Sports after shoulder arthroplasty: a comparative analysis of hemiarthroplasty and reverse total shoulder replacement

BackgroundTraditionally, fewer postoperative sport restrictions are imposed on hemiarthroplasty (HHA) patients on than reverse total shoulder arthroplasty (RTSA) patients. However, functional outcomes have been shown to be superior in RTSA. No direct comparison of RTSA vs HHA has been done on rates of return to sports in patients with glenohumeral arthritis and rotator cuff dysfunction, proximal humeral fractures, or rheumatoid arthritis.MethodsThis is a retrospective review of consecutive RTSA and HHA patients collected from our institution's shoulder arthroplasty registry. All patients playing sports preoperatively with minimum 1-year follow-up were included. Final follow-up included an additional patient-reported questionnaire with questions regarding physical fitness and sport activities.ResultsThe study included 102 RTSA and 71 HHA patients. Average age at surgery was 72.3 years for RTSA compared with 65.6 years for HHA (P < .001). Patients undergoing RTSA had improved visual analog scale scores compared with HHA (−5.6 vs −4.2, P = .007), returned to sports after RTSA at a significantly higher rate (85.9% vs 66.7%, P = .02), and were more likely to be satisfied with their ability to play sports (P = .013). HHA patients were also more likely to have postoperative complaints than RTSA patients (63% vs 29%, P < .0001). No sports-related complications occurred. Female sex, age <70 years, surgery on the dominant extremity, and a preoperative diagnosis of arthritis with rotator cuff dysfunction predicted a higher likelihood of return to sports for patients undergoing RTSA compared with HHA.ConclusionsDespite traditional sport restrictions placed on RTSA, patients undergoing RTSA can return to sports at rates higher than those undergoing HHA, with fewer postoperative complaints.
