This project has two objectives: 1. to optimise the surface geometry of an existing unicondylar knee prosthesis in order to enable natural knee kinematic 2. to model and validate a generally valid parameter model of the knee ligaments in FEA.

In the development process, both experimental robot-supported tests on human specimens and calibrated FE models are used.
