II Systematic review of literature.

The OLP could be considered for primary shoulder stabilization, particularly in competitive athletes, who have high functional demands and great risks of redislocation.

BackgroundRotator cuff tears are associated with capsular contraction and stiffness that should be restored before surgical repair. Corticosteroid injections (CSIs) are frequently used as conservative treatments before surgical repair. This study aimed to determine the influence of preoperative and postoperative CSIs on clinical and anatomic outcomes after rotator cuff repair.MethodsThe authors analyzed the records of 257 patients who had arthroscopic rotator cuff repair, of whom 212 were evaluated at 3.1 ± 1.0 years (median, 2.9 years; range, 1.4-7.1 years) by clinical (Constant score) and ultrasound (Sugaya classification) examinations. Univariable and multivariable regressions were performed to determine associations between outcomes and administration of preoperative and postoperative CSIs, patient characteristics, and tendon characteristics.ResultsThe Constant scores improved from 56.4 ± 15.1 to 80.8 ± 12.5. Multivariable regression confirmed that postoperative scores were associated with postoperative CSIs (P < .001), preoperative scores (P < .001), gender (P < .001), and fatty infiltration (P < .005). Retears (Sugaya types IV-V) were observed in 27 shoulders (13%). Multivariable regression clarified that retear rates were associated only with postoperative CSIs (P = .007) and stage 3 fatty infiltration (P = .001). Adjusting for confounders, an additional postoperative CSI would decrease scores by 4.7 points and double retear risks.DiscussionPreoperative CSIs had no influence on clinical scores and retear rates, whereas postoperative CSIs were associated with lower scores and more retears. Although we can infer that preoperative CSIs do not affect outcomes, we cannot determine whether postoperative CSIs compromised outcomes or were administered in patients who had already poor outcomes. Our findings may resolve controversies about the administration of preoperative CSIs.
