Comparative Study between High Resolution Ultrasound (HRUS)and MRI in Diagnosis of Meniscal and Cruciate Ligaments Injuryof the Knee

Objective: The purpose of this study is to evaluate the role of high resolution ultrasound (HRUS) in comparison to MRI in diagnosis of meniscal and cruciate ligaments injury of the knee. Patients and Methods: In the period from November 2010 to November 2011 a total of 35 persons were examined including 5 cases in control group and 30 cases in patient group. All cases were subjected to high resolution ultrasound and MRI of the knee. We evaluated the menisci, ACL PCL. Results: The study included 30 symptomatic patients with history of acute or chronic knee trauma, 24 males and 6 females. Their ages ranged from 18-35 years. All patients were known or suspected to have knee derangement as a sequalae of trauma. All of them were presented with knee pain and/or limitation of movement. Conclusion: High resolution ultrasound gives high accuracy specificity which nearly approaches that of MRI. As regarding its sensitivity, it is of lower comparable value than that of MRI. So it is preferable to use high resolution ultrasound as a preliminary investigation for diagnosis as the patient can avoid performing the high cost MRI unless the patient was proved to be injured and needing MRI.
