Survival of cemented total hip replacements.
A Kaplan-Meier survival analysis of 240 Charnley, 149 Mueller (Depuy, Warsaw, IN), 576 Trapezoidal 28 (Zimmer, Warsaw, IN), and 100 Miami Orthopaedic Surgical Clinics (Biomet, Warsaw, IN) cemented total hip replacements with all polyethylene acetabular components, performed by the senior author (M.A.R.) should be the basis that all noncemented total hip replacements must exceed to be a reasonable alternative. Failure, ie, revision and a loose prosthesis, shows that 80%, 61%, and 63% of the Charnley, Mueller, and Trapezoidal 28, respectively, survive longer than 15 years.  The Miami Orthopaedic Surgical Clinics prosthesis, which uses current cement technology, has been observed for only 8 years.  Despite the fact that there are no differences noted between all four prostheses at 8 years, more time is needed to judge the usefulness of current cement technology.
