Abstract
The quantitative recovery of polyethylene wear debris is particularly important in the evaluation of the wear of total joint prostheses as it is the only feasible experimental wear parameter and also because of the clinical significance of the rate of release of the debris into the surrounding tissues. A method has been developed to recover the debris from the synovial fluid or serum in the joint; it consists in essence of chemical digestion, filtration and stereological evaluation of the debris volume. This method separates the polyethylene debris from all the other suspended solids present in the joint fluid and can be reliably and reproducibly calibrated. It has revealed that gross differences exist in the wear rates of commercially available total hip prostheses.
