This opportunity is particularly appealing for the postreconstruction therapy of many knee traumas. For instance the reconstruction of a knee ligament is frequent among players of many popular sports and ligament breakdowns occur both to professional players and to amateurs. 4. Conclusions A procedure has been presented that leads to design novel knee orthoses inspired by equivalent spatial mechanisms ESM proposed recently in the literature for replicating the human knee passive motion. In particular in-vivo measurement issues of knee motion as well as techniques for the synthesis of ESM have been addressed. Finally guidelines for the design of new orthoses that can reestablish either the complete functionality of the knee articulation or selectively only the functionality of the injured knee structures have been presented.
