Abstract

|
|
Purpose:Conventional transtibial approach for the anterior cruciate ligament (ACL) reconstruction tended to place the femoral tunnel in too vertical position (11 or 1 o’clock), which could provide the postoperative anteroposterior (AP) stability but not provided the rotational stability. Therefore we present a surgical technique to make the transtibial femoral tunnel at 10 or 2 o’clock position.
Surgical approach:To make a transtibial femoral tunnel at the 10 or 2 o’clock position, the direction and position of the tibial drill guide was important. We set the tibial drill guide at 40~45 degrees and the intraarticular guide tip was 1 mm anterior and medial to the conventional site. The starting point for the guide pin on the proximal tibia was proximal to the pes anserinus and anterior to the medial collateral ligament. The tibial tunnel was initially drilled 1 mm less than the diameter of the graft. Then femoral offset guide could be easily placed at 10 or 2 o’clock position through the tibial tunnel. The tibial tunnel and the femoral tunnel of 30 mm in length were made with the reamer that was same size with the graft.
Conclusions:We report a surgical technique to create a transtibial femoral tunnel at 10 or 2 o’clock position in ACL reconstructionto provide the rotational stability as well as the AP stability.
