Direct Answer
Yes, Stanford researchers developed a treatment targeting the enzyme 15-PGDH that regrows knee cartilage in animal models and human tissue. Human clinical trials have not yet been completed, so it is not yet an approved treatment.
What the Evidence Shows
Stanford researchers did publish peer-reviewed findings in Science demonstrating that inhibiting the enzyme 15-PGDH with a small-molecule compound promotes cartilage regeneration in aged and injured mice, and early tests on human cartilage tissue from osteoarthritis patients showed promising signs of reduced degradation and early regeneration. The mechanism works by reprogramming existing cartilage cells, shifting them away from a degenerative state rather than relying on stem cells. The claim is accurate in its core assertion, with one caveat: this is not yet an approved treatment. Human clinical trials have not been completed, so calling it a ready-to-use therapy overstates where the science currently stands.
