The tests were performed using vibrotribometer «Optimol SRV». Sinovial fluid obtained from the patient with posttraumatic knee synovitis and distilled water was used as lubrication. Dependence of the cartilage thickness decrease due to abrasion and deformity on pressure value in friction block was detected. It was shown that total disappearance of cartilage with 1.8 mm thickness under spontaneous change pressure within the range from 1.4 to 0.28 MPa occurred after 1.6 mln oscillations. Under constant 1.4 MPa pressure that corresponding to 990 N load on knee joint the total loss of cartilage was noted after 290000 oscillations, but under constant 3 MPa - after 207000 oscillations.[Гаврюшенко Н.С.
