Aims

The aim of this study was to compare the survivorship and radiographic outcomes at ten-year follow-up of three prospective consecutive series of patients each of which received a different design of cementless femoral components for total hip arthroplasty (THA).

Patients and Methods

In Cohort 1, 91 consecutive patients (100 hips) underwent THA with a cementless porous-coated anatomic femoral stem (PCA) between October 1983 and January 1986. In Cohort 2, 86 consecutive patients (100 hips) underwent THA with an extensively porous-coated cementless femoral stem (Prodigy) between June 1994 and October 1997. In Cohort 3, 88 consecutive patients (100 hips) underwent THA with a proximally porous-coated triple-tapered cementless stem (Summit) between April 2002 and October 2003. All three groups underwent prospective clinical and radiographic evaluation.
