Cruciate ligament reconstruction with tibial drill guide

摘要

A method of ligament reconstruction in which at least one ligament replacement is extended between two bone plugs and fixed within each of two bone tunnels in the bones of a joint using interference screws. The bone plugs are given two substantially parallel grooves longitudinally in which the ligament replacements are seated. The ligament replacement may be a semitendinosus tendon attached to itself to form a loop attached to each of the two bone plugs. The bone plugs may be autogenous by using a coring reamer when forming the bone tunnels. A bone block drill guide having three parallel columns can be used to form the substantially parallel grooves in the bone plugs. A trefoil rasp has three cutting lobes, two opposite each other and one approximately equidistant from the other two. The rasp forms three channels in the bone tunnels, two for the looped tendon and one for the interference screw. A tibial drill guide directs a coring reamer without use of a guide wire.
