The effect of postoperative sling immobilization and early mobilization on clinical and functional outcomes after arthroscopic rotator cuff repair: A propensity score-matched analysis

Abstract

BACKROUND: Optimal postoperative management is controversial after arthroscopic rotator cuff repair (ARCR).OBJECTIVE: The aim of the study was to evaluate outcomes of patients with and without postoperative sling immobilization after undergoing arthroscopic RCR rotator cuff repair.METHOD: 369 arthroscopic full thickness superior rotator cuff tears (RCT) with a minimum follow-up of 6 months were included in this study. Propensity score matching was performed for age, sex, BMI, and tear size. Pain (VAS score), shoulder range of motion (ROM), functional outcome (ASES, Constant-Murley [CM] and Oxford shoulder score [OSS]), and health related quality of life (SF-36) scores were compared between patients with and without sling immobilization.RESULTS: According to the propensity match score, 92 patients (50 sling immobilization and 42 no sling immobilization) were matched to be almost identical in age (62.5 +/- 8.0 vs. 61.8 +/- 5.9), sex (female 78% vs. 76.2%), BMI (28.1 +/- 2.8 vs. 27.8 +/- 2.6), and tear size (2.7 +/- 1.1 vs. 2.9 +/- 0.8). The postoperative physical functioning domain of SF-36 scores was found to be significantly higher in the no sling group (p = 0.034).CONCLUSION: Early mobilization after arthroscopic small and medium sized full thickness superior rotator cuff repair is associated with improved ROM and quality of life scores.
