A radially expandable sheath is provided having a substantially closed distal end with at least two sidewalls extending proximally therefrom and defining a central lumen. Each sidewall can have a substantially concave outer surface adapted to seat a graft member, and each side wall is at least partially separated by a longitudinally oriented slot that extends from a proximal end along a substantial length of each sidewall. The slot preferably terminates at a position just proximal to the distal end. The device can also include a sheath expander that is adapted to be disposed in the central lumen of the radially expandable sheath and that is configured to flex the sidewalls to radially expand the sheath so as to fix a graft member within a bone tunnel.

Flexible tibial sheath

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.

Method of performing anterior cruciate ligament reconstruction using biodegradable interference screw

A bone anchor is provided that can toggle in two planes for secure anchorage within a bone cavity. The bone anchor includes an oblique suture channel configured such that a suture strand extending through the bone anchor can be tensioned to toggle the bone anchor inside the bone cavity. The suture strand can be located on the same side of the anchor body to maximize the area of the anchor surface which engages bone, resulting in increased engagement into bone and resistance to tensile forces.
