3D-Printed knee repair: custom grafts aim to heal damaged cartilage

This study is testing a new surgical method to repair damaged knee cartilage. It uses 3D printing to create a precise, custom-fit bone graft from the patient's own tissue, combined with their own concentrated healing factors (platelet-rich plasma). Researchers will compare this combined approach to a standard graft in 60 adults with moderate-to-severe knee cartilage injuries to see if it improves knee function, reduces pain, and leads to better cartilage repair.
