Trial Parameters
Brief 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.
