Video Summary

Dr. Johnstone shares 10 key lessons from 28 years researching posterior shoulder instability, highlighting differences between overhand and contact athletes. Overhand athletes often face indirect injury mechanisms and have poorer surgical outcomes, with 70% returning to sport using suture anchors, while contact athletes show 93% return and satisfaction. Posterior instability commonly coexists with labral tears, rotator cuff issues, and bone changes like glenoid dysplasia and retroversion. Physical exams like load and shift tests guide treatment, but some conditions require surgery. Arthroscopic repair is preferred, avoiding electrothermal methods due to high failure. Overhand athletes benefit from looser repairs; contact athletes do better with tighter repairs.
