Abstract: The invention relates to an anchoring device for urging a ligament transplant against the wall of a bone hole during ligament replacement and for fixing the anchor in position in the said bone hole. The device has a first component and a second component designed for mutual sliding co-operation between a first anchor inserting position and a second fixation position. The sliding co-operation is provided along respective parallel inner mating surfaces of each component which surfaces are each in angular relation to the respective component outer surfaces and in opposed angular relation to each other so that in the anchor insertion position the width of the said anchoring device is in an elongate narrow mode with respect to a bone hole and, in the fixation position, the width of the said anchoring device is in a compressed wide mode to thereby urge the ligament against the wall of the bone hole. A method of ligament fixation in a bone hole is also disclosed.

Abstract: The invention relates to a ligament fixation device for the fixation of an anterior cruciate ligament in the knee joint which device can be inserted into appropriately drilled holes in the femur and/or tibia to locate the replacement therein. The device comprises an outwardly expandable compression member and a pair of anchoring members. The compression member has a first surface and a second surface, spaced from the first surface and joined to the first surface by a side wall. The side wall of the compression member extends from a narrower first surface to a wider second surface. The wall of the compression member includes a plurality of spaced slits.
