ACL graft fixation device and method

摘要

An improved anchor for securing a graft ligament in place in a bone tunnel comprises a dome portion surrounded by a flange portion. The dome portion fits into a bone tunnel and includes first and second apertures for receiving sutures located on so that the anchor is positioned stably in use, while the flange portion abuts the outer surface of the bone and supports the anchor. The cross-sectional thickness of the anchor is increased in the area of the apertures to provide adequate pull-out strength. The flange may be elliptical in plan and the dome portion asymmetric, to allow the anchor to better withstand tension.
