Posterior cruciate ligament injury is one of the most common problems in sports medicine. The treatment of choice for this injury is posterior cruciate ligament reconstruction, which improves the biomechanical and clinical stabilities of the knee. There are many graft choices, of which the bone-patellar tendon-bone (BPTB) graft is a popular option. In applying the BPTB graft, most surgeons use the transtibial technique by passing the graft from the tibial tunnel to the femoral tunnel, which is normally performed without problems, but there is a chance of patellar tendon fiber damage because of the sharp turn required from the tibial tunnel to the femoral tunnel. To minimize this risk, herein we propose a transportal graft passage technique with which it is easy to pass the BPTB graft and reduce the risk of graft damage.
后交叉韧带损伤是运动医学中最常见的问题之一。这种损伤的首选治疗方法是后交叉韧带重建，它可改善膝关节的生物力学和临床稳定性。有多种移植物可供选择，其中髌腱骨（BPTB）移植物是一种常用的选择。在应用BPTB移植物时，大多数外科医生采用经胫骨技术，即将移植物从胫骨隧道穿过至股骨隧道，通常这种操作没有问题，但由于从胫骨隧道到股骨隧道需要急转弯，存在髌腱纤维损伤的风险。为了将这种风险降至最低，在此我们提出一种经皮移植物通过技术，利用该技术可以轻松通过BPTB移植物并降低移植物损伤的风险。
