In Situ Observation of Lubricant Film within Artificial Hip Joints
Original language description
The aim of this study is to clarify the interfacial lubrication processes within artificial hip joints. For this purpose, pendulum hip joint simulator in combination with thin film colorimetric interferometry was employed. The experimental device allowsto study friction and lubrication of artificial hip joints with respect to real geometry of rubbing surfaces including diameteral clearance. The contact of metal femoral head and glass acetabular cup was observed using an optical test rig, while the chromatic interferograms of contact region were captured via high-speed CMOS camera. The contact was lubricated by 25% bovine serum solution. All the measurements were conducted under body temperature of 37 °C. To investigate the influence of kinematic conditions, two different types of motions were applied. Firstly, the pendulum deflected at an initial offset angle was allowed to oscillate freely in the flexion-extension plane, while the motion was damped naturally. Under these transient co
