The Effects Of Superior Capsular Reconstruction On In Vivo Kinematics, Glenohumeral Motion, And Patient-Reported Outcomes

Video Transcription

Video Summary

Dr. Jillian Cain presented research on superior capsule reconstruction (SCR) for irreparable rotator cuff tears, analyzing its impact on shoulder kinematics and clinical outcomes. The study tracked 10 patients pre- and one-year post-SCR, measuring acromiohumeral distance and humeral head position during shoulder motion. Results showed no significant increase in static or dynamic acromiohumeral distance post-surgery, with minimal changes in humeral head positioning. Despite limited kinematic changes, patient-reported outcomes improved significantly, suggesting that clinical benefits of SCR may not rely on altered joint mechanics. This challenges prior cadaver studies and highlights the complexity of SCR’s therapeutic effects.
