Abstract
Background: Knee injuries are common, especially when taking part in sport. Injuries to soft tissues, such as ligaments, cartilage (meniscus) and tendons, are the most common, though damage to the bones is also possible [1].
Aim of the work (objectives): The purpose of the study was to evaluate the role of high resolution ultrasound (HRUS) in comparison to MRI in diagnosis of meniscal and cruciate ligaments injury of the knee.
Subjects and methods: In a period from January 2017 to September 2017 a total of 78 persons were examined. They were 62 males & 16 females, with an age range between 10-70 years, they were classified to control group and 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 45 symptomatic patients with history of acute or chronic knee trauma, 36 males and 9 females. Their ages ranged from 15- 69 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.
Discussion: The use of ultrasound for evaluation of the knee joint lesions is increasing. Although, it cannot replace magnetic resonance imaging.
Conclusions: 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.
Key Words: (HRUS) High resolution ultrasound, (MRI) Magnetic resonance imaging, (ACL) Anterior cruciate ligament, (PCL) Posterior cruciate ligament.
