Two techniques of closed wedge osteotomy of the proximal tibia in 132 cases using external fixation device were compared retrospectively for neurological complication rate. While in group 1 (n = 89) wedge osteotomy was performed conventionally using an oscillating saw, in group 2 (n = 43) osteotomy was done with consecutive drill holes of increasing diameter followed by osteoclasis. Neurological complications in group 1 were found postoperatively 15.7% (transient) and after 7 months follow-up time in 12.4% (persistent), in group 2 14% transient and 4.7% persistent neurological deficits were registered. The lower complication rate in group 2 is due to the reduction of postoperative tibialis anterior syndrome (type B lesions). No differences for type C lesions (extension deficit of D1) were found. No complete peroneal palsy (type A) occurred in either group. The authors conclude that reduction of neurological complications in group 2 is related to the less extensive approach of the proposed technique.

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

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.

Recent findings suggest a slight but significant reduction of the medial proximal tibial angle (MPTA) resulting in a varus knee where the sagittal osteotomy plane is based on a total of two guide wires defining the osteotomy wedge without respecting the frontal plane. We hypothesize that the placement of a total of four guide wires intraoperatively can reduce the influence on the MPTA.
