ABSTRACT
PURPOSE: To compare postoperative pain and clinical outcome after arthroscopic rotator cuff repair in patients immobilized with an abduction brace versus patients placed in an antirotation brace. METHODS: One hundred twenty patients (72 women and 48 men) with symptomatic degenerative complete tear of the supraspinatus or infraspinatus tendons were included in the study. Exclusion criteria were history of trauma/traumatic tears, concomitant shoulder pathology, psychological illnesses, and previous shoulder surgery. The Constant-Murley score (CMS) was obtained before surgery and at 3 months, 6 months, and 1 year after surgery. The visual analogue scale (VAS) was done on the day of surgery and at 1 week, 3 weeks, 6 weeks, and 3 months after surgery. Postoperative isokinetic muscle strength evaluation was done for the shoulder external rotator at 1 year. RESULTS: Mean age was 50.4 years for the abduction brace group (ABG) and 50.8 years for the open pouch arm sling group (PASG). The mean level of the VAS score ranged from 75.6 for the ABG and 74.9 for the PASG on the day of the operation to 17.7 and 18.5 at 3 months after surgery. In both groups, the repeated measure analysis of variance showed that there were highly significant changes (P < .001) in the VAS from the day of operation to 3 months after surgery. A significant improvement was detected in both groups in the mean level of the CMS, from 40.9 for the ABG and 41.2 for the PASG before surgery to 84.7 and 84.5 at 1 year after the operation. There was no statistically significant difference between the 2 groups regarding the isokinetic muscle strength, VAS, or the CMS. CONCLUSIONS: Our study did not find a significant difference between abduction brace and antirotation sling in patient-oriented outcome measures or postoperative pain after rotator cuff repair. LEVEL OF EVIDENCE: Level II, prospective comparative study.
