No consensus exists on how to model human articulations within musculoskeletal models (MSKM). We propose to evaluate a joint model based on their anatomical consistency (AC), i.e. by quantifying ligament and cartilage deformation associated to its motion: to be consistent with articular physiology this deformation should be minimum. We compared AC of three ankle joint models with increasing personalisation and showed that a higher personalisation better complies with the expected physiological behaviour.
