What works best, a cemented or cementless primary total hip arthroplasty?: minimum 17-year followup of a randomized controlled trial.

ABSTRACT:

Background

Total hip arthroplasty (THA) has been associated with high survival rates, but debate remains concerning the best fixation mode of THA.

Questions/purposes

We conducted a randomized controlled trial (RCT) with 250 patients with a mean age of 64 years between October 1987 and January 1992 to compare the results of cementless and cemented fixation.

Patients and methods

Patients were evaluated for revision of either of the components. One hundred twenty-seven patients had died (51%) and 12 (4.8%) were lost to followup. The minimum 17-year followup data (mean, 20 years; range, 17-21 years) for 52 patients of the cementless group and 41 patients of the cemented group were available for evaluation.

Results

Kaplan-Meier survivorship analysis at 20 years reve
