后交叉韧带保留型全膝关节置换术后，后交叉韧带在深屈时常绷紧，难以达到适当的张力。在这项研究中，后交叉韧带部分松解后的运动和最大屈曲进行了评估。部分松解改善了最大屈曲角度，并保持了前后稳定性，而不会引起运动学的不良变化，而完全切除后交叉韧带会引起不利的前后不稳定。部分后交叉韧带松解消除了后交叉韧带过紧引起的过度后滚运动，也使关节面接触点向前移动。这些结果表明，后交叉韧带部分松解可以改善全膝关节置换术后后交叉韧带过紧患者的膝关节功能。
Appropriate tension of the posterior cruciate ligament, which often is tight in deep flexion, is difficult to achieve after posterior cruciate ligament retaining total knee arthroplasty. Kinematics and maximum flexion after partial release of the posterior cruciate ligament were evaluated in this study. A partial release improved the maximum flexion angle and maintained anteroposterior stability without causing undesirable changes in kinematics, whereas full resection of the posterior cruciate ligament caused unfavorable anteroposterior instability. Partial posterior cruciate ligament release eliminated excessive rollback movement caused by a tight posterior cruciate ligament and also shifted the point of articular surface contact anteriorly. These results indicate that partial release of the posterior cruciate ligament may improve knee function in patients with a tight posterior cruciate ligament after total knee arthroplasty.
