Objectives
At the conclusion of this presentation the participant will be able to:
• Discuss common arthroscopic techniques for intraarticular hip pathology.
• Discuss post-operative intervention programs after hip arthroscopy.
• Discuss the latest evidence on risk factors and suggested strategies for reducing future pathology.
• Discuss emerging diagnoses classified as external hip impingement.
Types of FAI Progression of Hip Labral Pathology
Excessive loading of the labrum (FAI)
Fraying of the articular margin of the anterior
labrum
Tearing along the articular margin of the
anterior labrum
Delamination of the articular cartilage from
the articular margin adjacent to the labral
lesion
Global labral and articular cartilage
degeneration

Systematic Reviews Level of Evidence
• Cheatham et al. 2014
– Level 4 evidence (N=6)
– Included only research that measured post-operative rehabilitation
– Found 20 clinical commentaries on post-operative rehabilitation
• Grysbowski et al. 2015
– Level 1 evidence (N=1)
– Level 3 evidence (N=2)
– Level 4 evidence (N=15)
– Included research that reported post-operative rehabilitation
Systematic Review
• Summary– A paucity of evidence exists regarding post-operative
rehabilitation after hip arthroscopy. Most of the literature comes from:• Case reports/series (level 4 evidence)
• Clinical commentaries (level 5 evidence)
– A consensus on the best program has yet to be determined.
– The existing evidence suggests that a 4 to 5 stage program with an initial period of weight-bearing and mobility precautions is efficacious in regard to function, patient satisfaction, and return to competitive level athletics.

Case Report 2012
• Cheatham SW, Kolber MJ. Rehabilitation after Hip Arthroscopy and Labral Repair in a High School Football Athlete. Int J Sports Phys Ther. 2012 April; 7(2): 173–184.
Case History
• Patient: – 18- year-old senior male high school athlete – 210 lbs. with muscular build and excess body fat
• Mechanism: – Insidious onset of deep “anterior groin pain” for one year prior to diagnosis. – Intermittent “groin” pain during and after physical activity which eventually
became more severe.
• Diagnosis: – Left mixed cam-pincer femoroacetabular impingement with an anterosuperior
labral tear.– Confirmed by MRA
• Surgical Intervention: – Acetabular and femoral head osteoplasty & chondroplasty, capsular
synovectomy, plication, and an anterior superior labral repair.
• Post-Surgical Orders: Evaluate and treat with crutch ambulation (WBAT)
*Please see publication for more details
Mixed Impingement
• Combined. Combined impingement just means that both the pincer and cam types are present.
Assessment
• Pain: – (4-5/10) with left hip flexion/adduction
• Posture & Gait: – Compensatory right trunk shift in an effort to unload the affected
left limb in standing and gait ambulation with crutches.
• ROM:– Decreased left hip ROM in all planes due to pain and
“apprehension” by the patient.
• Strength & Muscle Length: – General weakness (3/5) and decreased length of the left hip
musculature (rectus femoris, hamstrings, abductors/ITB)
• Palpation:
– Tenderness in the anterior hip musculature.
• Pelvic and LE Neurovascular Screen: (-) for medical “red flags”

Phase I: Manual Therapy
Circumduction• Beck (2008) found adhesion
formation between the joint capsule and the resected femoral neck which may lead to soft tissue impingement by squeezing the acetabular labrum during hip flexion and internal rotation.

– Home Program: Continued maintenance exercises by patient
Post-Surgical Rehabilitation Pearls
• Phase I: – Try and avoid intra-articular adhesions and Iliopsoas
irritation. Gain early hip strength and neuromuscular control.
• Phase II-III: – Monitor deep hip flexion and motions of impingement.
Restore myofascial restrictions of hip musculature. Add additional abdominal core exercises.
• Phase IV: – SL multi-direction hip control should one criteria for return
to activity. Restore total body conditioning.
• * Special Testing: – Should be included in each phase as a repeated measure

length.
• Muscle Strength: – 4/5 in all hip muscles, 5/5 knee & ankle
• Special Testing: – (+) FADIR Test

