Modern designs are now contributing to a remarkable renewed interest in total ankle arthroplasty (TAA), but TAA is still not as successful as total hip and total knee arthroplasty . Among the remaining issues there is the design of the prosthesis components, which are often claimed to be 'anatomical' or compatible with the bony and ligament structures. However, very little is reported in the literature about the morphology of the distal tibia and proximal talus. Not a single is dedicated to the ankle morphological parameters in the Chinese population, which are expected to be addressed particularly in prosthesis designs dedicated to meeting the requirements of oriental life style. The purpose of the current study was to bridge the gap.
Mean, standard deviation, maximum, minimum, median values for all 8 measurements of the ankle joint for the 10 subjects analysed
The success of an ankle prosthesis design depends largely on the morphological data from the ankle joints of its targeted population. The measurements in the current study are expected to contribute to the design of surgical instruments and in particular of the dimensions for the different prosthesis component sizes, which were revealed to be under dimensioned. This is particularly true in post-traumatic ankles, where bones are larger than in normal ankles.
