Where this comes from

Abstract

Modular bipolar prostheses were developed to address the problems of loosening, cartilage wear, and protrusio which were seen with single unit endoprostheses. Modular unipolar prostheses address many of these problems and are significantly less expensive than the bipolar prosthesis. Recent data suggest that use of the modular unipolar prosthesis is indicated in elderly patients with low demands.
