Anterior deltoid reeducation for irreparable rotator cuff tears revisited.

Abstract

A previous study introduced a method of conservative treatment of irreparable rotator cuff tears (RCTs) using a rehabilitation program (anterior deltoid reeducation [ADR]). The purposes of this study were to present our experience with ADR and to compare our results with those of the previous study. Thirty consecutive elderly patients with irreparable RCTs were prospectively enrolled and taught how to perform the home-based ADR program for a period of 3 months. Clinical and radiographic evaluations were determined at the first visit. Clinical follow-up was available after 9 and 24 months. Failure of the ADR program was defined as abandonment of the ADR program because of pain and/or a patient's decision to undergo surgery at any time or a less than 20-point improvement in the American Shoulder and Elbow Surgeons score at last follow-up. Of the 30 patients, 9 did not complete the 3-month ADR program because of pain. Of the 21 patients who completed the ADR program, 3 were not satisfied with the outcome and went on to undergo surgery. Eighteen of the 30 patients completed the program and had a follow-up at 24 months. Among these 18 cases, there were significant mean improvements between pre-ADR and follow-up outcome scores among all variables (P < .005). However, 6 of these 18 patients did not have an improvement in the American Shoulder and Elbow Surgeons score by at least 20 points. Overall, the ADR program had a success rate of only 40%. A 3-month ADR program had limited success to treat irreparable RCTs. We could not reproduce the high rate of satisfactory results of 82% found in a previous study.
