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 $\pm$ 8.0 vs. 61.8 $\pm$ 5.9), sex (female 78% vs. 76.2%), BMI (28.1 $\pm$ 2.8 vs. 27.8 $\pm$ 2.6), and tear size (2.7 $\pm$ 1.1 vs. 2.9 $\pm$ 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.
