ABSTRACT
PURPOSE:
The aims of this pilot randomised controlled trial (RCT) were to assess the safety and efficacy of a human dermal allograft patch and assess the feasibility of a future RCT comparing retear rate and functional outcome 12 months following standard and augmented double-row rotator cuff repair.METHODS:
A pilot RCT was conducted among patients undergoing arthroscopic repair of rotator cuff tear measuring between 1 and 5 cm. They were randomised to either augmented (double-row repair with human acellular dermal patch) or standard (double-row repair only). The primary outcome was rotator cuff retear determined on MRI scan at 12 months using the Sugaya's classification (grade 4 or 5). All adverse events were recorded. Functional assessment was performed at baseline and 3, 6, 9, and 12 months post-surgery using clinical outcome scores. Safety was assessed by complications and adverse effects, and feasibility by recruitment, follow-up rate and proof of concept statistical analyses of a future trial.RESULTS:
Between 2017 and 2019, 63 patients were considered for inclusion. Twenty-three patients were excluded, leaving 40 patients (20 per group) in the final study population. The mean tear sizes were 3.0 cm in the augmented and 2.4 cm in the standard group. There was one adhesive capsulitis in the augmented group, with no other adverse events. Retear was observed in 4/18 (22%) of patients in the augmented and 5/18 (28%) in the standard group. In both groups, functional outcome improved significantly which was clinically meaningful for all scores, with no difference between groups. Retear rate increased with tear size. Future trials are feasible but need a minimum total sample size of 150 patients.CONCLUSION:
Clinically meaningful improved function without adverse effects was found with human acellular dermal patch-augmented cuff repairs. LEVEL OF EVIDENCE Level II.Key words
