Ultrasound reveals hidden muscle clues in knee arthritis

This observational study looks at how the quality of thigh muscles relates to pain, physical function, and quality of life in women with knee osteoarthritis. Researchers will use a non-invasive ultrasound to measure muscle thickness and texture during a simple leg exercise. Participants also fill out standard questionnaires about their symptoms and daily activities. The goal is to better understand how muscle health impacts the experience of knee arthritis.
