Abstract

The authors analyzed 200 uncemented hip prostheses that were retrieved. They determined the type and extent of host-implant interfaces, but found little correlation between subjective pain relief and the histology of the interfaces. Wear debris, bone resorption and looseness were related to pain, although even with these the relationship was not statistically significant.
