【 摘 要 】

Category:Ankle ArthritisIntroduction/Purpose:Ceramic 2-component total ankle prosthesis, TNK-Ankle, has been used clinically as standard prosthesis in severe ankle osteoarthritis or rheumatoid arthritis for long years in Japan. Two-component prosthesis would require more precise replacing because of more constraint than mobile type. We would report the outcomes of total ankle arthroplasty (TAA) with TNK-Ankle investigated radiographically using custom image measurement software and compared with clinical scores.Methods:Twenty four cases of total ankle arthroplasty with TNK-Ankle for osteoarthritis in stage 3b and 4 operated by an expert surgeon from 2009 to 2013 have investigated on X-rays of preoperative unaffected and postoperative affected ankles. Clinical outcomes by JSSF score based on AOFAS score and SAFE-Q, patient-based questionnaire, were compared with radiographic measurements. Image analysis performed with custom OpenCV software programmed for this study. This could match translucent X-ray imag...
