Cemented first-time revisions of the femoral component

In a prospective, consecutive study of first-time cemented femoral revisions, 109 hips were evaluated for a minimum of 7 years. There were 87 Charnley (18 standard, 69 long), 21 Spectron (3 standard, 18 long), and 1 Brunswick long-stem arthroplasties. There was an increased risk for rerevision in younger patients (P =.0001) and with use of standard stems (P =.002). Factors of importance for development of mechanical failure were younger age (P =.0001), presence of more pronounced bone defects (P <.005), use of standard stems (P <.0005), and presence of radiolucencies on the postoperative radiographs (Gruen zones 4 and 6) (P <.01). Our results confirm that cemented femoral revisions are a durable option in elderly patients, when improved cementing techniques and long-stem prostheses are used.
