Jenssen KK, et al. - In a prospective randomized controlled non-inferiority trial, researchers sought to compare the clinical and radiologic results among patients with 3 vs 6 weeks of immobilization after arthroscopic rotator cuff (RC) repair. Improved postoperative shoulder function was resulted by RC repair, regardless of whether the shoulder was immobilized for 3 or 6 weeks. With regard to the Western Ontario Rotator Cuff (WORC) index at 12 months' follow-up, findings suggested non-inferiority of three weeks of postoperative immobilization with sling use to the commonly used regimen involving 6 weeks of immobilization in a brace. Between the groups, similar degrees of healing was indicated by MRI. Results demonstrated the safety of immobilizing patients in a simple sling for 3 to 6 weeks after repair of small to medium RC tears.
