Hinge Position Dominance Over Osteotomy Inclination in Medial Open-Wedge High Tibial Osteotomy: A Key Factor in Posterior Tibial Slope Changes.

Objective: A medial open-wedge high tibial osteotomy (MOWHTO) may increase the posterior tibial slope (PTS). The purpose of this study was to determine the effect of the osteotomy inclination angle (in the sagittal plane) in combination with different hinge positions (in the transverse plane) on the change in PTS due to a MOWHTO.

Methods: We developed a mathematical approach to determine the effect of the osteotomy inclination angle combined with different hinge positions.

Radiographic Assessment of Bone Union in Proximal Tibia and Distal Femur Osteotomies: A Systematic Review.

Background: Osteotomies around the knee are a well-established treatment option for early and moderate unicompartmental osteoarthritis combined with a lower extremity malalignment. Moreover, osteotomies are often combined with cartilage treatment. Current image-based bone union assessments lack an accepted definition despite widespread use in research and clinical settings.

Primary care for patients with respiratory tract infection before and early on in the COVID-19 pandemic: an observational study in 16 European countries.

Objective: To describe primary health care (consultation characteristics and management) for patients contacting their general practitioner (GP) with a respiratory tract infection (RTI) early on in the COVID-19 pandemic in contrasting European countries, with comparison to prepandemic findings.

Setting: Primary care in 16 countries (79 practices), when no routine SARS-CoV-2 testing was generally available.

Design And Participants: Before (n=4376) and early in the pandemic (n=3301), patients with RTI symptoms were registered in this prospective audit study.
