Abstract
The aim of present study is to determine diagnostic accuracy of MRI in diagnosis of various ligamentous and meniscal injuries. The patients were briefed about procedure. The noise due to gradient coils and the need to restrict body movements during the scan time was explained to the patient. Patient is placed in supine position with the knee in a closely coupled extremity coil. The knee is externally rotated 15-20Ëš (to facilitate visualization of the ACL completely on sagittal images and is also flexed 5-10Ëš. Result: In our study medial meniscal tears (72%) were more common than lateral meniscal tears. Most of the medial meniscal tears were located in the posterior horn constituting 42.8% of cases. Conclusion: Most of the patients were males. Involvement of the left knee was more common than right knee. Commonest lesion detected in our study was meniscal tears. Medial meniscal tears were more common than lateral meniscal tears. Most of the meniscal tears were of grade 3 and were located in posterior horn. Complex tear was the most common morphological type of tear in medial meniscus and in lateral meniscus vertical type was the most common type. MRI should be done in every patient of suspected internal derangement of knee joint, to save a patient from unnecessary arthroscopy
