The results of posterior cruciate ligament (PCL) reconstruction with the patellar bone-tendon-bone graft performed in 21 patients between 1984 and 1989 were compared with the results of PCL reconstruction using the iliotibial band performed in 12 patients between 1980 and 1984. Much better results were obtained from the procedure using the patellar tendon. Four factors are considered to be responsible for the improvement: precise preoperative assessment of the pathomechanics of the posterior instability and simultaneous correction of collateral laxities if present; isometric placement of the PCL graft; use of a biomechanically sound graft and its secure fixation in the knee; and the concept of full extension of the knee to protect the graft from undue posterior stress during the early postoperative period.
对1984年至1989年间21例采用髌腱骨-肌腱-骨移植进行后交叉韧带（PCL）重建的结果，与1980年至1984年间12例采用髂胫束进行PCL重建的结果进行了比较。采用髌腱的手术获得了更好的结果。有四个因素被认为是导致改善的原因：术前对后向不稳定的病理力学进行精确评估，如有侧副韧带松弛则同时进行矫正；PCL移植物的等长放置；使用生物力学性能良好的移植物并将其牢固固定于膝关节；以及在术后早期使膝关节完全伸直以保护移植物免受过度后向应力的理念。
