Distal femoral osteotomy (DFO) is a valid option for the treatment of young and active patients with lateral compartment osteoarthritis/overload and valgus malalignment. DFOs can be performed with a closing wedge or opening wedge technique. Lateral opening wedge DFO is usually preferred for smaller corrections, whereas medial closing wedge for larger corrections and in patients with high risk of nonunion. This article describes the relevant aspects regarding lateral opening wedge DFO, including patient selection, preoperative planning, surgical technique, results, and complications.

Association Between Joint Line Convergence Angle and Patient-Reported Outcomes of Opening-Wedge High Tibial Osteotomy.
Am J Sports Med

Department of Orthopaedic Surgery, Hirosaki University Graduate School of Medicine, Hirosaki, Japan.
Background: A larger joint line convergence angle (JLCA) increases the stress load on the medial compartment. Few reports, however, have discussed the effect of the JLCA on the cartilage status and clinical outcomes after opening-wedge high tibial osteotomy (OWHTO).
Purpose/hypothesis: To reveal the effect of the JLCA on clinical results after OWHTO.
Purpose: Hinge fractures show a relatively high incidence in varus and valgus distal femoral osteotomy (DFO) and can lead to delayed- or non-union. Another observed complication of a hinge fracture is an unintentional change of the postoperative femoral torsion of up to + 9.5° in conventionally performed DFO.

Categorization of alignment into phenotypes can be useful for predicting and analyzing postoperative alignment changes after opening-wedge high tibial osteotomy (OWHTO). The purposes of this study were (1) to develop a machine learning model for the predicting the Coronal Plane Alignment of the Knee (CPAK) phenotypes of final alignment after OWHTO, and (2) to analyze predictive factors for final alignment phenotypes. Data were retrospectively collected from 163 knees that underwent OWHTO between March 2014 and December 2019.

Background And Objective: Osteoarthritis is a widespread and debilitating condition, particularly affecting the medial compartment of knee joint due to varus knee deformities. Medial opening wedge high tibial osteotomy (MOWHTO) has emerged as an effective treatment, but it comes with challenges like fractures, correction loss, and nonunion, leading to unsatisfactory results in up to 26 % of patients. In response, our study explores the potential of a bioabsorbable magnesium-based bulk metallic glass composite (MgZnCa BMGC) enriched with molybdenum particles as an innovative solution for MOWHTO.

Purpose: To evaluate the radiological and clinical outcomes in two patient groups: first, varus aligned medial meniscus posterior root tear (MMPRT) patients who underwent posteromedial open wedge high tibial osteotomy (PMOWHTO) and simultaneous root repair; second, patients with varus medial knee osteoarthritis without MMPRT who underwent PMOWHTO.
Methods: Patients had MMPRT repair concomitant with PMOWHTO and varus medial knee osteoarthritis without concomitant root tear patients who underwent PMOWHTO and were reviewed. Radiographic parameters, medial meniscus extrusion (MME) and Knee Society Scores [KSSs, including the following subscores: knee score (KS) and knee function score (KFS)] were evaluated.
