Patent ID: 6953463

Claim:
An interference screw for cortical and cancellous bone fixation of a soft tissue graft within a bone tunnel, comprising: a threaded body extending between a proximal end and a distal end along a central axis and being sized and configured for threadable insertion into a bone tunnel, the threaded body further comprising: a proximal threaded section for cortical bone fixation comprising a proximal thread and having an average diameter; and a distal threaded section for cancellous bone fixation, disposed between the proximal threaded section and the distal end, comprising a distal tread and having a constant diameter that is less than the average diameter of the proximal threaded section, the distal threaded section having a length that is greater than the length of the proximal threaded section in order for the interference screw to apply force along a greater distance in the cancellous bone region compared to the cortical bone region, the proximal end having an angle relative to the central axis in a range of about 10° to about 80°, the proximal and distal threads having the same pitch.
