms of initial contact during landing, deceleration, and/or lateral pivoting maneuvers7,8

• Biomechanical impairments leading to ACL injury: • Decreased knee, hip, and trunk flexion8,9,10 • Knee valgus8,9,11 • Hip and knee internal rotation8,9,10,11 • Anterior tibial shear10,11

5

Modifiable Factors (cont.)

• Neuromuscular deficits leading to ACL injury

• Female athletes often lack “Neuromuscular spurt” 12,13

• Decreased lower extremity force attenuation during landing14

• Decreased hamstrings to quadriceps torque ratios15

• Altered hip musculature recruitment16

• Proprioception deficits in trunk control17

Prediction Algorithm for Female Athletes at High Risk for ACL Injury

• Measurements of knee valgus and knee flexion ROM during drop vertical jump, as well as body mass, tibia length, and quadriceps-to-hamstrings strength ratio predict high knee abduction moment in female athletes which has been linked to increased risk of ACL injuries19

• Predicts high knee abduction moment with 84% sensitivity and 67% specificity in female athletes19

Figure 919

14

The Landing Error Scoring System (LESS)

• The LESS utilizes video analysis of a drop vertical jump task. Shown to be valid and reliable for identifying high risk movement patterns10

• No relationship between risk of ACL injury and LESS score in male and female high school and collegiate athletes20

Figure 110 15

Drop Vertical Jump Predicts ACL Injuries

• Increased knee abduction during landing of drop vertical jump predict ACL injury with 78% sensitivity and 73% specificity for teenage female athletes21

Figure 425

• Physical therapists can identify high knee valgus angles during a drop vertical jump using real time observation22

16

Trunk Control Predicts Potential Knee Injuries

• Deficits in active trunk repositioning predict knee injury status with 90% sensitivity and 56% specificity in collegiate female athletes17

17

Tuck Jump Assessment • Tuck jump assessment tool may be useful in assessing

and training high risk movements23

Appendix 118

ACL Rehabilitation in Youth Sports 45

Page 46: ACL Rehabilitation in Youth Sports - Seattle Children's · ACL Rehabilitation in Youth Sports 03 ... to being the Fitness Consultant for the Child Wellness Clinic, ... anterior cruciate

Predicting Potential ACL Injuries

• Females with low hamstrings strength and similar quadriceps strength relative to male controls may be at increased risk for ACL injury24

• Decreased hamstrings strength correlated to increased knee valgus during double and single leg leap landing in adolescent females resulting in increased loading at ACL25

19

Predicting Potential ACL Injuries (cont.)

• Isometric hip abduction and external rotation (ER) strength measures are able to predict noncontact ACL injury in male and female athletes26 • Cutoff for athletes at high injury risk: hip ER ≤ 20.3% of

body weight, hip abduction ≤ 35.4% of body weight26

20

Principles of ACL Injury Prevention

21

Training Strategies for ACL Injury Prevention

• Meta-analysis suggests that neuromuscular training and

education interventions decrease the incidence rate of ACL injury by approximately 50%27

• Plyometric training with biomechanical analysis and training appears to be key in reducing ACL injury rates28

22

Training Strategies for ACL Injury Prevention (cont.)

• Neuromuscular training programs that include

biomechanical, proprioceptive, and strength training have shown:

• Positive performance enhancements – improved strength and

power28,29,30,31,32

• Improved biomechanics and coordination leading to decreased ACL injury risk28,29,30

23 Table 118 24

46

Page 47: ACL Rehabilitation in Youth Sports - Seattle Children's · ACL Rehabilitation in Youth Sports 03 ... to being the Fitness Consultant for the Child Wellness Clinic, ... anterior cruciate

Training Strategies for ACL Injury Prevention (cont.)

