♦ Traditionally bearings were made from polyethylene and cobalt chrome. These bearings are still most commonly used for knee replacements. In hip replacements due to osteolysis caused by polyethylene wear alternative material combinations at the bearing surface are used♦ Highly cross linked plastics have been developed and have been shown to reduce ...

Metal-on-metal Bearing Surfaces
Journal of the American Academy of Orthopaedic Surgeons, 2009Metal-on-metal bearing couples remain a popular option in total hip arthroplasty and are the only currently available option for surface replacement arthroplasty. In general, the intermediate-term clinical performance of metal-on-metal bearings has been favorable.

Clinical Orthopaedics and Related Research, 1999
Despite more than 25 years of clinical experience with ceramic materials as bearing surfaces, their role in modern joint replacement surgery remains to be clearly defined. The two primary materials are alumina and zirconia. The application of these materials is primarily as a femoral head bearing surface against polyethylene, but alumina also is used ...

Surface roughness of the proximal and distal bearing surface of mobile bearing total knee prostheses
The Journal of Arthroplasty, 2002Proximal and distal articulations surface roughness measurements were done on 8 mobile bearing knee designs immediately after removal from sterile packaging. Roughness parameters Ra and Rp based on ISO 97, representing mean deviation from the smooth surface line and mean peak to smooth surface line, were recorded using a contact surface profilometer at

Optimal bearing and bearing rate estimator using an ambiguity surface
[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992A method for developing a bearing and bearing rate estimates that have Cramer-Rao bound accuracy near detection levels using a bearing-bearing rate ambiguity surface is presented. The ambiguity surface is generated from averaged line array cross correlation data by integrating according to predefined hypotheses of possible contact motion.
