Design outcomes

Primary

Measure	Time frame
The clinical outcome at 6 months, 12 months, 24 months, 5 years, and 10 years measured using the Western Ontario Shoulder Instability Index of patients treated with a J-bone graft or Latarjet procedure for post-traumatic recurrent anterior shoulder instability with significant glenoid defect	—

Secondary

Measure	Time frame
1. The resorption/remodeling of both graft types is compared using pre-operative, post-operative, 12-months and 24 months post-operative CT imaging 2. The clinical outcome at 6 months, 12 months, 24 months, 5 years, and 10 years measured using the Subjective Shoulder Value of patients treated with a J-bone graft or Latarjet procedure for recurrent anterior shoulder instability 3. The clinical outcome at 6 months, 12 months, 24 months, 5 years, and 10 years measured using the Rowe Score and range of motion of patients treated with a J-bone graft or Latarjet procedure for recurrent anterior shoulder instability 4. Radiological assessment of osteoarthritic changes in the operated joint compared to the contra-lateral joint by bi-plane radiography of both shoulders at 5 years and 10 years follow up compared to the base-line images of both shoulders	—
