Abstract

Background: The knee joint can be imaged using a variety of modalities of which MRI is the most recognized technique posing an excellent imaging modality for all the components of the knee joint namely cartilage, ligaments, tendons, menisci, muscles, bone and bone marrow. Injuries to the intra articular structures can be diagnosed with a high degree of sensitivity and specificity. Subjects and Methods: Patients with history of pain in the knee with or without swelling where MRI was used as a modality in diagnosing the cause. All patients will be subjected to MR imaging and followed by Arthroscopy. Results: Out of the 40 ACLs diagnosed as completely ruptured at MRI, 27 were confirmed to be completely ruptured, 13 were concluded to be partially ruptured and 6 were found to be normal on arthroscopy. An ACL rupture diagnosed on MRI is an important indicator to look for the co – existence of other injuries of that knee joint. Of all the patients accounting for ACL injury ACLs that were classified at MRI as normal were seen to be normal even on arthroscopy. There by giving MRI a negative predictive value of 97.1 percent for ACL injury. Conclusion: MRI increases diagnostic confidence and potentially reduces the need for diagnostic arthroscopy.
