Reverse Total Shoulder Arthroplasty Outcomes with and without Subscapularis Repair: A Retrospective, Comparative Study


Subscapularis repair after a lateralized Reverse shoulder arthroplasty (RSA) remains controversial. It is not known whether this non-anatomic repair can help with Range of motion and/or stability following RSA. The objective of this retrospective study is to determine if there is any difference in stability, range of motion, stability, revision, infection, or surgical time after RSA with or without subscapularis repair. 230 RTSA patients were included in this retrospective review. We collected data on range of motion, surgical time, range of motion, and complications including joint instability. This was analyzed using a multivariable model controlling for age, BMI, sex, and the presence of comorbidities. Instability was determined as a documented dislocation requiring closed or open reduction. Both instability and range of motion measurements were completed by an ABOS Board Certified Orthopaedic Surgeon pre-operatively and at 3, 6, and 12 week follow-up appointments.
