Purpose: To evaluate the 8-year follow up results of the clinical and radiographic of the cementless total hip arthroplasty using the Osteonics<SUP>®</SUP> system with ceramic-on-ceramic articulation on a retrospective basis. Materials and Methods: Between March 1999 and February 2000, 31 primary total hip arthroplasties were performed in 27 patients using the cementless Osteonics<SUP>®</SUP> system. The mean follow-up period was 101 months (96-107 months). The mean age at surgery was 56.5 years of age (28-62 years). Preoperative diagnoses were the following in the 27 patients: 5 cases of primary osteoarthritis, 15 cases of avascular necrosis, and 7 cases of secondary osteoarthritis. The clinical results were evaluated using the Harris hip score and radiographic evaluation was done in terms of the fixation of components, the prevalence of osteolysis, and wear of ceramics. Results: The mean preoperative Harris hip score at was the most recent follow-up was 91. Complications were calcar fracture in 8 cases, posterior dislocation in 2 cases, continuous thigh pain in 2 cases, squeaking sound in 3 cases, and limping gait lasting at least 1-year post operation in 6 cases. All cases had fixation by bony ingrowth was and there was no migration of acetabular cups nor osteolysis. There was no loosening of the femoral stem. It was not possible to measure ceramic wear and there were no ceramic fractures. Conclusion: At the 8-year follow-up, results of the cementless total hip arthroplasty using the Osteonics<SUP>®</SUP> system with ceramic-on-ceramic articulation demonstrated favorable results of osseointegration of the components and unmeasurable ceramic wear. However, longer-term-follow up was necessary. We believe that further study is required to determine the high incidence of squeaking.
