Platelet Rich Plasma (PRP) Treatment of the Anterior Cruciate Ligament Injured Knee to Decrease the Risk of Post-traumatic Osteoarthritis (PTOA): a Randomized Double-blind Controlled Trial
Hospital for Special Surgery, New York
Summary
The purpose of our study is to examine the effect of platelet-rich-plasma (PRP) injection on the short-term resolution of post-injury inflammation (biomarkers) and improvement in joint function in patients with acute ACL injury. This RCT has been powered based on the questionnaire KOOS Jr. but it is considered a 'pilot study' in terms of the lab analysis proposed.
Description
Anterior cruciate ligament (ACL) injury is one of the most common clinical problems among active individuals, with over 250,000 ACL reconstructions (ACLR) per year in the United States. Surgical reconstruction of the ACL is typically required in individuals who wish to return to an active lifestyle due to the presence of knee instability. The results of ACLR are predictably good as far as the ability to re-establish knee stability and to allow return to cutting and pivoting activities. However, there is a lack of effective interventions that can successfully delay or prevent the progressive de…

Interventions
- Procedureplatelet rich plasma (PRP) injection
We aim to evaluate early catabolic and inflammatory changes in knee joints in patients receiving PRP injections following ACL injury, as these patients are at higher risk of developing PTOA. We also aim to establish correlations between markers of biologic activity of PRP and clinical outcomes (including both patient-reported outcomes and clinical functional outcomes), with emphasis on cellular and molecular inflammatory parameters modulated by PRP.
- Procedureplacebo saline injection
Patients randomized into the control arm will receive the placebo or saline injection
