The Third Generation Alumina-on-Alumina Bearing Total Hip Arthroplasty in Patients Under the Age of Forty: A Minimum Five-Year Follow Up Study
The Journal of the Korean Orthopaedic Association
Purpose: We investigated the results of the third generation alumina on alumina bearing total hip arthroplasty in patients under the age of forty. Materials and Methods: Fifty patients (57 hips) under the age of forty, who had uncemented total hip arthroplasty using third generation alumina bearing, between April 2000 and March 2006 were observed. The group consisted of 24 men and 26 women. The average age at the operation was 30.3 years (18-39 years). The average follow up period was 8.0 years
... eriod was 8.0 years (5-11 years). The most common cause for surgery was rheumatoid arthritis. We assessed the clinical and radiological results and postoperative complications. Results: The mean Harris hip score at the last follow-up was 96 points on average. There was no inguinal pain. However, there were two hips of which the patient was experiencing thigh pain. One hip with squeaking was observed. We could observe the stable bony fi xation of implants in all hips. There were no aseptic loosening and no osteolysis around the implants. Postoperative complications included one hip with nonunion of trochanteric osteotomy and one hip with dislocation. There were no ceramic fractures, no postoperative infections and no revisions. Conclusion: We observed the favorable clinical and radiographic outcomes of the third generation alumina on alumina total hip arthroplasty in patients under the age of forty. However, in the case of squeaking, a longer term follow-up is needed.
