PURPOSE: To compare the outcomes of total shoulder arthroplasty (TSA) with posterior capsule plication (PCP) and reverse shoulder arthroplasty (RSA) in patients with primary osteoarthritis, posterior subluxation, and bone loss (Walch B2). PATIENTS AND METHODS: All shoulders undergoing anatomic TSA with PCP were retrospectively identified (group 1, G1) and compared to shoulders undergoing RSA (group 2, G2) for Walch B2 osteoarthritis. There were 15 patients in G1 (mean (SD) age and follow-up of 70.5 (7.5) years and 42.8 (18.4) months, respectively) and 16 patients in G2 (mean (SD) age and follow-up of 72.6 (5.4) years and 35.1 (14.2) months, respectively). RESULTS: Both groups had substantial improvements in pain and function. In G1, results were excellent in 80% and satisfactory in 20%, compared to 81% and 6% in G2, respectively ( p = 0.2). The mean (SD) American Shoulder and Elbow Surgeons score was 91.2 (6.7) and 80.3 (14.3) in G1 and G2, respectively ( p = 0.08). The mean Simple Shoulder Test score was 10.6 in G1 and 8.5 in G2 ( p = 0.01). There were no reoperations in either group, but G1 had seven postoperative complications. CONCLUSIONS: The outcomes of TSA with PCP are comparable to RSA in patients with osteoarthritis and biconcave glenoids. However, TSA leads to more complications while RSA leads to lower functional outcomes.
