Clinical and functional outcomes for patients following rotator cuff repair surgery, with or without adjuvant platelet rich plasma injections

Tendon-bone healing following rotator cuff repair correlates with a successful outcome. With the relatively high re-tear rates reported in the literature despite multiple surgical and suture anchor techniques, there has been an increase in research into biological adjuvant therapies that elevate local growth factor concentrations ,to assist structural tendon healing following rotator cuff surgery .The purpose of this research was to determine if post-operative and repeated application of platelet-rich plasma to the tendon repair site improves early tendon healing and enhances functional recovery following double row arthroscopic supraspin tus repair. A secondary objective was to determine if partial re-tears early post-surgery reveal differences in subjective function or objective isokinetic strength, compared to completely intact tendon repairs; and if early tendon healing can be predicted using these measures, independent of medical imaging.
