Open vs. arthroscopic acromioplasty: a prospective, randomized study.
Between May 1988 and May 1990, 44 patients with Stage II impingement were randomized into open and arthroscopic treatment groups. Forty-one patients were available for final follow-up in May 1991: 22 in the open group, 19 in the arthroscopic group. Comparisons of pain, function, motion, and strength were made preoperatively and at 2, 6, 12, 26, and 52 weeks postoperatively. Final analysis showed that the main benefits of arthroscopic acromioplasty were evident in the first 3 months postoperatively. Arthroscopic patients regained flexion and strength more rapidly than did open patients, had shorter hospitalizations, used less narcotics, and returned more quickly to both work and activities of daily living. By 3 months postoperatively, open patients tended to "catch up" with arthroscopic patients, and further recovery was equivalent. In both groups, full recovery took at least 1 year for the majority of patients and in both groups at 1 year > 90% of patients achieved a satisfactory result. Because of its medical and economic advantages for both the patient and the health-care system, we conclude that arthroscopic acromioplasty should become the procedure of choice for patients with impingement syndrome refractory to conservative treatment.
