Preparation of the Femoral Tunnel through Anteromedial Portal during Arthroscopic Single Incision Anterior Cruciate Ligament Reconstruction


The original technique for endoscopic anterior cruciate ligament reconstruction has several potential complications because of constraints imposed by working through the tibial tunnel: improper femoral tunnel placement, violation of the femoral tunnel posterior wall, femoral interferenc screw divergence, graft laceration during screw insertion, and distal tibial bone block prr>trusion. We performed 25 endoscopic anterior cruciate ligament reconstructions with bone-tendon-bone graft using a mo3ified technique that minimizes each of these problems, through the use of a anteromedial portal more centrally and distally placed than the original that portal. Postoperative radiographic review showed femoral screw divergence in 20% of cases (2 in the anteroposterior plane, 2 in the lateral plane and 1 in both planes), but the average angles (AP: 0.52+- 1.85, Lateral: 1.48+-3.30) were insignificant. There was no graft damage during screw insertion or grafttunnel mismatch. We concluded that this modified technique allows simplified, reproducible tunnel and interference screw placement.
