The effect of total shoulder arthroplasty on self-assessed health status is comparable to that of total hip arthroplasty and coronary artery bypass grafting

The purpose of this study was to assess the impact of total shoulder arthroplasty on the self-assessed health status of a large series of patients with glenohumeral osteoarthritis. In 91 patients we were able to compare the 8 quantitative domains of Short Form-36 (SF-36) before surgery and at 30 to 60 months after surgery. These preoperative and postoperative scores were compared with data from an age- and gender-matched control population. These results were also compared with those reported for patients who underwent other common, effective surgical procedures. Preoperative SF-36 values were significantly lower than population controls for 6 of 8 SF-36 domains (physical function, social function, physical role function, emotional role function, vitality, and comfort). Patients improved significantly in 4 of 8 SF-36 domains at 30 to 60 months after total shoulder arthroplasty: physical role function (P < .01), comfort (P < .01), social function (P < .01), and mental health (P < .05). Although the improvements were significant and similar to the postoperative scores reported for total hip arthroplasty and coronary bypass procedures, the scores did not reach those of the general population.
