## Abstract Ceramicโonโceramic (CoC) bearings in total hip replacements (THRs) have shown low wear volumes under standard gait in hip simulator studies. However, clinical reports have indicated variations in wear rates and formation of stripeโlike wear area on the ceramic femoral heads. The aim of
Differences between the wear couples metal-on-polyethylene and ceramic-on-ceramic in the stability against dislocation of total hip replacement

## Abstract We investigated articular bearing surfaces retrieved from three patients with ceramicโonโceramic total hip arthroplasties using highโquality alumina. The duration of implantation was 3.5, 3.0, and 2.5 years, respectively. Dislocation of the hip joint after implantation did not occur in
A theoretical relationship was recently proposed relating the wear behavior of polymetric bearing materials articulating against hard counterfaces. 1 This model attempts to predict the influence of surface roughness on wear. Laboratory-based studies have been used to establish the validity of these
