1·Methods: The twist Angle and eversion Angle were measured on 81 sets (male 41 and female 40) of tibiae.
方法：对国人胫骨81副(男41副，女40副)进行下段扭转角及外翻角测量。
2·Twelve weeks after surgery, pure screw titanium implants were placed in the proximal metaphyses of the tibiae of rats in both groups. The rats were killed at 4 and 12 weeks after implant surgery.
术后12周于大鼠胫骨处植入纯钛螺纹状种植体，并于种植术后4周及12周分两批处死大鼠；
3·Result Right tibiae had markedly less deformities than left ones at 4, 8, and 12 weeks after transfer of cultured cartilages.
