Osteoarthritis: Clinical and Experimental Aspects. Martel-Pelletier, J, Henrotin, JY, Pelletier, JP. ![]() Growth factor therapy for osteoarthritis. Associations between pre-operative radiographic changes and outcomes after total knee joint replacement for osteoarthritis. Classifications in brief: Kellgren-Lawrence classification of osteoarthritis. Progression of cartilage damage and meniscal pathology over 30 months is associated with an increase in radiographic tibiofemoral joint space narrowing in persons with knee OA-the MOST study. Computer-assisted joint space area measurement: A new technique in patients with knee osteoarthritis. OARSI Clinical Trials Recommendations: Hip imaging in clinical trials in osteoarthritis. Age-related joint space narrowing independent of the development of osteoarthritis of the shoulder. Kircher J, Kuerner K, Morhard M, Krauspe R, Habermeyer P. Radiographic evaluation of arthritis: degenerative joint disease and variations. Kenilworth, NJ: Merck & Co., Inc.Īmerican Academy of Orthopaedic Surgeons. Modern Radiological Imaging of Osteoarthritis of The Hip Joint With Consideration of Predisposing Conditions. Functional cartilage imaging can verify changes in the biochemical composition of the cartilage before they become morphologically evident.If distinct and left untreated, predisposing conditions (such as femoroacetabular impingement) may lead to early development of osteoarthritis of the hip joint.Magnetic resonance imaging can substantiate the indication of surgery in case of discrepancy between clinical symptoms and radiological findings of the hip joint.Using computed tomography, the amount of acetabular bone stock prior to total hip arthroplasty is assessed in selected patients. ![]() Projection radiography is the method of choice for the diagnostic work-up of osteoarthritis of the hip joint.With high-resolution MR sequences and MR arthrography, the detailed depiction of the thin cartilaginous coating of the hip joint has become quite possible. ![]() ![]() With the increasing number of joint-preserving interventions such as surgical hip luxation and hip joint arthroscopy for treating FAI, high-resolution imaging is gaining further importance for both pre- and postoperative diagnostics because it can accurately recognize early stages of joint damage. Conventional X-rays remain indispensable for the diagnosis of osteoarthritis, while MRI is able to depict additional early symptoms and signs of activity of the disease. Besides established imaging diagnostics of osteoarthritis, this review also outlines new MRI techniques that enable the biochemical analysis of hip joint cartilage and discusses predisposing deformities of the hip joint including femoroacetabular impingement (FAI) with labral pathologies, hip joint dysplasia, malrotation, and, finally, femoral head necrosis, for which early detection and an exact description of the extent and localization of the necrotic area are extremely important. This review article discusses the value of three imaging modalities in the diagnosis of osteoarthritis of the hip joint: projection radiography, computed tomography, and magnetic resonance imaging (MRI). Osteoarthritis is the most common disease of the hip joint in adults and has a high socioeconomic impact.
