The purpose of this study is to evaluate the functional and radiographical results in patients younger than 30 years who underwent cementless third generation ceramic-on-ceramic total hip arthroplasty (THA) for avascular necrosis (AVN) of femoral head. Forty one patients (55 hips) with a minimum 4-year follow-up were included in this study. There were 26 men and 15 women with a mean age of 25.6 years (range, 16 to 29 years). The average duration of follow-up was 5.7 years (range, 4.0 to 6.5 years). All surgeries were done by a single hip surgeon and third generation ceramic-on-ceramic articulation was used. Functional results were measured by Harris hip score (HHS) and WOMAC score. Radiographic evaluation was assessed for loosening and osteolysis according to Gruen's and Delee and Charnley's criteria.Purpose
