An interference screw for affixing soft tissue grafts during anterior cruciate
ligament (ACL) reconstruction comprises a threaded body axially extending between
a face and a tip along a central axis, with the face advantageously being obliquely
aligned with the central axis. The threaded body includes a proximal threaded section
and a distal threaded section, each of which may be straight or tapered. The proximal
threaded section is approximately 1 mm larger in diameter than the distal threaded
section. The increased diameter of the proximal threaded section enables the interference
screw to compressively secure the soft tissue graft against the cortical bone,
while the distal threaded section compresses the soft tissue graft against the
cancellous bone with an appropriately reduced force that is appropriate for facilitating
bonding of the soft tissue graft to the cancellous bone and that is sufficient
for minimizing any "bungee effect."
