Rehabilitation protocols following rotator cuff repair: a meta‐analysis of current evidence

Rotator cuff tears are a common shoulder pathology with an increasing incidence. The optimum post-operative rehab protocol remains unclear and can consist of either conservative rehabilitation or more aggressive early range-of-motion. Multiple studies have assessed these treatment protocols. This meta-analysis aims to compare post-operative clinical outcomes following either conservative or aggressive rehabilitation post rotator cuff repair.A systematic electronic literature search was undertaken using a number of databases. Eligible studies included randomized control trials published between January 2013 and April 2019 in English with patients having had received rotator cuff repair. Post-operative clinical outcomes considered included shoulder range-of-motion, overall function status (Costant-Murley score) and rates of rotator-cuff re-tear. Studies were evaluated for methodological quality in accordance with the Physiotherapy Evidence Database (PEDro) scale. Summarized pooled statistics were calculated using Review Manager (v5.3) software.A total of six randomized controlled trials were included. Standardized mean difference (SMD) in shoulder flexion, abduction and external rotation was not statistically significant at either 6 or 12 months post rotator cuff repair. Functional assessment suggests a slight benefit in Constant-Murley Score (SMD = 1.77; 95% CI -3.93, 7.47) in aggressive treatment groups with no significant risk increase for cuff re-tear (RR = 1.22; 95% CI 0.60, 2.47).This meta-analysis suggests there is no clear benefit of either rehabilitation protocol when considering range-of-motion, with a possible benefit in functional outcome at the cost of increased re-tear risk post aggressive rehabilitation. Both protocols have been shown to offer safe reproducible short- and long-term outcomes.
