History and Future Direction of Superior Capsule Reconstruction for Irreparable Rotator Cuff Tears
Journal Title: Journal of Clinical Orthopaedics - Year 2018, Vol 0, Issue 0
Abstract
Lesions of the superior shoulder capsule had been a neglected entity before I reported my technique for superior capsule reconstruction (SCR).I had noticed that patients with irreparable rotator cuff tears always had irreparable defects of the superior shoulder capsule as well as the rotator cuff tendons, because the superior shoulder capsule is attached to the undersurface of these tendons. Therefore, I hypothesized that reconstruction of the superior shoulder capsule might be useful to prevent superior migration of the humeral head and subacromial impingement in irreparable rotator cuff tears. To prove my hypothesis, our group performed a cadaveric biomechanical study in 2005. This biomechanical study showed that SCR completely restored superior stability of the glenohumeral joint, whereas patch grafting to the supraspinatus tendon (conventional patch graft surgery) only partially restored superior translation to the intact level. Consequently, in 2007,we started arthroscopic SCR for patients with irreparable rotator cuff tears. From our 10 years of experience with SCR, we conclude that arthroscopic SCR restores superior glenohumeral stability and improves shoulder function in irreparable rotator cuff tears.
