Study of the Internal Derangement of the Knee using Ultrasound and MRI

Abstract

Musculoskeletal sonography is rapidly evolving modality which is gaining popularity for the evaluation and management of joint and soft tissue disorder the purpose of this exhibit was to study the internal derangement of the knee using ultrasound and MRI. All patients (50 patients) were scanned by MRI 1.5 Tesla as standard and by ultrasound using high linear frequency transducer. The study took place in Sudan Khartoum 2014-2015. The part examined in the knee include meniscuses (Lateral anterior, lateral posterior, medial anterior and medial posterior meniscus), ligaments (anterior curciate, posterior curciate, medial collateral and lateral collateral ligament), supra patella, infra patella, posterior component and presence or absence of backer cyst. The results showed that the overall accuracy of ultrasound in diagnosing the meniscuses was 95.5%, for collateral ligaments was 99.7%, for supra and infra patellar was 50%., and for posterior component was 61%; With a sensitivity of 91.7 for diagnosing backer cyst.
