Design and Evaluation of Ankle Reconstruction
Ankle reconstruction is a fairly new concept and is one of the popular treatment for ankle fractures and arthritis. Ankle reconstruction aims to offer a successful alternative to arthrodesis, the existing mainstay and gold standard surgical procedure for disabling ankle arthritis. The surgeon fits the talus bone of the upper foot and the tibia bone at the end of the lower leg with metal components made of cobalt chromium alloy with pure titanium where they comes in contact with bone. This project focuses on modelling and 3D printing of a prosthetic talocrural joint. The standard sizes of tibia which is the longer base of lower leg and talus being lower part of the ankle joint are observed and modelled accordingly by using CATIA with standard dimensions. The prototype is made with PLA plastic using an FDM Fused Deposition Modelling 3D printer. The analysis test carried on ANSYS by applying human weight on the tibial surface and physical tests are conducted on universal testing machine. The compressing force is applied on the prototype and observed till failure. Results obtained are compared for static position of the foot of both analytical and physical outcomes.
