Recurrent Instability Rates (after arthroscopic stabilisation)

Recurrent Instability Rates in Contact Sports

• Non-operative = 80% [Arciero, 1994]

• Open Bankart repair = 12%• Arthroscopic Stabilisation = 14% [Larrain,

2006]

– First dislocation = 4%– Recurrent dislocations = 24%– Under 18yrs age = 30% [Nixon & Funk, 2013]

• RCT of Latarjet vs. Arthroscopic Bankart• Recurrence rate at 5 years:

– Latarjet = 12%– Arth. Bankart = 24%

• Return to sport the same!• Complication Rates higher (20%)

Latarjet Procedure [Bessier et al. JOST. 2013]

Recurrence Summary• Higher in contact/collision sport• Higher in young• Higher after surgery for recurrent

dislocations

• Arthroscopic = Open Bankart• Lower after Latarjet procedure

Injury Patterns

Clinical Examination: Instability in Athletes

• True Instability– Dislocation– Subluxation– Apprehension– Large lesions

• Subclinical Instability– Dead Arm in ABER– Pain in ABER– Clunking– No Apprehension– Smaller lesions

Investigations• No previous Surgery = MR Arthrogram

• Previous Surgery = CT Arthrogram

• An experienced Shoulder Surgeon better

• Can correlate with clinical context• Experience of reviewing Scopes & Scans

Pathology

Major ‘Minor’

• Bony Bankart• ALPSA• Rotator Cuff Tear• HAGL

• Undisplaced Labral Tear• Partial Cuff Tear

Timing of Surgery (Participation)

• Early Surgery:

– Large structural lesions

– Late in Season

– Unable to Return

• Rehab & Return:

– Minor lesions

– Early season

Types of Surgery• Mostly Arthroscopic Direct Repairs• Latarjet for High-Risk/Revision

• Anterior Instability– Revision surgery (even without bone loss)– Chronic Bony Bankart (> 3months)– Any Bony Glenoid Loss– True dislocation in Front Row forward

(Rugby Union)

– Higher level of sports
