This clinical study investigates the outcomes of bone-patellar tendon-bone and quasi-anatomical meniscus allograft transplantation techniques in patients requiring joint reconstruction. The study aims to assess the safety, efficacy, and functional improvements following these transplant procedures, utilizing donor tissues to restore joint function and alleviate pain in individuals with severe knee damage. Participants will undergo the transplantation procedure and be monitored for post-operative recovery, complications, and long-term outcomes, including joint stability and mobility. The study seeks to provide valuable insights into the effectiveness of these advanced surgical techniques for knee joint repair.
