Similar outcomes between transtendon repair and tear completion repair techniques for partial articular‐sided supraspinatus tendon avulsion lesions: a systematic review and meta‐analysis

Abstract

AbstractPurposeThis study aimed to review studies comparing transtendon repair (TTR) with tear completion repair (TCR) techniques for partial articular‐sided supraspinatus tendon avulsion (PASTA) lesions according to postoperative patient‐reported outcomes and complications.MethodsDatabases, including PubMed, Embase, Scopus, and Cochrane, were searched for studies published between 2008 and 2022 that directly compared the postoperative patient‐reported outcomes and complications of the TTR and TCR techniques for PASTA lesions. Odds ratios (ORs) were calculated for dichotomous outcomes, while mean differences (MDs) were calculated for continuous outcomes.ResultsA total of seven studies (497 shoulders) were analysed. No statistically significant differences in the postoperative clinical outcomes at the final follow‐up were observed between the TTR and TCR techniques for PASTA lesions. The overall retear rates of the TTR and TCR techniques were 7.7% and 11.6%, respectively (corresponding healing rates were 92.3% and 88.4%), whereas the overall occurrence rates of adhesive capsulitis were 4.7% and 3.3%, respectively. Furthermore, no significant difference was observed in postoperative range of motion (forward flexion, MD = − 1.22, 95% confidence interval (95%CI) − 5.28 to 3.34, n.s.; external rotation, MD = − 1.39, 95% CI − 3.19 to 0.42, n.s.), overall retear rate (OR 0.72, 95% CI 0.29–1.08, n.s.), and occurrence rate of adhesive capsulitis (OR 1.11, 95% CI 0.35–3.52, n.s.) between the two techniques.ConclusionBoth techniques improve clinical outcomes while having a low complication rate and a high rate of healing. No significant difference in clinical outcomes was observed between the two techniques.Level of evidenceIII.
