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.
