Three cases of posterior cruciate ligament (PCL) laxity without posterolateral rotatory instability had magnetic resonance imaging scans that documented the structural continuity of the PCL. Tibial PCL recession was effective in eliminating symptomatic laxity in 1 case and lacked efficacy in the other 2 cases.
三例无后外侧旋转不稳定的后交叉韧带（PCL）松弛患者进行了磁共振成像扫描，结果显示PCL结构连续。胫骨PCL后移术在1例患者中有效消除了症状性松弛，在另外2例患者中则无效。
