Abstract
Background: Ultrasound (US) is used as a non-invasive assessment of musculoskeletal system. Recently, many studies have been reported using US to evaluate the meniscal status of the knee joint. The US evaluation of the meniscal position under weight-bearing has been discussed. Objectives: The aim of this study was to diagnose osteoarthritis (OA) of the medial compartment of the knee joint using ultrasound (US). Methods: In a cross-sectional controlled study. The study subjects included 25 patients and 25 controls (88 knees), US was used to evaluate the medial joint space of both knees in complete extension with and without weight bearing. In each patient, the medial radial displacement of the medial meniscus (MRD), the peripheral joint space (PJS) and the size of osteophytes were evaluated. The reproducibility of US in this setting was assessed and the US measurements were compared between patients and controls. The preliminary results have shown the great complementary role of dynamic ultrasonography in the diagnosis of osteoarthritis (OA) of the knee joint
