The Clinical Outcomes and Their Associated Factors in Staged Bilateral Arthroscopic Rotator Cuff Repair

摘要

PurposeTo compare perioperative characteristics and postoperative outcomes of both shoulders in patients who underwent arthroscopic bilateral rotator cuff repair sequentially and to assess the associated factors that would affect the anatomic healing in staged bilateral rotator cuff repair. MethodsThe study enrolled 64 patients who underwent bilateral rotator cuff repair with follow-up imaging at least 12?months postoperatively. We allocated the shoulders operated on first to the surgery I group and those operated on second to the surgery II group. Visual analog scale (VAS) pain and satisfaction scores, range of motion, the American Shoulder and Elbow Surgeons score, the Simple Shoulder Test score, and healing failure were evaluated. ResultsRange of motion improved with no significant between-group differences (allP> .05). In the surgery II group, VAS pain and VAS satisfaction scores were significantly worse at 6?months postoperatively (P?=?.048 andP?= .041, respectively) but were comparable at final follow-up (P?= .598 andP?= .065, respectively). American Shoulder and Elbow Surgeons and Simple Shoulder Test scores at 6?months were worse in the surgery II group (P?= .038 andP?= .048, respectively) but similar at final follow-up (P?= .786 andP?= .087, respectively). Tear size was similar between the 2 surgical procedures (κ?= 0.537,P< .001). Of the 11 patients with nonhealing in the surgery I group, 7 (63.6%) had subsequent failure in the other shoulder, and if one shoulder had healing failure, the other shoulder had a?high possibility of healing failure as well (κ?= 0.373,P?= .004). ConclusionsBilateral arthroscopic rotator cuff repair showed good outcomes at final follow-up on both sides. Tear size was closely related in both shoulders, and healing?failure?after the first rotator cuff repair was an associated factor with healing failure after the second operation.
