LIGAMENT AND MENISCAL INJURIES FOLLOWING KNEE TRAUMA- ROLE OF THE MRI AND ITS CORRELATION WITH ARTHROSCOPY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 81
Abstract
BACKGROUND MRI is an excellent imaging modality for assessing internal derangement of the knee. Its non-invasive nature, excellent soft tissue contrast and no radiation risk makes MRI a boon in knee imaging. The aims of the study are1. To know the occurrence of meniscal and ligament injuries following knee injury. 2. To evaluate diagnostic performance of MRI following knee injury in correlation with arthroscopy. MATERIALS AND METHODS This is a prospective study including 70 patients conducted at our institution over a period of 3 years from October 2006 to October 2009. Only the patients with history of knee trauma were included in our study. All the patients initially underwent MRI and subsequent arthroscopy. The pattern of injury was recorded. The location, type and grades of meniscal and ligament tears were recorded by experienced radiologist. Later MRI findings were correlated with arthroscopy findings. RESULTS On evaluation of MRI findings of 70 patients including 60 (85.7%) male and 10 (14.28%) female patients, the most commonly detected injuries were of anterior cruciate ligament. The sensitivity, specificity and accuracy of MRI for detecting medial meniscal injury were 92.3%, 90.9% and 91.4% respectively. Lateral meniscus (88.0%, 88.9% and 88.6% respectively). Anterior cruciate ligament (91.8%, 95.2% and 92.9% respectively) and posterior cruciate ligament (100%, 98.5% and 98.6% respectively). Comparisons between qualitative variables were done using the chi-square test. CONCLUSION MRI is highly sensitive and accurate at identification of cruciate ligament and meniscal tears. A close agreement was obtained between MRI and arthroscopic diagnosis. In case of meniscal tears, full description of meniscal tear (location, grade and configuration) had important implications on treatment of these patients.
