Non-acute Rotator Cuff Tear: Repair Augmented with Reconstituted Absorbable Collagen Scaffold (RACS)- Systematic Review

Background: There have been studies indicating that the non acute rotator cuff repair can be augmented withreconstituted absorbable collagen scaffold (RACS) which results in better structural integrity and functional outcome.Hence, this review aims to systematically analyse the available evidence based on its methodological quality, techniqueand functional outcome.Methods: Systematic review was carried on PubMed for articles related to non acute rotator cuff repair reconstitutedabsorbable collagen scaffold . Also, Colemans method of scoring was used to assess the methodological quality of thestudies.Results: Among the studies included, the minimum follow up duration was ۱۲ months. All the studies reportedstatistically significant improved outcomes following repair with reconstituted absorbable collagen scaffold for partialthickness tears, full thickness tears and in massive tears.Conclusion: Repair reconstituted absorbable collagen scaffold seems to be a viable option to improve the structuralintegrity following non acute rotator cuff repair.Level of evidence: I
