Abstract
Purpose
The results of ceramic-on-ceramic (CoC) bearing surfaces in primary total hip arthroplasty (THA) were well known. However, it was not known in revision THA. The purpose of this study is to report the results of revision THA with ceramic articulation.
Materials and Methods
112 revision THAs with ceramic articulation were evaluated. The mean age at the time of surgery was 58.3 years (28 to 97). The mean duration of the follow-up periods was 6.4 years (2 to 11.8 years).
Results
The Harris hip scores improved from an average of 79.0 at the index surgery to an average of 91.1 at the last follow-up. (P<0.001) None of hips showed osteolysis or ceramic head fracture. One hip shows aseptic loosening in the acetabular components with squeaking that caused a re-revision. There were nine cases of dislocation. The overall survival rate of the implants was 85.1% (95% confidence interval, 61.7% to 94.0%) at ten years with revision for any reason as the end point.
Conclusion
The ceramic articulation is one of good bearing options for revision THA in patients with a long life expectancy.
