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.

Active substance

a mixture of donor stem cells and the patient's own cartilage cells, applied with a glue-like gel during surgery

What this could lead to

If successful, this could offer a simpler, one-time surgical treatment for knee cartilage damage, potentially delaying or preventing osteoarthritis.

What could go wrong

This is a small Phase 3 trial with only 60 people. The treatment requires surgery, and long-term benefits or risks are not yet fully known. Results may not apply to everyone.
