Gait and other daily activities depend on proper ankle and foot function. In many rheumatic and musculoskeletal conditions, the ankle is a frequently affected joint in both young and older populations, leading to pain, restricted mobility, and a lower quality of life. The difficulty in accessing the ankle and foot anatomically and the lack of adequate training in clinical assessment methods are two factors that contribute to this problem. Although traditional radiography is currently the preferred imaging method in everyday clinical practice for determining ankle involvement, it does not allow for the evaluation of soft tissues. Additional imaging techniques such as ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) may offer more comprehensive data on soft tissue and bone structures. To diagnose and follow up on patients with inflammatory rheumatic and degenerative joint illnesses, ultrasound is particularly well-suited for examining soft tissue structures, such as the joint capsule, tendons, and ligaments.
