Determination of MRT and US sensitivity and specificity for examination of patients with the knee element injuries

Purpose. To make a comparative analysis of MRT and USE efficiency when revealing pathology of the elements of the knee for its injuries. Materials and Methods. Ultrasound examination and magnetic resonance tomography performed in 85 patients at the age of 14-62 years with the knee element injuries. A comparative analysis of USE and MRT data versus arthroscopy results made in order to calculate the sensitivity and specificity of the techniques. Results. The results demonstrated high percentage of combined injuries of the knee structures (40%) among the subjects examined. USE procedure found to be rather efficient for the diagnostics of isolated injuries of the medial meniscus, while it was little efficient for revealing the injuries of cruciate ligaments, and combined injuries of intraarticular structures. In this case MRT procedure is more informative because it allows rather perfect visualization of both isolated and combined injuries in the acute period of trauma. Conclusion. As the data have shown, it’s necessary to make comprehensive examination in order to reveal pathological changes in the structural elements of the knee injured, as well as to select the tactics of further treatment.
