[DESCRIPTION]: 
The data comprises Finite Element model input files for Abaqus 2019 representative of 1 generic tibifemoral condyle and 3 image-specific tibiofemoral joints.
Each of the baseline datasets was extracted from data shared under CC-BY license: 
	- generic model from the open-knee project first generation (https://doi.org/10.18735/b0zv-n395) as used in Meng Q., Fisher J. & Wilcox R.K. (2017). The effects of geometric uncertainties on computational modelling of knee biomechanics. R. Soc. Open Sci. 4, 170670
	- specimen-specific model from the IMBE knee dataset: Cooper R.J., Day G.A., Wijayathunga V.N., Yao J., Mengoni M., Wilcox R.K. & Jones A.C. (2023) Three subject-specific human tibiofemoral joint finite element models: complete three-dimensional imaging (CT & MR), experimental validation and modelling dataset. https://doi.org/10.5518/981
Derived models were generated from the input files to create a total of 40 model instances used in a sensitivity study. The datasets contains derived input files and python scripts to generate the derived models.
The dataset also contains Finite Element outputs of interest for each of the 40 models.

Project part of EPSRC grant "Optimising knee therapies through improved population stratification and precision of the intervention" (EP/P001076/1)
