Abstract
Introduction: Trauma to the knee joint is a major source of morbidity in young active people. An accurate diagnosis concerning the injury is important for early operative as well as non-operative treatment. The most extensively utilised diagnostic techniques to assess knee joint damage are arthroscopy and MRI.
Objective: To detect various types of traumatic knee lesions using MRI and to compare the diagnostic accuracy of MRI with arthroscopy in the evaluations of ligamentous and meniscal injuries of the knee joint.
Methods: A prospective study was done at the department of orthopaedic. A total of 50 patients (50 knees) were investigated, with 42 males and 11 females ranging in age from 16 to 61 years and presenting with various knee joint injuries.
Results: Our comparison of these two methods in knee injuries comes to specific conclusions that are consistent with earlier research. Anterior and medial meniscal injuries are more common than posterior and lateral meniscal injuries. The description of the nature of ACL and PCL injuries by MRI assists the orthopaedic surgeon in deciding whether to proceed with conservative or final reconstruction by arthroscopy.
Conclusion: Meniscal and ligamentous injuries are common in people who have had knee trauma. When compared to PCL and LM, the ACL and MM are more usually torn. While ACL and medial collateral ligament tears are associated with MM tears, lateral collateral ligament injuries are strongly associated with LM tears.
