During arthroscopic posterior cruciate ligament (PCL) reconstruction, passage of the graft into the knee joint may be difficult, especially when using the patellar tendon. Because of the angle of passage, the bone block ends may become entangled or caught on the superior edge of the posterior tibial tunnel when passing the graft from the tibia to the femur. The use of a blunt trocar through the posteromedial portal avoids impingement of the bone block against the edge of the tibial tunnel. This method uses the pulley principle and permits the graft to pass freely into the knee. This method has been used successfully by the authors in more than 40 PCL arthroscopic reconstructions.
在关节镜下后交叉韧带(PCL)重建术中,将移植物植入膝关节可能会很困难,尤其是使用髌腱时。由于植入角度的原因,当将移植物从胫骨穿过至股骨时,骨块末端可能会在胫骨后隧道的上边缘处缠绕或受阻。通过后内侧入路使用钝性套管针可避免骨块撞击胫骨隧道边缘。该方法利用了滑轮原理,使移植物能够自由进入膝关节。作者已在40余例关节镜下PCL重建术中成功应用了此方法。
