Method of performing anterior cruciate ligament reconstruction using biodegradable interference screw

摘要

A method of replacing an ACL with a graft. The method provides for the drilling bone tunnels in a femur and a tibia. A replacement graft is provided having first and second ends. A biodegradable composite screw is provided. The screw is made from a biodegradable polymer and a bioceramic or a bioglass. At least one end of the graft is secured in a bone tunnel using the biodegradable composite screw.

1. A method of replacing an anterior cruciate ligament in a knee, comprising:
inserting a biodegradable composite interference screw into a bone tunnel between an interior surface of the bone tunnel and a first end of a graft mounted within the bone tunnel, said interference screw comprising a biodegradable comprising a copolymer of poly (lactic acid) and poly(glycolic acid), and a bioceramic; and rotating the interference screw such that the screw is substantially contained within the bone tunnel, and the first end of the graft is fixed in place between the interference screw and a section of the interior surface of the bone tunnel; wherein the biodegradable, composite interference screw degrades in the body.
