准确捕捉骨骼和软骨的形态并生成网格仍然是膝关节计算建模工作流程中的关键步骤。目前，没有标准化的方法来比较不同单元类型和节点密度的网格，这使得跨研究团队的比较成为一个巨大的挑战。本文的目的是描述一种独立于骨和软骨网格拓扑结构的量化膝关节骨和软骨网格差异的方法。使用涉及配准、重采样和径向基函数拟合的一系列步骤获得任意类型网格的骨网格到网格的距离、软骨下骨边界和软骨厚度，之后执行比较。软骨下骨边界和软骨厚度被计算并在一个共同的参照系中可视化，以供比较。将所建立的方法应用于五个建模团队开发的模型。我们获得骨骼网格到网格距离的方法减少了选择参考网格时出现的发散(即比较网格A到B与网格B到A)。总的来说，不同团队的骨骼形态是相似的。计算了所有模型的软骨厚度，并给出了平均绝对软骨厚度差，关节面积在不同组之间具有最好的一致性。两个团队在软骨下骨边界问题上存在分歧。本文提出的方法允许对与网格类型和节点密度无关的骨和软骨几何形状进行客观比较。
Accurately capturing the bone and cartilage morphology and generating a mesh remains a critical step in the workflow of computational knee joint modeling. Currently, there is no standardized method to compare meshes of different element types and nodal densities, making comparisons across research teams a significant challenge. The aim of this paper is to describe a method to quantify differences in knee joint bone and cartilages meshes, independent of bone and cartilage mesh topology. Bone mesh-to-mesh distances, subchondral bone boundaries, and cartilage thicknesses from meshes of any type of mesh are obtained using a series of steps involving registration, resampling, and radial basis function fitting after which the comparisons are performed. Subchondral bone boundaries and cartilage thicknesses are calculated and visualized in a common frame of reference for comparison. The established method is applied to models developed by five modeling teams. Our approach to obtain bone mesh-to-mesh distances decreased the divergence seen in selecting a reference mesh (i.e., comparing mesh A-to-B versus mesh B-to-A). In general, the bone morphology was similar across teams. The cartilage thicknesses for all models were calculated and the mean absolute cartilage thickness difference was presented, the articulating areas had the best agreement across teams. The teams showed disagreement on the subchondral bone boundaries. The method presented in this paper allows for objective comparisons of bone and cartilage geometry that is agnostic to mesh type and nodal density.
