华南人胫骨平台后倾角的三维测量及临床意义

Abstract

Abstract:

Objective　To provide references and evidences for design of the knee prosthesis suitable for south Chinese and optimal tibial osteotomy in total knee arthroplasty, posterior slope angle of the tibial plateau in adult south Chinese were measured.　Methods　80 adult volunteers were enrolled in this experiment. Their knees were scanned by spiral CT with obtained data imported into MIMICS for three-dimensional reconstruction; then both of posterior slope angle of the lateral tibial plateau and the medial tibial plateau were measured by Unigraphics NX software.　Results　The posterior slope angle of the medial tibial plateau in adult south Chinese was (6.86±1.92)° for the left, and (6.45±2.02)° for the right, (6.20±2.03)° for the male and (7.19±1.78)° for the female, with an average of (8.16±3.37)°; and posterior slope angle of the lateral tibial plateau was (6.89±3.42)° for the left, (6.82±2.78)° for the right, （6.84±2.82）° for the male and （6.87±3.01）° for the female, with an average of （6.85±2.90）°. There were no statistically significant differences between different genders and sides for posterior slope angle of the lateral tibial plateau or the medial tibial plateau（P>0.05）; However, the posterior slope angle of the medial tibial plateau was significantly greater than the lateral tibial plateau(P<0.05).　Conclusions　The posterior slope angle in adult south Chinese has a greater individual difference than the average in other area at home and abroad.
