Since full rotation of the thighbones can no longer occur in the hip joints, much of the rotational torque is transferred to the knees and the lumbar spine—a recipe for knee and lower back injuries.

结果是大腿骨无法充分由髋关节旋转就会造成部分的受力转移到膝盖和下腰椎上—正是膝盖和下腰痛的邀请函。

CONCLUSION: at the beginning phase of rotation, the common injuries of knee joint of the athletes are left knee medial accessory ligament and meniscus.

结论：旋转开始阶段，运动员膝关节易发生左膝内侧副韧带损伤和膝内侧半月板损伤。

Conclusion it is in accordance with biomechanics to treat medial knee degenerative arthritis and patellofemoral arthritis due to tibial rotation, which has satisfactory long term result.

结论胫骨高位截骨、胫骨结节旋转抬高治疗膝关节内侧间隔退行性关节炎、胫骨旋转所致髌股关节炎，符合生物力学要求，长期随访效果满意。
