Arthroscopy 2022 May;38(5):1454-1456

Since the introduction of superior capsular reconstruction (SCR) for the treatment of irreparable rotator cuff tears nearly 10 years ago, we have witnessed widespread adoption by the arthroscopic shoulder community alongside an exponential increase in use within North America. To date, more than 42,000 acellular dermal allografts have been implanted in the United States alone, and our indications and surgical technique have been progressively refined in response to the evolving body of clinical outcomes research. However, with P values set aside, the real question still remains: how do our patients actually do after SCR? With the advent of clinically significant outcomes such as the patient acceptability symptomatic state and substantial clinical benefit, investigators have sought to establish more practical, patient-centered benchmarks for success after an intervention.

Vail, Colorado.

Massive irreparable rotator cuff tears in young, active patients pose a challenging treatment dilemma. Since the relatively recent development of the superior capsular reconstruction (SCR) procedure, the technique has been increasingly used to stave off reverse total shoulder arthroplasty in this demographic. As a result of continued output of supportive literature, both biomechanically and clinically, SCR has been adopted by surgeons despite some technical aspects of the procedure not being fully elucidated.

Institute of New Drug Development, China Medical University, Taichung.

A rotator cuff tear is an age-related common cause of pain and disability. Studies including our previously published ones have demonstrated that mesenchymal stem cells cultured under hypoxic conditions [hypoxic multipotent stromal cells (MSCs)] facilitate the retention of transplanted cells and promote wound healing. However, there are very few, if any, reports targeting the punctured supraspinatus tendons to create more or equally serous wounds as age-related tears of rotator cuff. Read More
