Management of rotator cuff injuries using allogenic platelet-rich plasma.

Rotator cuff injuries are a major cause of shoulder pain, affecting the quality of life and producing a significant burden on healthcare systems. Conservative management modalities are prioritized, resorting to surgery only when required. The field of regenerative medicine involving the use of biologics, such as platelet-rich plasma (PRP), has evolved and shown potential for managing rotator cuff injuries. Nonetheless, limitations including subpar outcomes have led clinicians to question the efficacy of autologous PRP. To circumvent this, the possibility of utilizing a standardized and well-characterized allogenic PRP for RCI has been explored. In this manuscript, we qualitatively present the evidence from in vitro, pre-clinical, clinical and ongoing studies investigating the applications of allogenic PRP in the context of rotator cuff disorders. Administration of allogenic PRP is safe and potentially efficacious to manage rotator cuff injuries, though more adequately powered randomized controlled trials with longer follow-ups are warranted to further establish the efficacy of allogenic PRP and justify its routine clinical use.
