A novel technique for subscapularis repair in total shoulder arthroplasty

Abstract

Anatomic total shoulder arthroplasty, when used for treatment of primary glenohumeral arthritis, is historically very successful. We propose a novel technique for subscapularis repair during closure of a deltopectoral approach to the shoulder with subscapularis peel. Our technique allows for early motion following surgery and also provides for improved subscapularis repair integrity and resilience during postoperative rehabilitation. Postoperatively, we allow passive and active assisted range of motion at week 1, limited active range of motion at week 2, and unrestricted external rotation range of motion beginning at week 6. The use of our technique has led to improved patient outcomes with regard to range of motion postoperatively following anatomic total shoulder arthroplasty and we recommend its adoption into practice.
