Abstract

This dataset contains the experimental measurements used to derive and validate a continuous non-linear map of the human knee response to load. Data were collected in vitro from six fresh-frozen cadaveric lower limbs obtained from five donors, using a custom cable-driven loading rig and a stereophotogrammetric acquisition system. For each specimen, tibiofemoral kinematics were recorded continuously across the full flexion range under unloaded conditions and under multiple monoaxial loading cases, including forces along the anterior-posterior, proximal-distal, and medial-lateral directions and torques about the abduction-adduction and internal-external axes. Additional combined-loading experiments are included for validation. The dataset supports the reconstruction of natural knee motion and load-induced deformations as functions of flexion angle, load magnitude, and load direction, and can be used for kinematic load-dependent mapping, multi-body and musculoskeletal modelling, model calibration, and validation studies in joint biomechanics. This dataset updates the previous contribution, “In-Vitro Tibiofemoral Kinematics Dataset Under External Loading: Experimental Dataset for a Continuous Nonlinear Knee Compliance Map”, available in the AMSActa archive. The changes are limited to notation updates and the addition of references to provide further clarification on the experimental apparatus and setup. No modifications were made to the underlying data with respect to the cited contribution.
