“…Our findings were consistent with tibial translational movements detected in previous studies (Fig. 6), [12][13][14][15] with the tibia moving posteriorly and superiorly during full flexion. When the lateral and medial cartilage compartment translations were compared with translation of the tibia, the observed and 90 flexion, posterior translations of the lateral cartilage contact points were similar to previously published results 16 The medial and lateral translations of the tibia and cartilage contact points changed in a similar manner based on the degree of flexion.…”

“…We therefore compared our results on VV and IE rotations of the tibia in an intact knee with published data and plotted changes in lateral and medial cartilage contact positions with respect to tibial rotations. 6,14,[17][18][19] As shown in Fig. 7, between 0 and 90 flexion, the trajectory of ML translation of the lateral cartilage contact position is similar to the trajectory of VV rotations in Refs.…”

The purpose of this study was to create a kinematic model of the knee joint with six degrees of freedom (DOF) and evaluate the effect of medial collateral ligament (MCL) and lateral collateral ligament (LCL) rupture on cartilage contact point distribution on the tibia during flexion. We hypothesized that collateral ligament contributions vary over six DOF of knee joint articulation and affect the cartilage contact point distribution during joint articulation. The ligament contributions and distribution of joint cartilage contact points cannot be fully assessed with simplified joint models or invasive experiments. Therefore, we developed a new model in which the tibia and femur centers of mass were determined from their surface geometry, and the displacement of the moving tibia was determined from the displacements of the attached ligaments. Compared to the intact knee, the tibia with the LCL removed had higher medial translation and lower valgus rotation. The tibia with the MCL removed had higher lateral translation and higher valgus rotation than the intact knee. At 0 , 30 , and 60 , the tibia with the LCL removed had more internal rotation than the intact knee. Understanding six DOF knee joint kinematics with integration of ligament contributions and cartilage contact positions is useful for the diagnosis of ligament injuries and the design of articulating surfaces for total arthroplasty.

The knee joint is one of the most complicated joints in the human body. Fundamental knowledge about kinematics is essentially important in order to design knee prostheses which are functionally similar to the knee joint. In addition, the prosthesis should carry out similar kinematics, since only the geometrical resemblance is insufficient. As an initial step, an experimental apparatus, a test protocol and an evaluation method were developed which allows the investigation of the human knee joint kinematics. Based on the results of multiple experiments, a reference function was determined, which provides guidance on how the flexionrotation function in the human knee joint can be described. The function also provides reference about the kinematics which should be defined in the design of prostheses, and to what extent does an arbitrary knee prosthesis follows the required kinematics. The definition of knee rotation is reported in this article.
