Knee surgery showdown: allograft vs autograft – which is better?

This study is for adults who have had surgery to repair multiple torn knee ligaments at once. It compares two types of tissue grafts used in the surgery: one from a donor (allograft) and one from the patient's own body (autograft). The goal is to see how well the knee works and how stable it is after recovery, using special X-rays to measure looseness. The study does not offer a new treatment but aims to gather information to help doctors choose the best graft.
