Rabbit Knee Joint Biomechanics: Motion Analysis and Modeling of Forces during Hopping

摘要: Although the rabbit hindlimb has been commonly used as an experimental animal model for studies of osteoarthritis, bone growth and fracture healing, in vivo biomechanics knee joint have not quantified. The purpose this study was to investigate kinematic kinetic patterns during hopping adult rabbit, develop a estimate contact force distribution between tibial plateaus. Force platform data three-dimensional motion analysis using infrared markers mounted on intracortical pins were combined calculate ankle intersegmental forces moments. A statically determinate developed predict muscle, ligament tibiofemoral stance phase hopping. Variations kinematics permitted identification two landing patterns, that could be distinguished by variations magnitude external abduction moment. During hopping, prevalence moment led prediction higher passing through lateral compartment compared medial joint. These results represent critical joint, which allow comparisons both other models human knee, may provide further insight into relationships mechanical loading, growth, healing.
