Title: Knee Joint Loads and Kinematics: New Insights into Cartilage Tribology
Abstract: Tribology is the study of interacting surfaces in motion, which encompasses friction, lubrication, and wear. Biotribology is the specific sub-field that studies biological systems through tribological methods. Conducting biological research with tribological principles generally includes a system approach that allows for the ability to study multiple interconnected components, which includes the articulating bodies, the interfacial medium and surrounding environment.
A major characteristic of healthy articular cartilage is its load-bearing function; however, the current understanding of the mechanical effects of compression and shear during articulation on cartilage health remains elusive. The assessment of early changes in cartilage mechanical properties associated with loss of function has been challenging. To obtain more information, we started to study cell response, and mechanical and structural changes at the surface after the application of tribological stresses.
