COMPARISON OF CEMENTED AND CEMENTLESS TOTAL HIP-ARTHROPLASTY IN PATIENTS WITH BILATERAL HIP ARTHROPLASTIES

A consecutive series of 36 patients underwent primary cemented total h ip arthroplasty followed by primary cementless total hip arthroplasty of the contralateral hip. Clinical pain scores between the cementless and cemented hips were not different. Subjectively, patients either ha d no preference or preferred the cementless side. Comparison of result s in the same patient eliminates variability introduced by differences in sex, weight, comorbidities, bone quality and activity level. Contr ol of these factors permits more meaningful comparison of the type of fixation.
