Observation of lubrication mechanisms within artificial hip joints
Original language description
Despite the rapid improvement of hip joint replacements, limited longevity of implants still represents its substantial limitation. Therefore, it is necessary to ensure sufficient service life of replacements to avoid its failure and consequent revising operations. As the main cause leading to implant failure is aseptic loosening due to osteolysis, it is desired to clarify the tribological processes inside the joints. In the present paper, we aimed on the investigation of lubricant film formation between femoral head and transparent acetabular cup from optical glass. The effect of material, geometry and the composition of model synovial fluid was examined, while the experiments were realized using pendulum hip joint simulator (Fig. 1). The contact was lubricated by various model synovial fluids. The applied approach is based on the combination of the two optical methods; optical interferometry and fluorescent microscopy. Utilizing of the fluorescent method enabled to employ also poly(methyl methacryla
