Objectives: The study was to establish a precise three-dimensional (3D) finite element model (FEM) of the distal radioulnar joint (DRUJ) and then to validate its accuracy for the application to the research on clinical biomechanics. Materials and methods: The right forearm DRUJ of a volunteer (male, 28 years old, 62 kilograms) was scanned by computed tomography (CT) and magnetic resonance imaging (MRI). The resulting sectional images were input into MIMICS10.1 and ANSYS10.0 to generate 3D FEM of the DRUJ. With this FEM, the bending load, axial compression load and the torsion load conditions were simulated, and the vonmises stress distribution of the DRUJ was detected. The simulation results were compared with the biomechanics experiment results which were reported by the literatures. Results: The constructed FEM consisted of 333,805 elements and 508,384 nodes. Together, the simulation results with this FEM were in consistent with those of the reported experiments in bending load, axial compression load and torsion load conditions. Discussion: The 3D FEM of the DRUJ can reflect the real geometric structure of the DRUJ objectively and the simulation with this FEM can predict the results of the biomechanics experiments successfully.

The goal of this study is to quantify changes in knee joint contact behavior following varying degrees of the medial partial meniscectomy. A previously validated 3D finite element model was used to simulate 11 different meniscectomies. The accompanying changes in the contact pressure on the superior surface of the menisci and tibial plateau were quantified as was the axial strain in the menisci and articular cartilage. The percentage of medial meniscus removed was linearly correlated with maximum contact pressure, mean contact pressure, and contact area. The lateral hemi-joint was minimally affected by the simulated medial meniscectomies. The location of maximum strain and location of maximum contact pressure did not change with varying degrees of partial medial meniscectomy. When 60% of the medial meniscus was removed, contact pressures increased 65% on the remaining medial meniscus and 55% on the medial tibial plateau. These data will be helpful for assessing potential complications with the surgical treatment of meniscal tears. Additionally, these data provide insight into the role of mechanical loading in the etiology of post-meniscectomy osteoarthritis.
