The purpose of this study was to answer 2 questions: Does the posterior cruciate ligament (PCL) produce femoral rollback in a single-design, cruciate-sparing total knee arthroplasty (TKA)? Does the PCL prevent posterior tibial displacement when it is retained after a single-design, cruciate-sparing TKA? Knee kinematics and limits of motion were measured with the knees in the following states: (1) intact knee, (2) anterior cruciate-deficient knee, (3) PCL-retaining total knee of a single design (TKA), (4) PCL-retaining TKA with PCL cut, and (5) PCL-substituting TKA. Femoral rollback was then calculated from the above data. The results showed that the PCL was able to prevent posterior translation and maintain femoral rollback when it was preserved during TKA. Therefore, the PCL can be functional after TKA, in a single-design, cruciate-sparing TKA. When the PCL was cut, significant changes in knee kinematics were observed.
在单设计、保留交叉韧带的全膝关节置换术（TKA）中，后交叉韧带（PCL）是否会产生股骨后滚？在单设计、保留交叉韧带的TKA术后保留PCL时，它是否能防止胫骨后移？在膝关节处于以下状态时测量膝关节运动学和活动范围：（1）完整膝关节，（2）前交叉韧带损伤膝关节，（3）单设计的保留PCL的全膝关节（TKA），（4）保留PCL但PCL已切断的TKA，以及（5）替代PCL的TKA。然后根据上述数据计算股骨后滚。结果表明，在TKA术中保留PCL时，它能够防止胫骨后移并维持股骨后滚。因此，在单设计、保留交叉韧带的TKA中，PCL在TKA术后仍可发挥功能。当PCL被切断时，观察到膝关节运动学有显著变化。
