Del Core MA, Cutler HS, Ahn J, et al. - In this study, clinical, radiographic, and functional outcomes were compared between subscapularis tenotomy (ST), lesser tuberosity osteotomy (LTO), and subscapularis peel (P) techniques. Researchers conducted a level III systematic review and network meta-analysis matching subscapularis tenotomy, lesser tuberosity osteotomy, and subscapularis peel in patients undergoing anatomic total shoulder arthroplasty. For the meta-analysis, eight studies met the inclusion criteria. In comparison with ST and P groups, LTO has superior healing and postoperative subscapularis specific physical exam tests. Nevertheless, there was no variation in the postoperative range of motion between the groups and all techniques demonstrated good functional patient-reported outcomes, with a low rate of postoperative complications. These data serve evidence-based support that subscapularis tenotomy, peel, and lesser tuberosity osteotomy all indicate similar outcomes thus, selection should be based on surgeon experience and comfort.
