“…There are several surgical options for the mode and the level of osteotomies. Among those, correction by a single‐level isolated high tibial osteotomy (HTO) in knees with severe varus deformity has been shown to result in non‐anatomical joint line obliquity which induces subsequent problems such as increased shear force at the cartilage [1, 3, 13, 31, 34, 35, 38, 42, 46, 48]. Double‐level osteotomy (DLO) combining a lateral closed‐wedge distal femoral osteotomy (LCW‐DFO) [5, 9] and a medial open‐wedge high tibial osteotomy (MOW‐HTO) [15, 26, 45] was introduced with the intent to anatomically reconstruct the bony geometry and limb alignment [1–3, 31, 38].…”
