Abstract:
Total hip arthroplasty has been associated with excellent implant survival rates, but debate remains concerning the best fixation method for the components. A randomized controlled trial, which included 250 patients (mean age, sixty-four years) with osteoarthritis who were managed with total hip arthroplasty between October 1987 and January 1992, was conducted to compare the results of fixation with and without cement. Patients were followed for a mean of twenty years (range, seventeen to twenty-one years). Kaplan-Meier survivorship analysis at twenty years revealed significantly lower survival rates for cemented implants as compared with cementless implants. The cementless tapered stem had an extremely good survival rate of 99%. Radiographs showed evidence of mild stress-shielding around 95% of the cemented stems and 88% of the cementless stems; stress-shielding of grade 3 or greater was seen around the remaining 12% of the cementless stems.
