Abstract
|
|
|
Purpose: The purpose of this study is to report on the clinical results of more than 10 years of follow-up after ceramic articulation total hip arthroplasty in patients younger than 50 years old who had reported a result of short-term follow-up.
Materials and Methods: We studied 25 patients who underwent cementless THA using ceramic on ceramic articulation between Jan 1998 and Dec 2001. They were followed up for 2-4 years, with good results, and could be followed up for more than 10 years. The evaluation of clinical results included Harris hip score (HHS) and occurrence of thigh pain. Radiologic evaluation was based on osteolysis and the stability of components.
Results: The mean HHS improved from 57.7 to 93.3 during the period of 2-4 years of follow-up and 91.0 at more than 10 years of follow-up. Two patients experienced thigh pain during the period of 2-4 years of follow-up and none of the patients had thigh pain at more than 10 years of follow-up. On the last radiographs, stable fixation was observed in all cases, except for one case of ceramic fracture.
Conclusion: Clinical and radiologic observations of cementless ceramic on ceramic articulation THA in active patients younger than 50 years old who reported a favorable short-term result showed a satisfactory long-term result.
