Loosening of the bearing component of TAR became main cause to implant failure due to the polyethylene wear particles induced osteolysis. This paper introduces a wear prediction on effect of radial and thickness of polyethylene towards wear generation on TAR. The joint reaction force profile at ankle joint applied 25 discrete instants during stance phase of a gait cycle. The sliding distance was obtained from predominate motions of plantar/dorsi flexion. The value of linear wear depth and volumetric wear is in agreement with experimental testing was 0.01614 mm per million cycles and 30.5 mm3, respectively.