• Feedback with external focus of attention (focus on

movement effect not the movements themselves) may be more suitable for acquiring complex motor skills33

• Improved movement patterns found when using external focus of attention: • Greater knee flexion angles34 • Lower peak vertical ground reaction force35 • Improved neuromuscular coordination36

25

Figure 1 and 237

Feedback with External Focus of Attention

26

Timing of ACL Injury Prevention

• Systematic review of ACL injury prevention programs38 showed success with: • At least 6 weeks of preseason training 2-3 times per week • In-season training 1-2 times per week • focus on strength, plyometrics, balance, proprioception, and

education/feedback on proper technique

• Both high intensity preseason neuromuscular training

and medium intensity (warm up) in-season training have demonstrated decreased ACL injury risks28

27

Timing of ACL Injury Prevention (cont.)

• Preadolescence or early puberty seems to be a critical phase related to increase ACL injury risk in female athletes39

• Neuromuscular training programs may help to decrease the gender differences in biomechanical control and decrease adolescent female athlete ACL injury risk1

28

ACL Injury Prevention Programs

• Sportsmeterics • Training program including flexibility, plyometric, and strength

training shows significant decrease in non-contact knee injuries for high school female athletes29

• Santa Monica Prevent Injury and Enhance Performance (PEP) Program • Training program including education, strengthening, stretching,

plyometrics, and agility training showed decreased ACL injuries in female division I soccer players40,41

29

ACL Injury Prevention Programs (cont.)

• Knee Injury Prevention Program (KIPP) • Coach-led 20 minute neuromuscular warm up focusing on

strength, balance, plyometrics, agility, and education to avoid dynamic knee valgus showed significant reduction in noncontact lower extremity injuries for girls high school basketball and soccer42

• FIFA 11+ • Warm up including strengthening, education, and neuromuscular

training showed a trend toward lower extremity injury risk reduction in youth female soccer players, although not significant43

ACL Injury Prevention Programs (cont.)

• A systematic review44 found that the only programs to significantly reduce ACL injuries in adolescent female athletes were:

• Sportsmetrics

• Prevent Injury and Enhance Performance (PEP) Program

• Knee Injury Prevention Program (KIPP)

Copers and Noncopers Following ACL Injury

33

Copers vs. Noncopers

• Copers: • Able to resume all preinjury activities without episodes of giving

way and do not require surgery • Perform significantly better than noncopers on all four single leg

hop tests45

• Noncopers • Unable to return to previous level of activity or experience

episodes of giving way • Demonstrate worse gait kinematics and time-distance variables

when compared to copers at 4 months post injury, noncopers utilize a joint stiffening strategy46

34

Copers vs. Noncopers (cont.)

• Hurd et al 200847 • 832 highly active individuals with subacute ACL tears were

followed over 10 years • Screening exam around 6 weeks after injury determined

potential copers (146/345) and noncopers (199/345) • 6 meter timed hop at least 80% • Knee Outcome Survey ADL scale at least 80% • Global rating of knee function of at least 60 • No more than one episode of giving way

• 25 out of 63 (39%) of the individuals who passed all components of rehabilitation and the return to sports test did not undergo ACLR

• 89% (308/345) of the initial group eventually had surgery, only 7% (25/345) did not

35

Copers vs. Noncopers (cont.)

• Ramski et al 201348

• Meta analysis of operative vs nonoperative treatment of child and adolescent ACL tears favors early surgical stabilization over nonoperative or delayed treatment

• Nonoperative or delayed treatment patients were 33.7 times more likely to have clinical instability or pathological laxity

• Risk of meniscal tear after operative treatment was 4%, risk after nonoperative treatment was 67%

• Significantly greater rate of return to activity, 92% with operative treatment, 43.75% with nonoperative treatment

36

48

Page 49: ACL Rehabilitation in Youth Sports - Seattle Children's · ACL Rehabilitation in Youth Sports 03 ... to being the Fitness Consultant for the Child Wellness Clinic, ... anterior cruciate

Copers vs. Noncopers (cont.)

