[DESCRIPTION]: The data comprise finite element input files for 5 ankles at different time points (total 18 specimen-specific models derived from clinical MRI) including cysts or considered intact.
[ETHICAL APPROVAL]: The underlying imaging data has been collected part of a LASERHAEM clinical study led by Dr Wilkins (associated paper co-author, ethics MREC16-087). Using the anonymous images for this research has received local ethical approval (MEEC 18-022), including authorisation to share any derived data openly.

[CONTENT AND SPECIMEN INFORMATION]:
The data comprise finite element input files for 5 ankles at different time points (total 18 specimen-specific models derived from clinical MRI) including cysts or considered intact.
Additional 6 models are used to assess the effect of cyst depth (offset sub-study, baseline geometry is ankle 1, timepoint 7, intact model)

Input files are named as "ankle#_model#_cyst.inp" or "ankle#_model#_intact.inp"; the offset study input files are called "Cystoffset_#mm.inp" (cyst depth, in mm, by 0, 1, 1.5, 2, 2.5, 3).
Results reported are cartilage contact pressures (mean and peak values, in MPa) for the talar and tibial cartilage surfaces.
