Biomechanical Responses and Injury Characteristics of Knee Joints under Longitudinal Impacts of Different Velocities

Figure 2

The development of the finite element model of the knee joint. (a) Initial inverse knee joint model showing a high-order surface after the smoothing processing. (b) The construction of cancellous bone and cortical bone boundaries; the inward bias of the cortical bone was set at 1.5 mm. (c) The articular cartilage thickness of the knee joint was set at 1 mm, and the cartilage thickness at the tibiofibular joint was set at 0.375 mm. (d) The reconstructed meniscus and cruciate ligament. (e) The mesh structure of the knee joint. (f) The completed finite element model of the knee joint.
