Personalized knee prostheses based on articular models to replicate the joint functionality of a patient

The main objective of articular prostheses is to recover the joint mobility and stability after substitution of the patient articular surfaces. Thus, prosthetic surfaces must fulfil dif-ferent tasks: restoring the natural joint behaviour, compensating the function of articular structures removed during the implant, respecting the residual structures. In general, pros-thetic components have default shape and position that often do not allow fulfilment of these tasks. The scope of this study is to propose an approach for the prosthesis design based on the combination of medical images, personalized articular models and 3D print-ing, to obtain morphological and kinematical information of a patient for the development of personalized prostheses.
