To compare the mechanical safety of a new personalised 3D printed high tibial osteotomy (HTO) device with an existing generic device, a novel case-control in silico virtual clinical trial was conducted (ClinicalTrial.gov NCT03419598). Twenty-eight knee osteoarthritis patients underwent CT scanning to create a virtual cohort; the cohort was duplicated to form two arms, Generic and Personalised, on which virtual HTO was performed. Finite element analysis was performed to calculate the stresses in the plates arising from simulated physiological activities at three healing stages, simulating 2, 4 and 12 weeks after surgery.
The dataset includes the demographic information of the subjects, the applied loads, the summarised output data from the finite element models, namely the maximum Von Mises stress (MPa) in the plate and the maximum Von Mises strain (unitless) in the tibial bone adjacent to the screws holding the plate to the tibia.
