Three subject-specific human tibiofemoral joint finite element models: complete three-dimensional imaging (CT & MR), experimental validation and modelling dataset

This dataset includes the experimental data, three-dimensional imaging, computational models and study data from work validating three subject-specific human tibiofemoral joint finite element models. This work forms part of a wider project developing in vitro and in silico pre-clinical testing methods for tissue preserving treatments of the knee joint. The aim of the related study was to provide validation of contact mechanics outputs for specimen-specific tibiofemoral joint models and specifically investigate the need for subject-specific shape representation for the cartilage and meniscus tissues. The dataset provides a complete set of imaging, experimental and computational data for replication of the study. To maximum the potential for re-use the dataset includes imaging and experimental data, which was collected alongside the immediate study data, but not used in that work. Magnetic resonance imaging of the knee joints in their intact state is included, using eight different imaging sequences. Micro computed tomography imaging of the distal femur and proximal tibia after dissection and testing are also provided for all three knee joints. The experimental data includes pressure sensor measurements taken from the tibial cartilage surface at multiple knee joint flexion angles and photographs taken during dissection, potting and loading of the joints. The computational models are provided for all cases performed for the validation and sensitivity testing study, along with the associated results.
