本研究通过结合动态活动中胫骨股骨接触的透视分析和同一患者的植入物回收分析，描述了体内膝关节运动学与聚乙烯损伤之间的关系。6例患者（8膝）行保留后交叉韧带全膝关节置换术。所有患者在关节置换术后平均18个月的上下楼梯活动和跑步机步态期间均参与了透视分析，并测量了关节接触。随后，所有聚乙烯胫骨植入物在平均26个月的体内功能后被取出：尸检时3个，翻修时5个。在活动期间，在取出的插入物上的损伤位置和在透视下测量的关节接触位置之间存在统计学上显著的相关性。股骨接触和聚乙烯损伤主要发生在胫骨关节面后半部分，损伤模式在腔室中最大，每位患者体内股骨接触范围最大。本研究表明，体内透视分析可以预测聚乙烯关节表面的损伤位置。
This study characterizes the relationship between in vivo knee kinematics and polyethylene damage by combining fluoroscopic analysis of tibiofemoral contact during dynamic activities and implant retrieval analysis in the same patients. Six patients (eight knees) underwent posterior cruciate ligament-retaining total knee arthroplasty. All patients participated in fluoroscopic analysis during a stair-rise and descent activity and treadmill gait an average of 18 months after arthroplasty, and articular contact was measured. Subsequently, all polyethylene tibial inserts were retrieved after an average of 26 months in vivo function: three at autopsy and five at revision. There was a statistically significant correlation between the damage location on the retrieved inserts and the articular contact location measured fluoroscopically during the activities. The femoral contact and polyethylene damage occurred predominantly on the posterior half of the tibial articular surface, and the damage pattern was largest in the compartment with the greatest range of in vivo femoral contact for each patient. This study showed that in vivo fluoroscopic analysis can predict the damage location on the polyethylene articular surface.
