摘要

目前全膝关节置换术(TKR)装置的成功取决于体内生理活动中的运动学和接触力学。大量的研究都是为了确定对关节长期正常功能有重要意义的参数。超高分子量聚乙烯(UHMWPE)全关节置换部件的潜在磨损性能指标包括关节接触应力和面积,胫骨-股骨和髌骨-股骨运动学。所有这些都被用来比较植入物的设计,并作为区分系统的基础。

A Total Knee Replacement Model for Evaluation of Joint Mechanics
The success of current total knee replacement (TKR) devices is contingent on the kinematics and contact mechanics during in vivo physiological activity. A great deal of research has gone into determining parameters important to proper long-term joint function. Indicators of potential wear performance in ultra-high molecular weight polyethylene (UHMWPE) total joint replacement components include contact stress and area due to articulations, and tibio-femoral and patello-femoral kinematics. All have been used to compare implant designs and serve as a basis for differentiation of systems.
