Abstract

Aim: Assessement of knee injuries on magnetic resonance imaging to serve the classification, prognosis and selection of appropriate treatment methods for patients with knee osteoarthritis. Objects and methods: 60 knee joints - 30 patients, 26 female, 4 male, mean age 58.63 ± 11.11 years, were diagnosed degenerative according to American Society of Rheumatology (ACR), stage II - III according to Kellgren and Lawrenc. All had a full clinical examination and magnetic resonance imaging of both knees. The metrics are measured on the machine's software. Results: The articular cartilage at the inside condyle was thinner (1.35±0.14 mm) than the intercondylar (1.57±0.11mm) and outside condyle (1.40±0. 10mm). The cartilage thickness of the patellar joint was 1.56 ± 0.09 mm . Injury to meniscus is mainly internal meniscus: tear 41.67%), convex 48.3%. 100% have the knee effusion on magnetic resonance. Edema of the femoral bone accounts for 80%, the tibia 60% and the patella only 36.67%. Conclusion: Osteoarthritis imaging of the knee on magnetic resonance was mainly eroding the cartilage layer at the inside condyle, outside condyle, intercondylar and patellar joint. Injury to the meniscus was mainly the internal meniscus. The edema of the femoral and tibial bones was predominant.
