NCT ID NCT06685120

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether a combination of platelet-rich plasma (PRP) and hyaluronic acid injections works better than either treatment alone for knee osteoarthritis. About 288 adults aged 40 to 75 with knee pain will receive one of three treatments. The goal is to see if the combo reduces pain, stiffness, and improves daily function.

What this could lead to
If it works, this could offer a more effective non-surgical option to reduce pain and improve knee function in people with osteoarthritis.
