チャンレー式全人工股関節置換術後の5年以上経過成績

抄録

116 total hip replacements were performed for 112 patients in our clinic since 1974. 29 hips in 28 patients with the average age of 58 years old who received Charnleys low friction arthroplasty more than five years ago were reviewed.
In the follow up study, operated hips were evaluated using the scale for osteoarthritis of the hip joint adopted by the Japanese Orthopaedic Association. Radiological examination was performed using postoperative radiological evaluation scale offered by four department of orthopaedic surgery in Japan. Results showed that preoperative total average score of 40.9 points was improved to 84.6 points postoperatively with marked improvement in relief of pain and ability to walk. Radiological loosening was noticed in the acetabular component in two cases and femoal component three cases. Early and late infections and revision were not experienced.
