Abstract:
PURPOSE: This study evaluated the short-term results of ceramic articulation total hip arthroplasty in cementless total hip arthroplasty. MATERIALS AND METHODS: 142 hips were followed-up for more than 2 years after cementless total hip arthroplasty using ceramic-on-ceramic articulation. The mean age and follow-up period was 58.3 years and 3.0 years, respectively. The Harris hip score and postoperative hip pain were analyzed clinically. The radiological results were assessed using various radiological indices. RESULTS: At the last follow-up, the Harris hip score improved from 58.1 points preoperatively to 93.2 points postoperatively. There were 4 cases (2.8%) of significant hip pain. Radiologically, all the stems demonstrated stable fixation. The inclination of the acetabular cup was changed significantly in 2 cases (1.4%), which were diagnosed as being loosened. A radiolucent line was observed around the stem in 9 cases (6.3%), and around the cup in 3 (2.1%). Endosteal new bone formation was observed around the stem in 50 cases (35%), and around the cup in 55 (38.5%). No osteolysis was observed around the stem and the cup. CONCLUSION: The short-term results of ceramic on ceramic articulation hip arthroplasty were excellent without osteolysis.
