Could donor tissue replace metal knee implants?

This trial is testing a new type of knee replacement for younger patients with severe knee osteoarthritis. Instead of the standard metal and plastic implant, surgeons will use a graft made of donor bone, cartilage, and meniscus to replace the damaged parts of the knee. The goal is to see if this biological approach can provide better range of motion, allowing patients to sit on the floor and maintain an active lifestyle. The study will measure how well the graft fuses with the patient's own bone and assess pain, stiffness, and physical function using the WOMAC score.
