The purpose of this study was to analyze the intermediate to long-term results of primary total hip arthroplasties with a Harris-Galante prosthesis.

Among 97 consecutive total hip replacements with Harris-Galante prosthesis in 85 patients, 76 hips in 67 patients were evaluated clinically and roentgenographically. The mean follow-up was for 10.1 years (range 6.2-13 years). Clinical and radiographic evaluations including osteolysis, stability of prosthesis, and wear of polyethylene were performed. Statistical analysis was conducted to find the relevant factors influencing osteolysis. The survivorship of overall and each acetabular and femoral component was analyzed by Kaplan-Meier method.

The Harris hip score averaged 44 points at preoperatively and improved to 89 points at the most recent follow-up. Pelvic osteol-ysis was found in 3 hips (4%) and femoral osteolysis was found in 32 (42%). The linear polyethylene wear rate was averaged 0.13 mm/year. Nine femoral components and two acetabular components were revised. There were 2 recurrent dislocations, 3 periprosthetic fractures and 4 infections. The probability of survival of the femoral and acetabular component at a mean 10 years was 81% (range 71- 93%) and 96% (range 91-100%) by the Kaplan-Meier method.

The intermediate to long-term follow up of primary total hip arthroplasty with Harris-Galante prosthesis revealed a low failure rate of acetabular component and a relatively high failure rate of the femoral component which was usually related with loosening and osteolysis.
