New One-Shot knee cartilage repair shows promise in trial
NCT ID NCT04236739
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 3 trial tested a new one-step treatment called IMPACT for knee cartilage damage. It combines the patient's own cartilage cells with donor stem cells, applied during a single surgery. 60 people aged 18-45 with moderate to severe cartilage lesions were randomly assigned to either IMPACT or standard care (physical therapy and pain medication). The study aimed to see if IMPACT improves knee symptoms and quality of life more than standard care alone.