• Surgical repair appears to be the preferred treatment for individuals who choose to return to high level pivoting sports49

• Early onset knee osteoarthritis (OA) is a risk after ACL injury with

or without surgical intervention50,51

• 70% reduction in high risk sports participation for those treated conservatively, only 44% reduction for those treated surgically at 10-13 year follow up52

37

Principles of “Prehabilitation”

• Reduce inflammation

• Restore normal range of motion – decreased risk of post-op arthrofibrosis with normalized AROM prior to surgery54

• Restore neuromuscular control – normalize gait pattern

• Prepare patient for surgery

38

Principles of “Prehabilitation” (cont.)

• Prevent muscle weakness • Pre-op quadriceps strength has significant impact on long term

knee functional outcomes following ACLR55,56 • Quadriceps strength within 20% of uninvolved leg recommended

prior to surgery55

• A progressive 5 week exercise therapy program has shown significant improvement in knee function following ACL injury57

39

Anatomy and Physiology of ACL Reconstruction (ACLR)

40

• Incorporation of graft at insertion site: • Bone autograft (patellar tendon) between 6-8 weeks58 • Soft tissue autograft (hamstring or quad tendon) between 8-12

weeks59 • Allografts between 4-6 months60

• Graft strength:

Table 361

41

Ligamentization

• Graft weakens during first 2-4 weeks, then begins progressive revascularization and maturation62,63

• Resembles a native ACL by 1 year62

Rehabilitation following ACL Reconstruction (ACLR)

43

Principles of Early ACLR Rehabilitation

• Goals of immediate post-op phase (~0-3 weeks) • Restore full passive knee extension • Progress knee flexion ROM • Reduce post-op inflammation and pain • Progress toward ambulation without assistive device • Re-establish voluntary quadriceps control • Protect reconstructed ACL and donor site

44

Early ACLR Rehabilitation (cont.)

• Restore full passive knee extension ROM • Patients who get and maintain full knee motion show decreased

prevalence of OA long term after ACLR65 • Loss of 3-5° knee extension compared to uninvolved knee had

worse subjective and objective outcomes a mean of 14.1 years post ACLR66

• Progress knee flexion ROM • Immediate motion is critical to avoid ROM complications67 • No significant difference for continuous passive motion and

standard treatment vs standard treatment alone on knee ROM and joint laxity68

45

Early ACLR Rehabilitation (cont.)

• Reduce post-op inflammation and pain • Reduced effusion leads to increased ROM, decreased pain, and

improved function53 • Pain may play a role in quadriceps inhibition69 • Debate exists on joint effusions role in quadriceps inhibition56,70,71

• Progress toward ambulation without assistive device • Weight-bearing as tolerated • No significant benefits of bracing72 • Possible benefit of locked brace immediately post-op due to

quadriceps inhibition

46

Quadriceps Inhibition 1 Week Post-Op

47

Early ACLR Rehabilitation (cont.)

• Re-establish voluntary quadriceps control • Inhibition of quadriceps is common initially after ACLR and can

persist long term74 • Weakness due to arthrogenic muscle inhibition and muscle

atrophy53 • Neuromuscular electrical stimulation (NMES) combined with

exercise was more efficient than exercise alone at increasing quadriceps strength75

• Open and closed chain exercises are as effective as each other for knee laxity, pain and function in short term after ACLR68

Straight Leg Raise with Mild Quadriceps Lag

49

Early ACLR Rehabilitation (cont.)

• Protect reconstructed ACL • Seated knee extension between 10°-50° knee flexion loads the

ACL significantly more than weight bearing exercises73 • Facilitate hamstrings co-contraction: forward trunk tilt (30-40°),

heels on ground, knees over feet (sagittal plane), knees not moving more than 8-10 cm anterior to toes73,76,77

• Protect donor site • Potential for hamstring tendon regrowth following ACLR78,

consider delaying resistive hamstrings exercises 8 weeks61 • Donor site morbidity can occur with patellar tendon graft79, be

aware of patellar tendon pain

Principles of Intermediate ACLR Rehabilitation

• Goals of intermediate post-op phase (~3-12 weeks) • Restore full ROM • Progress quadriceps strength and control • Restore neuromuscular control and balance • Gradually increase loading at knee

53

Intermediate ACLR Rehabilitation (cont.)

