Method for creating a double bundle ligament orientation in a single bone tunnel during knee ligament reconstruction
First Claim
1. A method of surgical ligament repair comprising:
- forming a tibial tunnel and a femoral tunnel, each tunnel having tunnel walls;
widening the tibial and femoral tunnels by removing bone material from the tunnel walls to form tibial and femoral tunnels that are wider in one radial direction than another; and
securing a double bundle ligament graft in the widened tibial and femoral tunnels.

Abstract
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.

5. A method of graft fixation comprising:
-
removing bone to forming an axially-elongated opening;
inserting a ligament graft into the opening, the ligament graft having at least two separable strands; and
installing a fixation device between the strands of the graft. - View Dependent Claims (6, 7, 8, 9, 10, 11)
