Several factors, including compressive load and knee kinematics, have been shown to influence wear.
External knee moments (a surrogate for load) have recently been correlated with the medial and lateral wear scar areas of an unconstrained, PCL retaining knee design.
Therefore, the purpose of this study was to determine whether differences in kinetics during level walking are accompanied by specific differences in relative knee kinematics.
Thirty TKR patients were gait tested using the point cluster technique to obtain 3D motions of the knee.
External knee moments were calculated from ground reaction forces recorded with a multicomponent force plate.
The subjects were separated into two distinct anteroposterior (AP) motion categories: a low motion group and a high motion group.
Similarly, the low and high motion groups for internal-external (IE) rotation were also identified.
For the IE motion, there was no significant difference between the transverse internal rotation moments between the two IE motion groups.
However for the AP motion groups, a higher external peak flexion moment was found for the group displaying less AP motion.
These observations suggest that subjects with higher joint moments execute smaller ranges of AP motion and thus are likely to incur less wear.
