Abstract
PURPOSE: To investigate the effect of suprascapular nerve release in arthroscopic rotator cuff repair surgery. METHODS: This systematic review was performed to include randomized controlled trials (RCTs) and non-RCTs that compared the outcomes of patients who did and did not receive suprascapular nerve release (SSNR) during arthroscopic rotator cuff repair surgery. MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched for relevant studies. Methodological Index for Non-randomized Studies (MINORS) was used for cohort study assessment. The Cochrane risk of bias assessment tool (version 1.0) was used to assess the risk of bias in randomized trials. The primary outcomes were pain and shoulder function. The secondary outcome was the re-tear rate. RESULTS: Two RCTs and three non-RCTs with a total of 187 patients (90 patients received SSNR and 97 patients did not receive SSNR) were included in this systematic review. The meta-analysis revealed that the SSNR group did not had a more pain reduction, assessed by visual analogue scale, compared to the non-SSNR group. Also, the SSNR group did not have a significantly more improvement in the UCLA score, compared to the non-SSNR group. In addition, there was no significant difference between the two groups in terms of Constant score and re-tear rate. CONCLUSIONS: The result of this study showed that additional suprascapular nerve release did not provide additional benefit in arthroscopic rotator cuff repair surgery. Routine arthroscopic SSNR is not recommended when treating patients with rotator cuff tear. LEVEL OF EVIDENCE: Level III.
