The results highlight a deeper connection between the cartilage friction and the lubrication film formation, which allows for better understanding of the cartilage lubrication mechanism.īiotribology cartilage fluorescence microscopy friction lubrication reciprocating tribometer. A decreasing trend of protein cluster count, which corresponds to a decrease in the thickness of the lubrication film, is found in all experiments. The results show a more significant impact of albumin proteins on the lubrication process, whereas its clusters create a more stable lubrication layer. The primary results explaining a connection between lubrication and friction are presented. The experiments with cartilage samples and model synovial fluid are carried out, and the new software is applied to provide their evaluation. The evaluation software and the follow-up evaluation procedure are also described. The software allowing for snaps processing and subsequent evaluation of fluorescence records is developed. INTRODUCTION Knee joint is the largest and most complex joint in human body. General Terms Medical image processing, Computer vision, Pattern recognition Keywords Cartilage thickness, MRI, Osteoarthritis, Knee joint, Image segmentation. A newly developed device, a reciprocating tribometer, is used to allow for simultaneous measurement of friction forces with contact visualization by fluorescence microscopy. visualization, thickness measurement, volume measurement and validation methods. This can contribute to better understanding of lubricating film formation in a natural synovial joint. The present paper deals with a new method for visualization of lubricating film with simultaneous measurements of the friction coefficient. The right functioning of natural synovial joints ensures well lubricated contact surfaces with a very low friction coefficient and wear of cartilage tissue. A healthy natural synovial joint is very important for painless active movement of the natural musculoskeletal system. ![]()
