Method for creating a double bundle ligament orientation in a single bone tunnel during knee ligament reconstruction

摘要

A method and construct for joint repair in which attachment of a double bundle graft ligament approximates anatomic orientation using interference fixation in a single bone tunnel. The double bundle graft features separable strands. A threaded screw is inserted between the separable strands and provides interference fixation of the graft against radially opposing walls defining the bone tunnel. Attachment of the graft using separated strands more closely approximate the configuration of the native ligament. The resulting reconstruction exhibits mechanical functionality that more accurately mimics that of the intact joint, with a minimum of associated tissue morbidity.

1. A method of surgical reconstruction of the anterior cruciate ligament of a knee, comprising:
forming a socket in a bone extending from a joint of the knee into the bone and having an orifice at the joint; folding over a graft having separable strands; installing a fixation device between the separable strands of the folded over graft near the orifice of the socket, the fixation device being concentrically positioned in the socket between the separable strands and axially aligned with the socket, the fixation device being oriented so as to approximate the anatomical attachment and functionality of the anterior cruciate ligament being replaced by separating and anatomically placing the separable strands of the graft with the fixation device into two anatomical bundles so as to reconstruct anteromedial and posterolateral bundles of the anterior cruciate ligament; and securing the graft in the socket with the fixation device.
