Abstract
This is a retrospective study on the Taranaki experience with the Harris-Galante uncemented total hip joint replacement.
Ninety-six Harris-Galante total hip joint replacements were performed in ninety patients between September 1986 and September 1989. Twenty-nine patients died during the study and thirteen patients left the Taranaki area and were lost to follow-up. This left forty-eight patients (fifty hips) for evaluation with an average follow-up of fourteen years (range, thirteen to sixteen years). Results were analysed by questionnaire, clinical examination and x-rays.
Four hips were revised giving a Kaplan-Meier survivorship analysis of 89% at 14 years. Two femoral component was revised due to aseptic loosening at six and eleven years and two acetabular components were revised at 10 and 11 years due to liner dissociation.
The average Harris Hip score improved from 47 points preoperatively to 90 points at six years follow-up then declined to 83 at 14 years follow-up.
Osteolytic lesions were identified adjacent to 17% of acetabular components at follow-up and all were confined to zone two. Eighty-nine percent of femoral radiographs showed evidence of stress shielding however there were no grade four changes.
Osteolytic lesions were identified adjacent to 17% of femoral components at follow-up and were predominantly seen distally in zones three, four and five.
This study demonstrates satisfactory results for the Harris-Galante 1 total hip joint replacement at fourteen years follow-up. Cases should be kept under annual review to assess for progressive osteolysis, liner dissociation and the need for revision surgery.
