Dual-photon absorptiometric bone-mineral assay, penetration tests, and axial compression tests of the proximal tibial epiphyses were carried out in 18 human cadaver knees. The reproducibility of bone mineral assay was within +/- 12% (95% tolerance limits). Linear regression analysis with bone-mineral content as the independent variable showed a good correlation to the ultimate force obtained from the compression tests on the medial (r = 0.81) and the lateral (r = 0.90) condyles. The correlation between bone mineral content and an average of three condylar penetration tests was somewhat weaker (medical condyle: r = 0.65, lateral condyle: r = 0.62). It is concluded that dual-photon absorptiometric bone-mineral assay may be a suitable noninvasive alternative to bone-strength measurement and thus suitable for monitoring the changes in tibial condylar bone during follow-up studies.
对18个尸体人膝关节进行了双能X线吸收法骨矿物质测定、穿透试验以及胫骨近端骨骺的轴向压缩试验。骨矿物质测定的重现性在±12%以内（95%的容许限）。以骨矿物质含量作为自变量的线性回归分析显示，与在内侧髁（r = 0.81）和外侧髁（r = 0.90）进行压缩试验所获得的极限力具有良好的相关性。骨矿物质含量与三个髁穿透试验平均值之间的相关性稍弱（内侧髁：r = 0.65，外侧髁：r = 0.62）。得出的结论是，双能X线吸收法骨矿物质测定可能是一种合适的非侵入性骨强度测量替代方法，因此适用于在随访研究中监测胫骨髁骨的变化。
