The surgical accuracy of knee osteotomy

Abstract

Osteotomy around the knee is a versatile operation, where restoration of lower limb alignment is beneficial for a range of pathologies. A paper from Norway in this issue describes good functional results with mid term follow-up [ [1] Ekeland A. Nerhus T.K. Dimmen S. Thornes E. Heir S. Good functional results following high tibial opening-wedge osteotomy of knees with medial osteoarthritis: A prospective study with a mean of 8.3years of follow-up. The Knee. 2017; 24: 379-388https://doi.org/10.1016/j.knee.2016.12.005 Abstract Full Text Full Text PDF Scopus (25) Google Scholar ]. Although more commonly used to treat varus and valgus deformities in the coronal plane, it has now been adapted to remedy misalignment in the sagittal plane [ 2 Kim T.W. Lee S. Yoon J.-R. Han H.-S.

Experimental 3D modelling has been applied to high tibial osteotomy using porcine bone [ [4] Kwun J.-D. Kim H.-J. Park J. Park I.-H. Kyung H.-S.
