Knee fluid drain or blood injection may curb arthritis after ACL tear

NCT ID NCT07142369

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests two procedures done before ACL surgery: draining excess knee joint fluid (arthrocentesis) or injecting platelet-rich plasma (PRP) from the patient's own blood. The goal is to see if either reduces inflammatory chemicals linked to cartilage damage. About 99 adults aged 18-50 with a recent ACL tear and swelling will take part. The results could help prevent long-term arthritis after knee injuries.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Platelet-rich plasma (PRP)
What this could lead to
If it works, this could point toward a way to reduce joint inflammation and cartilage breakdown after an ACL tear, potentially lowering the risk of post-traumatic arthritis.
What could go wrong
This is a small, early-stage study (99 people) testing a procedure, not a drug. The benefits may be modest or not show up at all, and PRP injections carry a small risk of infection or pain at the injection site.
