Postoperative PRP Injection may Not Enhance ACL Reconstruction Outcomes: Study
Researchers in a recent study have found that postoperative intra-articular platelet-rich plasma (PRP) injection does not lead to superior improvement in knee symptoms and function compared to no injection after anterior cruciate ligament reconstruction (ACLR). This study was published in JAMA Network Open by Zipeng Ye and colleagues.
Anterior cruciate ligament (ACL) injuries are common in athletes and individuals engaging in physical activities, often requiring surgical intervention for reconstruction. Platelet-rich plasma (PRP) therapy has emerged as a potential adjunctive treatment for musculoskeletal injuries due to its purported ability to enhance tissue healing and regeneration. However, its efficacy in ACL reconstruction outcomes remains uncertain, with conflicting evidence from previous studies.
To compare subjective outcomes and graft maturity in patients undergoing ACL reconstruction with and without postoperative PRP injection. This randomized clinical trial included 120 patients aged 16 to 45 undergoing ACL reconstruction at a national medical center in China. Patients were randomized to receive either postoperative PRP injection (n=60) or no injection (n=60). Follow-up occurred for 12 months. Patients in the PRP group received 3 doses of intra-articular PRP injection at monthly intervals postoperatively, while the control group did not receive PRP injection. Both groups underwent the same rehabilitation protocol and follow-up schedule.
