Comparing Anatomic and Reverse Shoulder Replacement Surgery for Arthritis of the Shoulder in Adults Aged 65 to 85

What this Trial Is About

Researchers are evaluating the functional outcomes of two types of shoulder replacement surgeriesanatomic total shoulder arthroplasty TSA and reverse total shoulder arthroplasty RTSAfor patients with primary glenohumeral osteoarthritis who have intact rotator cuffs and no significant glenoid retroversion. The study aims to determine if RTSA provides at least as good results as anatomic TSA and also to explore whether RTSA might lead to better clinical and radiographic outcomes with fewer complications. Participants will be randomly assigned to receive either an anatomic TSA or an RTSA through a deltopectoral surgical approach. Both procedures involve implanting a prosthesis designed to treat primary glenohumeral arthritis. The study compares these two surgical options over a follow-up period of two years. During the study, patients will be assessed using several measures including the American Shoulder and Elbow Surgeons ASES score, Subjective Shoulder Value SSV, range of motion, pain on a visual analog scale, Constant score, and Short Form-12 SF-12. Radiographic evaluations and complication rates will also be recorded over the two-year postoperative period. The total participation duration includes baseline assessment and follow-up evaluations spanning up to two years after surgery.
