Appropriate Treatment

Loose bodies (LBs) are intraarticular free bodies that result from various pathological processes and cause synovial inflammation. Timely and complete identification of LBs is important for appropriate treatment and prevention of possible complications such as osteoarthritis. LBs in the ankle joint can reach all the compartments 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 intraarticular 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 diagnostic and therapeutic success of the arthroscopy.

Purpose The aim of this study was to assess the diagnostic accuracy of magnetic resonance arthrography (MRA) in the detection of intra-articular lesions of the hip in patients affected by femoroacetabular impingement (FAI) by using arthroscopy as reference standard. Methods Twenty-nine consecutive hip arthroscopies performed in 24 patients were considered for the study. Patients had a mean age of 38.3 years. Ultrasound-guided 1.5-T MRA was performed with precontrast short tau inversion recovery, T1-weighted and PD coronal, T1-weighted, and T2-weighted axial with 3-mm-thick slice sequences, and postcontrast T1-weighted fat saturation MRA (Fat-SAT) axial, coronal and oblique sagittal, and T1-weighted Vibe 3D coronal sequences with MPR sagittal, axial, and radial reconstructions with 2-mm-thick slice and coronal density protonil (DP) Fat-SAT. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of MRA were evaluated by comparison arthroscopy for the following intra-articular findings: acetabular and femoral chondral lesions, labral degeneration, labral tears, synovitis, ligamentum teres (LT) tears, CAM lesions, pincer lesions, loose bodies, and osteophytes. Results An absolute per cent agreement (100%) was observed for all the variables in the assessment of CAM lesions. Sensitivity, specificity, PPV, and NPV of MRA were 100, 68.4, 72.7, and 100%, respectively, for acetabular chondral lesions; 100, 50, 47.3, and 100%, respectively, for femoral chondral lesions; 33, 85, 20, and 91.6%, respectively, for labral tears; 95, 71, 91.3, and 83.3%, respectively, for labral degeneration; 100, 88, 57.1, and 100%, respectively, for LT tears; 33.3, 85, 50, and 73.9%, respectively, for pincer lesions; 50, 96, 66.6, and 92.3%, respectively, for intra-articular loose bodies; and 100, 73.9, 50, and 100%, respectively, for osteophytes. Conclusion MRA may play an important role in detecting intra-articular lesions associated with FAI. This might be helpful for the preoperative planning before hip arthroscopy. Level of Evidence This is a Level 2, diagnostic accuracy study compared with gold standard.
