Fig. 4From: Analysis of the effect of tibial torsion on tibial osteotomy in knee arthroplasty using a three-dimensional computed tomography-based modelling techniqueFor the postoperative valgus group, the postoperative prosthesis placement deviation angle of the alignment by the traditional extramedullary positioning system method were improved by reference to the simulated osteotomy of midtibial medullary cavity alignment deviation angle. For the postoperative varus group, improvement was not obviousBack to article page
