Examination of SARS-CoV-2 RNA in joint synovial fluid of patients with COVID-19 and acute knee arthritis.

Background: It has not yet been fully established that there is coronavirus disease 2019 (COVID-19) involvement in the synovial fluid and it remains a topic of debate.

Objective: The aim of this study was to evaluate the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in knee joint synovial fluid of patients with COVID-19.

Methods: This retrospective study was conducted with an initial screening of patients who were admitted to a tertiary pandemic hospital due to COVID-19 symptoms, and underwent treatment for COVID-19 between March and June 2020.

Evaluation of the relationship between stiffness and thickness of the sciatic nerve and clinical outcomes after total hip arthroplasty: A prospective casecontrolled study.

Objective: The aim of this study was to conduct a sonographic assessment of sciatic nerve thickness and stiffness following total hip arthroplasty (THA) and to determine the relationship between sonographic characteristics of the sciatic nerve and clinical outcomes.

Methods: This prospective study included patients undergoing primary cementless THA due to hip osteoarthritis between January 2018 and January 2019 in a tertiary-level hospital. The thickness, strain elastography, strain ratio (SR), and shear wave elastography (SWE) of the sciatic nerve were measured.

Does Obesity Have an Effect on the Outcomes of Unicondylar Knee Arthroplasty in Patients with Isolated Medial Gonarthrosis?

PURPOSE OF THE STUDY The aim of this study was to evaluate and compare the functional outcomes and complication rates of patients in the midterm follow-up period when patients applied with medial unicondylar knee arthroplasty (UKA) were grouped according to Body Mass Index (BMI) values MATERIAL AND METHODS The study included 125 patients applied with medial UKA between December 2013 and December 2017 because of isolated medial compartment gonarthrosis and completed at least 2 years of follow-up. The patients were separated into three groups: non-obese with a BMI < 30 kg/m2, obese with BMI of 30-39 kg/m2, and morbidly obese (BMI ≥ 40 kg/m2). The implants used in all surgeries were cemented fixed-bearing implants.

Epiphysis Salvage Reconstruction and Associated Complications Following Tumor Resections in Skeletally Immature Patients.

The purpose of this study was to discuss the epiphysis salvage reconstruction procedure outcomes and complications in skeletally immature patients. The study included 12 patients with pediatric malignant tumors (osteosarcoma, Ewing's sarcoma) located close to the epiphysis, who underwent epiphyseal-preservation surgery with vascularized fibula in the plastic surgery and orthopedics and traumatology clinic between January 2008 and November 2018. The study was designed retrospectively.

Ultrasonographic measurement of diaphragm thickness in patients with severe thoracic scoliosis.

Purpose: This study aimed to measure diaphragm thickness using ultrasound in adult patients with severe idiopathic scoliosis.

Methods: This prospective case-control study included patients with severe idiopathic scoliosis and a healthy control group. The control and patient groups' demographic features, pulmonary function tests, diaphragm thickness, and thickening fraction measured using ultrasonography were compared.
