Twenty-three patients had 25 total knee arthroplasties. The flexion and extension gaps were measured before and after resection of the posterior cruciate ligament. The extension gap increased 2.0 +/- 0.2 mm in the medial compartment and 1.9 +/- 0.3 mm in the lateral compartment. The flexion gap increased 1.4 +/- 0.2 mm in the medial compartment and 2.3 +/- 0.3 mm in the lateral compartment. All increases were statistically significant.
23例患者共进行了25次全膝关节置换术。在切除后交叉韧带前后测量屈伸间隙。内侧间室的伸直间隙增加了2.0±0.2毫米，外侧间室增加了1.9±0.3毫米。内侧间室的屈曲间隙增加了1.4±0.2毫米，外侧间室增加了2.3±0.3毫米。所有增加均具有统计学意义。
