Can your own belly fat fix your aching knee?
NCT ID NCT07405840
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether stem cells taken from a person's own belly fat can help regenerate knee cartilage and reduce pain from osteoarthritis. Sixty adults with moderate to severe knee arthritis will receive either a stem cell injection or a standard hyaluronic acid shot. Researchers will track pain, stiffness, and function over 12 months to see which treatment works better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- stromal vascular fraction (SVF) from the patient's own fat tissue
- What this could lead to
- If it works, this could offer a new way to reduce pain and improve knee function in people with osteoarthritis, potentially delaying or avoiding joint replacement.
- What could go wrong
- This is a small, single-center trial with 60 people, so results may not apply to everyone. The treatment is still experimental, and long-term benefits or risks are not yet known.
