MRI ASSESSMENT OF CLINICALLY SUSPECTED MENISCAL TEARS
Background: Magnetic resonance imaging (MRI) is the tool commonly used in the diagnosis of meniscal tears. It has been suggested that, for clinically suspected meniscal tears, the adoption of routine MRI before therapeutic arthroscopy will reduce the number and cost of unnecessary invasive procedures.
The aim of this study was to document MRI yield in knee injuries clinically suspected as possible meniscal tears in Duhok city
Subject and Methods: This cross sectional study was conducted during the period from June to December 2014. A consecutive sampling procedure was used to enroll eighty cases of Knee injuries presenting with clinical features of meniscal tears. All patients underwent MRI examination by 1.5 Tesla machine.
Results: The mean age of the patients was 33.5 years. The number of males was 58 (72.5%) with mean age 29.55 years while females constituted 22 (27.5%) with mean age 44years.The results revealed that 64 patients (80%) were affected by tear in the medial meniscus compared to 16 patients (20%) in the lateral meniscus .
Isolated anterior horn tear was significantly more common in the lateral meniscus
(12.5%) than in the medial meniscus (1.25%) while isolated posterior horn tear was more common in the medial meniscus (66.25%) than the lateral meniscus (7.5%)
Conclusions: Meniscal tears were more common in males (~ 3/4th of cases) who presented at a younger age. Medial meniscal tears were four times as common as those affecting the lateral meniscus.
