Abstract:
PURPOSE: This study is to establish a detailed anthropometric data of Korean female knee and to compare the data with current total knee prostheses. MATERIALS AND METHODS: 476 consecutive osteoarthritic knees were measured intraoperatively about anteroposterior (AP) dimension of medial and lateral condyle, and mediolateral (ML) dimension of distal femur as well as proximal tibia. Dimensions of 5 total knee arthroplasty (TKA) systems were compared with these measurements. RESULTS: The AP dimension of medial and lateral condyle, and ML dimension of distal femur were 60.3+/-3.5 mm, 60.9+/-3.2 mm and 68.4+/-3.9 mm, respectively. Those of proximal tibia were 47.4+/-2.8 mm, 39.5+/-3.1 mm and 67.4+/-2.9 mm, respectively. Korean femurs below -1 standard deviation (SD) in lateral AP dimension had narrower ML dimension than femoral prostheses. And most femurs above -1 SD in lateral AP dimension had wider ML dimension than femoral prostheses. Korean tibias had wider ML dimension than tibial prostheses. CONCLUSION: Current total knee prostheses had tendency to ML overhang in small femurs and ML undercoverage in other femurs, and tendency to ML undercoverage or posterolateral overhang in tibias. Thus, Korean anthropometric data should be considered in Korean-friendly prostheses.
