结果当股骨假体的旋转与经股骨上髁轴平行时，测得的髌股关节峰值接触压结果最优（P< 0．05）。
Results The rotational alignment of the femoral components paralleled to the transepicondylar axis had the best results of the peak value of the patellofemoral contact pressure(P< 0. 05).
为重建正常关节线保证假体旋转，我们以股骨髁上轴为参考。
To reestablish the joint line and set the component rotation, we referenced the femoral epicondylar axis.
目的：使用第一代单轴锁定钢板固定髁上股骨骨折越来越普遍。
Objectives: Uniaxial, first-generation locking plates have become increasingly popular for fixation of supracondylar femur fractures.
结论：测试所用的可使用多轴固定螺钉的钢板系统，在生物力学方面是股骨髁上骨折的不错的选择。
Conclusions: The tested plate construct with its polyaxial locking screw mechanism provides a biomechanically sound fixation option for supracondylar femur fractures.
在除去韧带的情况下，髁突绕本身的轴作中心定轴转动，该中心位于髁嵴下方6毫米处，运动发生在髁突与关节盘之间。
In specimen without ligaments, the condylar process rotates around a central axis about 6 mm underneath the condylar crest. The movement occurs between the condylar process and the articular disc.
