Bilateral cemented and cementless total hip arthroplasty

Abstract

A subjective, clinical, and radiographic comparison was made between 140 primary cemented and cementless femoral components in 70 patients <50 years old who underwent bilateral simultaneous total hip arthroplasty. The average duration of follow-up was 7.8 years (range, 7-9 years). Hip scores were similar in both groups at the final follow-up. The prevalence of transitory thigh pain was 17% in the cementless group and 3% in the cemented group. No hip had subsidence or aseptic loosening of the acetabular or femoral components in either group. One cemented hip was revised for late infection, and 1 cementless hip was revised for recurrent dislocation. There was no difference in the incidence of osteolysis in the femur (9% in the cemented hip vs 13% in the cementless hip) and acetabulum (9% each) between the groups.
