    The distribution in joint recesses and adjacent synovial compartments of loose bodies determined on MR and CT arthrographies of ankle joint

    Loose bodies (LBs) are intraarticular free bodies that result from various pathological processes and cause synovial inflammation. Timely and complete identifica-tion of LBs is important for appropriate treatment and prevention of possible complications such as osteoar-thritis. LBs in the ankle joint can reach all the compart-ments that are adjacent to the joint via physiological or pathological connections. The presence, localisation, and number of LBs in the ankle joint and adjacent synovial compartments can be optimally evaluated using high -resolution magnetic resonance arthrography (MRA) and computed tomography arthrography (CTA). On this review article, we aimed to determine the LB location and distribution using high-resolution MRA and CTA of the ankle joint, and to demonstrate that it may be used as a complementary examination to guide interventional arthroscopy in difficult- to- reach areas during treatment. Advances in knowledge Loose bodies (LBs) are intraar-ticular free bodies and may cause synovial inflammation. Accurate and complete determination of the number and location of LBs before surgery are very important for effective treatment. The location, number and distribution of LBs in the ankle joint may be determined successfully by high-resolution magnetic resonance arthrography (MRA) and computed tomography arthrography (CTA). For this purpose, MRA and CTA may increase the diag-nostic and therapeutic success of the arthroscopy.
