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.
