1. ABOUT THE DATASET -------------------- Title: Stability of Osteochondral Grafts within Porcine Femoral Condyles - experimental, imaging and computational data for preclinical assessment Creator(s): Gavin A Day, Robert J Cooper, Alison C Jones, Marlène Mengoni, Ruth K Wilcox Organisation(s): University of Leeds Rights-holder(s): Gavin Day Publication Year:2022 Description: The dataset contains the raw microCT scan data, computational and experimental test results, and scripts used in the associated paper. Specifically, this is testing data for the bone material property derivation of porcine femoral condyles and stability testing of porcine osteochondral allografts. Example finite element example models are also included, provided in INP format. Cite as: Day GA, Cooper RJ, Jones AC, Mengoni M, Wilcox RK.

PROJECT AND FUNDING INFORMATION ---------------------------------- Title: Optimising knee therapies through improved population stratification and precision of the intervention Dates: 01 Oct 2016 - 30 Sep 2022 Funding organisation: EPSRC Grant no.: EP/P001076/1 4. CONTENTS ----------- File listing - Bone Property Optimisation - Contains the stiffness values of the experimentally tested porcine femoral condyles potted in PMMA and loaded to 1000 N. Stiffness measurements were taken between as the gradient between 200 and 500 N. - Abaqus v.2017 input files are included with boundary conditions matching the experimental setup. These models were run through an optimisation process to determine the material property mappy constant. Segmentation and meshing was conducted using Simpleware ScanIP 2019. - Examples of Interference Fit Limitations - Contains methods of modelling the interference fit between osteochondral grafts and the host bone of the condyle. - Including input files and output, inp and odb respectively, created and solved using abaqus CAE v.2017. Segmentation and meshing was conducted using Simpleware ScanIP 2019. - CF_0_5_P_0_05M_80 - models with an outward radial force applied to the encompassing face of the graft. - sipbplug-linear-123-123 - tests with greyscale material properties and abaqus presfit - nopfit_nopress-force - models without a pressfit or radial force, just graft oversizing, similar to the final modelling approach. - Mesh Density and Element Type Comparisons - Resultant data for the mesh density convergence testing, including the use of homogeneous material properties and quadratic elements. - Results are given in an xlsx file. - Abaqus output databases are also given. - Scan Data - DICOM images for the material property optimisation and the graft stability tests are provided. - Scan settings: XtremeCT, Scanco Medical AG, Switzerland; 82 μm isotropic voxel size: 900 lA, 60 kVp energy and 300 ms exposure. - graft stability / push in testing data includes pre and post test ct scan data. 5.
