Impact of simulated owHTO on mediolateral patellar rotation; boxplots of mean RMSE ranges for comparison of the simulation results of the models with an owHTO of 6–12 mm wedge height and example of an individual lower limb model with native knee model (red line) and an owHTO of 6–12 mm wedge height (other lines) from 5° to 100°; (A) ascending and (B) descending biplanar owHTO cut RMSE, (C) ascending and (D) descending exemplary knee model; owHTO = medial open-wedge high tibial osteotomy, RMSE = root-mean-square error
