Patent ID: 8435293

Claim:
A method for fixing a ligament graft in a bone tunnel comprising the steps of: forming a bone tunnel through bone; providing a ligament graft fixation system having an expandable sheath having proximal and distal ends with at least two sidewalls extending therebetween and defining a central lumen, each sidewall being spaced apart from one another by a longitudinally oriented open slot at a proximal-most end of the expandable sheath and extending along a substantial length of each sidewall; inserting the expandable sheath into the bone tunnel while tensioning an end of a graft member outside of the tunnel, such that the graft member is positioned between one of the sidewalls of the expandable sheath and the bone tunnel; inserting an expansion plug into the expandable sheath to expand a region of each sidewall of the expandable sheath thereby compressing the graft member between at least one of the sidewalls and the bone tunnel to thereby fix the graft member within the bone tunnel.
