Contact study of the human hip joint was performed in order to understand load-deformation pattern under compressive loading, contact area and contact pressure by our method. Weight-bearing function of the hip joint was confirmed. Deformation of articular cartilage and subchondral bone were made reasonably and joint congruity was considered to be obtained with increasing load. Neither contact area nor distribution of the contact pressure were symmetrical or concentric, and both were dependent on the magnitude of load. The relationship between weight-bearing and early cartilage degeneration was discussed.
为了通过我们的方法了解人体髋关节在压缩载荷下的载荷-变形模式、接触面积和接触压力，进行了接触研究。证实了髋关节的负重功能。关节软骨和软骨下骨的变形是合理的，并且随着载荷增加，关节匹配性被认为得以实现。接触面积和接触压力分布均不对称或非同心，且两者均取决于载荷大小。讨论了负重与早期软骨退变之间的关系。
