Abstract

Retrieval analysis is an efficient means of monitoring and evaluating the problems associated with total joint replacements. In 5 years, 130 prostheses have been collected from 8 hospitals in the Chicago area, including 75 hips and 52 knees. All data are summarized and coded for computer analysis. Total hip replacements are being removed at a relatively constant rate with no evidence of an increase in removal with time. In contrast, the majority of total knee replacements collected were removed within 3 years of the original surgery. Fractured and cracked components appear to be almost always associated with loosening. Unlike most other TJR components which usually debond at the bone-cement interface, femoral stems, when loosened, generally debond at the cement-component interface. Such debonding may ultimately lead to gross component loosening.