– (+) FABER Test • Sensitivity:44-100% , specificity: 57%-100%
* Limitations: Exam repeated from 2012 for direct comparison. No PRO’s, digital goniometry, or HHD used.
Clinical Decision Making
• Diagnosis:– Possible right hip FAI and labral pathology.
• Plan:– Referral to Orthopedic Surgeon for examination and possible magnetic
resonance arthrography.
• FAI: sensitivity: 91%, specificity: 80%
• Labral Tear: sensitivity: 87%, specificity: 64%
• Risk Factors: Identified 3 risk factors
– Extreme pelvic position
– Muscle weakness
– Age and gender
Risk Factors
Re-Injury or Future Occurrence
Extreme Pelvic Position
Anterior Tilted Pelvis Posterior Tilted Pelvis
Ross et al. 2014; Lewis et al. 2007, 2015)
Muscle Weakness
• Hip flexors (Casartelli et al. 2011,2012)
• Hip extensors (Lewis et al 2007, 2015)

11
Gender and Age
• Risk for Bilateral FAI
– Younger males with radiographic findings of a higher hip alpha angle (> 50-55⁰) and acetabular anteversion (Klingenstein et al. 2013)
Extra-Articular Hip Impingement
A New Diagnostic Category
Emerging Findings
• A subset of individuals who undergo arthroscopic hip surgery have poor outcomes.
• This growing subpopulation suggests an underlying pathology may be missed during the initial examination of a suspected intra-articular pathology.
• There is an emerging group of external hip impingement conditions that may be linked to this subpopulation.
• Four (4) specific conditions have been identified
Subspine Impingement
• Pathology: A prominent AIIS abnormally contacts the distal femoral neck during hip flexion.
– Due to an avulsion injury to the AIIS from excessive muscle activity of the rectus femorisduring repetitive knee flexion and hip extension.
• Patient: Average age: 14–30 years
• Gender: Males more than females
• Clinical Presentation:
– Complaint: "anterior hip pain”
– (+) Pain with hip flexion
– (+) Radiograph for prominent AIIS
A) Subspine Impingement
Central Iliopsoas Impingement
• Pathology: 1. A repetitive traction injury of the
iliopsoas tendon that is scarred and adherent to the capsule-labrum complex of the hip.
2. A tight or inflamed iliopsoas tendon that causes impingement during hip extension.
• Patient: Average age: 19-35 years
• Gender: Females more than males
• Clinical Presentation: – Complaint: “anterior hip pain”
– (+) Pain with hip flexion
– (+) Positive hip impingement test
– (+) MRA B) Iliopsoas Impingement
Ischiofemoral Impingement
• Pathology:
– A narrowed space between the ischial tuberosity and the lesser trochanter resulting in repetitive impingement of the quadratus femoris muscle.
• Patient: Average age: 14-30 years
• Gender: Females more than males
• Clinical Presentation:
– Complaint: non-specific pain in the hip, groin, and buttocks with active adduction and external rotation
– (+) Pain with hip extension, external rotation, and adduction
– (+) Radiographs and MRI
12
Greater Trochanteric-Pelvic Impingement
• Pathology: – A painful and pathological contact
between the greater trochanter and ilium when the hip is actively or passively moved into abduction and extension.
• Patient: Average age: 5-41 years
• Gender: No predilection
• Clinical Presentation:– Complaint: “lateral hip and groin pain”
• reproduced with active hip ABD and Ext.
– (+) Pain with hip ABD and Ext – (+) Trendelenburg gait – (+) Radiographs – *Linked to Legg–Calvé– Perthes Disease
Final Thoughts
• There is a growing body of knowledge regarding the post-surgical management of patient who underwent hip arthroscopy.
• The 4 to 5 phase post-surgical criterion based program seems to be the standard.
• Hot topics currently being studied include:
– The optimal post-surgical program
– Identifying and reducing risk factors for recurrence or new pathology during post-surgical rehabilitation.
– Identifying other forms of hip impingement
