Clinical Study After Reconstruction of the Posterior Cruciate Ligament: Factors on Posterior Stability


The goals of treatment in the injuries of posterior cruciate ligament(PCL) are restoration of normal tibiofemoral stability and reduction of long term osteoarthrosis of the knee. The purpose of this study is to analyze the factors on posterior stability and functional result after PCL reconstruction. From March 1996 to April 1997, twenty operation on PCL reconstruction were carried out in our hospital. The functional results according to the criteria of the Lysholm knee score and stress radiograph for posterior stability were evaluated. The average functional results evaluated by Lysholm knee score was 87. There was no significant difference in functional result according to selected grafted material, combined knee injury, type of injury and arthrotomy, etc. Difference in posterior tibial translation on average were 2.8mm in acute and 7.7mm in chronic injury. In posterolateral combined injury, average posterior tibial translation in pos- terolateral repair was 3.2mm and in posterolateral reconstruction was 9.4mm. In PCL reconstruction using hamstring with repair of PCL remnant was 2mm. In conclusion, to obtain the good result on posterior sta- bility, early PCL reconstruction using hamstring with repair of PCL remnant, and appropriate treatment on combined posterolateral injury were recommended.
