Not Applicable
Not yet recruiting
Conditions
Posttraumatic Osteoarthritis
Anterior Cruciate Ligament (ACL) Rupture
Registration Number
NCT07142369
Lead Sponsor
Rush University Medical Center
Brief Summary

The purpose of this study is to determine what effects the withdrawal of excess knee joint fluid or the injection of a factor from the blood has on swelling after a sudden anterior cruciate ligament (ACL) rupture of the knee.

Detailed Description

The body responds to different stresses by releasing factors in the blood and fluids in response to stressors like injury, surgery or certain treatments. Some of these factors help heal and some make the injury and body swell (inflammation). In this study we want to see if the intervention of withdrawing fluid the knee or the addition of an enriched healing factor called platelet rich plasma (PRP) injected in the knee influences the body to produce healing factors in the knee joint fluid.
