Standard ACL Reconstruction vs ACL + Lateral Extra-Articular Tenodesis Study

Lateral extra-articular tenodesis: A 1cm wide x 8cm long strip of iliotibial band is fashioned, leaving the Gerdys tubercle attachment intact. The graft is tunneled under the fibular collateral ligament (FCL) and attached to the femur with a Richards' staple (Smith \& Nephew), just distal to the intermuscular septum, proximal to the femoral insertion of the FCL. Fixation is performed with the knee at 70 degrees flexion, neutral rotation. Minimal tension is applied to the graft. The free end is then looped back onto itself and sutured using the No. 1 vicryl.

Anatomic ACL reconstruction using a four-strand autologous hamstring graft. If the diameter of the graft is found to be less than 7.5mm, semitendinosus will be tripled (5 strand graft) providing a greater graft diameter. Femoral tunnels will be drilled using an anteromedial portal technique, with femoral fixation provided by an Endobutton or equivalent. Tibial fixation will be provided by interference screw.