• Restore full ROM – full knee ROM compared to uninvolved limb results in decreased risk of OA long term65

• Progress quadriceps strength and control • Initial focus on closed chain terminal knee extension control • Squat80 and lunge81 show minimal to no ACL loading, LAQ

against resistance increases ACL load82 (still less than walking83) • Progress eccentric loading84

Intermediate ACLR Rehabilitation (cont.)

• Gradually increase loading at knee (cont.) • Progress from sagittal plane to multi-planar movements

• Persistent swelling or pain indicate over aggressive treatment61 • Introduce jogging in pool at 2 months • Progress hamstrings strength following hamstring autograft

• Hamstring tendons have the ability to regenerate following autograft78

• The use of hamstring autograft does not limit recovery of hamstrings strength94

• Prepare for late phase plyometrics – practice good habits!

61

Hamstrings Deficits Following ACLR

62

Principles of Late ACLR Rehabilitation

• Goals of Late post-op phase (~3-9 months) • Progress neuromuscular control • Normalize quadriceps and hamstrings strength • Introduce plyometric activities • Progress to sport specific training • Prepare for return to sport

• Seattle Children’s ACL group class

63

Late ACLR Rehabilitation (cont.)

• Progress neuromuscular control

• Biomechanical factors predict second ACL injury risk, 92% sensitivity, 88% specificity86:

• A net internal rotation moment of the uninvolved hip with landing drop vertical jump

• Increased frontal plane knee motion during landing drop vertical jump

• Sagittal plane knee moment asymmetries at initial contact on drop vertical jump

• Deficits in single leg postural stability

• Neuromuscular control deficiencies are the only known modifiable factors predictive of second ACL injury risk86

64

Neuromuscular Impairments Leading to Secondary ACL Injury Risk

Figure 586

65

Late ACLR Rehabilitation (cont.)

• Normalize quadriceps and hamstrings strength • Recommended that prior to return to sports:

• quadriceps strength at least 85% of uninvolved leg30 • hamstrings:quadriceps strength ratio >66% for males, >75% for

females61 • Deficits in neuromuscular coordination of hamstrings and quads

following ACLR may manifest as excessive landing contact noise95

Late ACLR Rehabilitation (cont.)

• Introduce plyometric activities

• Recommended that prior to initiating late phase rehab:85 • Full pain free AROM • Minimal to no joint effusion • At least 70% strength symmetry

• Neuromuscular training including plyometric and strength training can improve speed, strength, and power while decreasing injury risk in teenage females96

• Control of dynamic knee valgus improves with plyometric training30

67

Biomechanical Flaws with Jumps

68

Late ACLR Rehabilitation (cont.)

• Introduce plyometric activities (cont.)

• Alterations in force-attenuation and generation as well as multi-planar asymmetries at hips and knees noted up to 2 years after ACLR in males and females97,98

• Altered hip and knee biomechanics found on the involved limb following ACLR even though single leg hop test distance was within 93% of uninvolved limb99

• Altered trunk control during running found in females post-ACLR compared to matched controls100

69

Lunge Jumps

70

Late ACLR Rehabilitation (cont.)

• Progress sport specific training

• Return to running program initiated at 3 months at our clinics • Debate exists on when to return to running85,61 • Keep in mind graft incorporation time frames

• Addition of on field rehabilitation may help to address deficits in return to sport101,102

• Female athletes who had returned to sport following ACLR showed significantly higher knee valgus during 45° cutting task compared to uninjured controls103

71

Late ACLR Rehabilitation (cont.)

