Femoral Fixation With Curve Cross-Pin System in Arthroscopic Posterior Cruciate Ligament Reconstruction.

ABSTRACT: Posterior cruciate ligament (PCL) ruptures account for 1% to 44% of all acute ligament injuries of the knee. In this paper we wanted to try out a system for femural fixation. Hamstring tendons are harvested and standard tibial tunnel is prepared using the transtibial PCL guide; by identifying the PCL footprint, the femoral half tunnel 27 to 30 mm with in-out technique is performed. The femoral rod of a curve cross-pin system is inserted into the anterolateral access within the femoral half tunnel. The guide block is placed 2.5 cm anterior (in a coronal plane) and 2.5 cm proximal to the lateral epicondyle. The arc attachment is assembled and the bone stock assessed with the bone gauge pin in contact with the cortex of the medial femoral condyle. Then the first sleeve over trocar is assembled, and the graft is passed through the tunnel and fixed on the femur with the pins and on the tibia with interferential screw. After biomechanical studies we obtained a maximum load at 930.95 N and maximum stiffness at 58.92 N/mm.
