The Journal of Arthroplasty
We report the first long-term results of a prospective cohort study after total hip arthroplasty using the cementless Bicontact hip stem. Between 1987 and 1990, 250 total hip replacements in 236 patients were performed using the cementless Bicontact hip stem. The average follow-up was 22.8 years (20.4 to 24.8) and average age at index surgery 58.1 years. 81 patients deceased and 9 were lost to follow-up. We noted 11 stem revisions revealing an overall Kaplan Meier survival rate of 95,0% (CI 95%: 91,1-97,2%). The average Harris Hip Score revealed 81 points (range 24 to 93). The Bicontact hip stem demonstrated high survival rates despite high ages and osteopenic changes, which are equivalent to other long-term reports of cementless stem fixation.
