Purpose: To compare outcomes after conversion of anatomic total shoulder arthroplasty (aTSA) to reverse total shoulder arthroplasty (RTSA) and a matched cohort. Methods: Patients converted from aTSA to RTSA for rotator cuff failure or component loosening and a primary RTSA matched cohort were retrospectively identified from a prospective database. Demographics and preoperative and postoperative outcomes were obtained and compared. Results: Age, sex, body mass index, follow-up length, and preoperative function were similar between revision (n = 35) and primary (n = 70) groups. At final follow-up, visual analog scale pain (2.4 +/- 2.8 versus 1.7 +/- 2.8; P = 0.24) and American Shoulder and Elbow Surgeons (68 +/- 26 versus 76 +/- 24; P = 0.14) scores were similar. The revision group had worse subjective shoulder value scores (63 +/- 30 versus 79 +/- 21; P = 0.002), satisfaction (74% versus 90%; P = 0.03), and more complications (31% versus 13%; P = 0.02). Conclusion: Revision of aTSA to RTSA for component loosening or rotator cuff failure results in function comparable to primary RTSA; however, more complications, worse subjective shoulder value scores, and lower patient satisfaction should be expected.