• Prepare for return to sport

• Return to sport assessment – 6 months post-ACLR at our clinics followed by gradual return to sports

• Single leg hop tests at 6 months post-ACLR demonstrate excellent accuracy for prediction of athletes with normal knee function at 1 year post-op104

• Within the first year post-ACLR 2/3 of athletes had not returned to their competitive sport105

• Individuals with very high preinjury activity level have a higher probability of not returning, due in part to fear of reinjury106

72

Seattle Children’s ACL Group Class

• Group treatment session • 80 minute weekly sessions with intensive plyometric,

strength, endurance, and agility training • Patients eligible once they are at least 3.5 months post-

op and: • Perform single leg squat to at least 60 degrees with good form • Able to jog for 5 minutes with proper gait • No reported feelings of instability

• Progressing toward return to sports assessment at 6 months

73

Seattle Children’s ACL Group Class (cont.) • Dynamic warm up • Jump training

• Focus on proper biomechanics and correcting “high risk” movements

• Progress from DL SL, stationary multi-planar, increasing speed

• Strength and stability training • Focus on quadriceps, hips, and hamstrings strengthening • Focus on proper biomechanics

• Agility training • Progressing from sagittal plane multi-planar • Sport specific agility activities

• Cardiovascular endurance training • Core strengthening • Flexibility training

74

Special Considerations for ACLR

75

ACLR Using Allograft

• Morphology, maturation, and ligamentization of autograft is favorable to allograft at 3 and 6 months post-op107

• Meta-analysis of patellar tendon autograft vs allograft showed increased graft failure and decreased performance on single leg hop test for allograft108

• A slower progression to athletic activities is advised.61 Due to delayed graft incorporation (4-6 months)

76

ACLR With Meniscal Pathology

• Meniscal repairs performed at the time of ACLR have superior healing rates and better outcomes than isolated repairs109

• Immediate weight bearing and mobilization recommended84

• Limit deep knee flexion in weight bearing (specific guidelines based on location and extent of repair), no squatting past 60° for 8-12 weeks61

77

ACLR With Collateral Ligament Injury

• Medial Collateral Ligament (MCL) Injury • Grade I and II MCL sprains may not require surgical intervention • ACL with concomitant MCL injuries often present with excessive

scar tissue formation and may require an accelerated progression for ROM110

• Lateral Collateral Ligament (LCL) Injury

• Combined ACL and LCL injuries are relatively rare, 1% incidence111

• Avoid excessive varus stress at knee, as well as, isolated hamstrings strengthening up to 6-8 weeks61

78

ACLR With Articular Cartilage Lesions

• Occur in approximately 71%-85% of traumatic ACL injuries112,113, most commonly on lateral femoral condyle and lateral tibial plateau114

• Progress partial to full weight bearing and gentle ROM to assist articular cartilage healing61 • Avoid excessive compressive force early in rehab115 • Full unloading and immobilization may be harmful to healing

articular cartilage115

• Surgical articular cartilage repair will impact rehabilitation progression depending on size and location of repair

79

Take Home Messages

80

Take Home Messages

• Look for modifiable ACL injury risk factors in all patients • Decreased hip and knee flexion, knee valgus, heavy landings

with jumping tasks, and poor trunk control

• Neuromuscular training may help decrease the risk of ACL injuries and enhance athletic performance if: • Comprehensive training programs include plyometric, balance,

strengthening exercises, and education/feedback on technique • They are performed 2-3 times per week for at least 6 weeks at

high intensity

81

Take Home Messages (cont.)

• Adolescent athletes who desire to return to a high level of sport participation have the best success with surgical ACLR

• “Prehabilitation” to normalize knee ROM and quad strength has significant benefit for post-op outcomes

• Incorporation times of ACL graft: • Bone autograft (patellar tendon) between 6-8 weeks • Soft tissue autograft (hamstring or quad tendon) between 8-12

weeks • Allografts between 4-6 months

82

Take Home Messages (cont.)

• In early post-op phase: • Get full knee extension and regain voluntary quad control

especially in terminal knee extension • Protect ACL graft by avoiding open chain knee extension

between 10°-50° • Safe to incorporate closed chain strengthening early

• In late post-op phase: • Biomechanical factors that predict second ACL injury risk during

drop vertical jump: • hip internal rotation on uninvolved limb, knee valgus, asymmetrical

knee flexion at initial contact; as well as deficits in single leg postural stability
