Abstract

It can be stated that polyethylene wear can be shown as a problem in long term joint replacement. Metal-on-metal bearings are solving this problem as long term clinical and experimental investigations can demonstrate. To avoid the problem of high friction that was found to be a problem in older series, a new technique called Metasul with smaller diameter was invented. Intermediate results of Weber and our own data are showing promising results giving us the hope to solve the wear induced problem in hip replacement.
