Pak J Med Health Sci Jan ;7(1):227-30.

Aim: To determine the diagnostic accuracy of 1.5 tesla MRI in the diagnosis of meniscal tears of knee joint taking arthroscopic findings as gold standard. Place and duration of study: From July 2011 to December 2011, at Sheikh Zayed Post graduate medical Institute, Lahore (Radiology and Orthopedic departments). Subjects and methods: 50 patients fulfilling the selection criteria were identified, referred from outpatient department of orthopedics to Radiology department Sheikh Zayed hospital were included in the study. Their informed consent and demographic profile was obtained. 1.5-Tesla MRI was done by single technician of MRI department. Arthroscopy was done by professor of orthopedics to confirm the findings of MRI. All this information was recorded on proforma and results were evaluated. Results: A total of 50 patients were included in the study. 48(96%) were male and 2(4%) were female. The age ranged from 15–55 years. Mean age of patients was 30.4 ±5.91 years. Our study revealed high sensitivity (97%), high specificity (94%) and accuracy (96%) for the meniscal injuries of knee joint in comparison to arthroscopy. Conclusion: Magnetic resonance imaging is a good, accurate and non invasive modality for the assessment of meniscal injuries.
