Project overview
This 10-year retrospective study evaluated outcomes of 200 shoulder arthroplasty patients treated at a tertiary center, comparing anatomic total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA). Patients had indications including osteoarthritis (47%), rotator cuff arthropathy (35%), and complex fractures (18%), with a mean age of 68 years and 60% being female. Functional outcomes improved significantly: Constant-Murley scores rose from 35 to 74, and ASES scores from 35 to 76 (p < 0.001). Anatomic TSA demonstrated slightly better postoperative function, particularly in external rotation, whereas RTSA was more effective in patients with compromised rotator cuffs. The overall complication rate was 8%, with prosthetic loosening (3%) and periprosthetic fractures (2%) being most common, primarily in older or comorbid patients. Radiographic assessments confirmed good implant positioning with occasional scapular notching in RTSA cases. These findings affirm both TSA and RTSA as effective procedures.
