Recently, a Total Ankle Arthroplasty (TAA) has been commonly used when no other options are available for patients with severe arthritis at the ankle joint. But bone resorption, aseptic loosening, instability, malalignment and fractures are generally known as the main reasons of TAA failures. Those TAA which have been designed up until now are generally based on the morphological and kinesiological characteristics of the ankle joint. They are adjusted by the ankle joint size of Westerners, although both the morphological and mechanical (strength) characteristics of the ankle joints of Asian are important in the development of a TAA suitable to Asians. Little information about the morphological and mechanical characteristics of the ankle joint of Asians is available for the development of a TAA suitable to Asians. The purpose of this study was, therefore, to analyze the morphological and mechanical characteristics of the ankle joints of Asians. Computed tomography data obtained from 50 patients (mean age: 64.14 ± 9.34 years) were analyzed.
