Magnetic Resonance Imaging in the Diagnosis of Traumatic Injuries Knee Joint

Purpose : verification of reliability of MRI signs of damage to the structures of the knee joint in comparison with the data of arthroscopy knee joints. Materials and methods . 59 patients were examined (59 knee joints: 41 right (69.5%) and 18 left (30.5%)) with various knee injuries, aged 17 to 49 years (mean age 33.6 years). All patients underwent magnetic resonance imaging and medical diagnostic arthroscopy. Results . The sensitivity of the MRI to the diagnosis of meniscus ruptures was highest: 91.7% for the lateral meniscus and 95.4% for the medial meniscus. At the same time, in the diagnosis of anterior cruciate ligament ruptures, the MRI examination does not have such a high sensitivity (88.2%). In addition to the above features, MRI provides the ability to determine the damage to bone and cartilage structures. And also according to MRT it is possible to determine the plan of surgical intervention for tears of meniscuses and cruciate ligaments. Conclusion . The obtained data confirm sufficient efficiency of MRI for diagnostics of damages of knee joint structures. Further improvement of methods and increase in experience of interpretation of images will probably reduce amount of false positive and false-negative results in the future.
