Platelet-Rich Plasma Therapy for Rotator Cuff Injuries: A Comprehensive Review of Current Evidence and Future...

Rotator cuff injuries are a prevalent cause of shoulder pain and disability, significantly impacting daily activities and quality of life. Platelet-rich plasma (PRP) therapy has emerged as a potential treatment for these injuries, aiming to enhance healing by delivering concentrated platelets and growth factors. This review comprehensively evaluates the current evidence regarding PRP therapy for rotator cuff injuries. It examines clinical trial data, comparing PRP therapy with conventional treatments such as physical therapy and surgical intervention. The review also explores the biological mechanisms of PRP, including its role in promoting tendon repair and regeneration through growth factors and cytokines. In addition, it addresses variables that may affect PRP therapy outcomes, including preparation techniques, injection methods, and patient-specific factors. The review highlights the need for standardized protocols and further research to optimize PRP therapy and address existing gaps in knowledge. Future directions include exploring combined treatment approaches and assessing long-term outcomes to refine PRP therapy's role in rotator cuff injury management. This review aims to provide valuable insights into the effectiveness of PRP therapy, contributing to improved treatment strategies and enhanced patient outcomes.
