The evaluation of the knee joint behaviour is of great interest for medicine. A new rig to test knees in vitro in loaded and unloaded conditions is presented in this paper. Its loading system based on a cable-driven parallel manipulator allows the application of general loads typical of common daily activities. Its force-control permits the evaluation of the joint natural response to the loads in terms of movement, measured thanks to a stereophotogrammetric system. In addition, the principal muscles that control the knee flexion and extension can be simulated and their contributions to the joint equilibrium can be evaluated thanks to a dedicated control system. The rig is an evolution of a previously presented version, of which it preserves the low cost and simplicity, together with the versatility and accuracy.

Abstract

The evaluation of the knee joint behaviour is of great interest for medicine. A new rig to test knees in vitro in loaded and unloaded conditions is presented in this paper. Its loading system based on a cable-driven parallel manipulator allows the application of general loads typical of common daily activities. Its force-control permits the evaluation of the joint natural response to the loads in terms of movement, measured thanks to a stereophotogrammetric system. In addition, the principal muscles that control the knee flexion and extension can be simulated and their contributions to the joint equilibrium can be evaluated thanks to a dedicated control system. The rig is an evolution of a previously presented version, of which it preserves the low cost and simplicity, together with the versatility and accuracy.
