Q-Angle is an important biomechanical factor in assessing the knee joint function. Primary knee osteoarthritis (KOA) is more common in females owing to many factors including increased Q-Angle. Studying the complex biomechanics of the knee joint is essential to diagnose and hence properly treating joint pathology conservatively.
Aim of the work
The aim of this work was to study the relation between Q-Angle and clinical, radiographic and musculoskeletal ultrasonographic (US) findings in female patients with symptomatic primary KOA.
Patients and Methods:
This study had included twenty-five female patients with a mean age of 55.7±4.01 years ranged from 47 to 62 years, collected between June 2018 and October 2019, fulfilling the American College of Rheumatology (ACR) criteria for KOA. Patients were clinically assessed with calculation of the Western Ontario and McMaster Universities Arthritis (WOMAC) index as a functional score. They underwent knee musculoskeletal US examination for evaluation of medial, lateral and inter-condylar distal femoral cartilage thickness and grading. Also conventional radiography of knees were scored using the Kellgren-Lawrence (K-L) grading scale. Spearman's rho was used to assess the association between Q-Angle value and clinical, functional, radiographic and US findings.
