The Discussion section throws light upon the surgical method of opening wedge high tibial osteotomy (OWHTO), which provides a precise correction of the alignment and maintenance of the correction over time. It further confirms that the defect can be completely filled with this procedure without grafting. The study Concludes that obesity and initial lateral cortex fracture appeared as risk factors for non-consolidation of OWHTO with large correction. Also, OWHTO without graft interposition using 4 holes Puddu plate with wedges can be considered an alternative in the treatment of medial osteoarthrosis of the varus knee, enabling the correction of the deformity and improvement of the clinical picture.

Further comments on the paper

Comments: This continuous retrospective study demonstrates that opening wedge high tibial osteotomy (OWHTO) can be performed without material interposition to fill the defect. Bone union, its complications (delayed union, nonunion) and functional results with this method have been evaluated in this study. Filling up the osteotomy defect with available materials has various disadvantages such as foreign body reaction, degree of resorption, degree of re-population, and donor site complications for the autograft. This study is of significance as with the advent of new implant that can provide stable fixation, achieving opening wedge high tibial osteotomy without filling the defect and letting the replacement of the lost bone material naturally has become possible.
