Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 2
Abstract
Background: The knee joint is a common site of injury due to trauma, repetitive activities, and sports activities.Clinical diagnosis, encompassing an accurate history, thorough examination and interpretation of investigations, is an art all doctors are expected to master during their career. A number of previous studies have examined the accuracy of clinical diagnosis in traumatic meniscal or ligamentous injuries of the knee. Multiple imaging modalities are currently used to evaluate pathologic conditions of the knee. Magnetic resonance imaging has a better soft tissue contrast and multi planar slice capability which has revolutionized and has become the ideal modality for imaging complex anatomy of the knee joint.Arthroscopy considered to be the ‘gold standard’ investigative method. Which can be used in its dual mode, either as diagnostic and/or as therapeutic tool.Aim of the study was to correlate clinical, radiological and arthroscopic findings of meniscal and anterior cruciate ligament injuries of knee. Materials and methods:This is a prospective study involving 30 patients with history of knee injuries who have admitted in Department of Orthopedics, Narayana medical college was conducted for a period of two year and were scheduled to undergo arthroscopic surgery of the knee for either meniscal or ACL injury based on clinical and Magnetic Resonance Imaging (MRI) findings were included in the study. Results:30 patients were studied comparing clinical examination, MRI with arthroscopy and were analyzed. Clinical examination showed sensitivity, specificity, Positive Predictive value (PPV), Negative Predictive value (NPV), accuracy of 68.1%,62.5%,83.3%,41.6%,66.6%respectively for medial meniscustear,75%,83.3%,75.0%,83.3%,80% respectively for lateral meniscus tear and 91.3%,85.7%,95.4%,75.0%,90.0%, respectively for Anterior Cruciate Ligament (ACL) tear. MRI findings showed sensitivity, specificity PPV, NPV, accuracy of 68.1%, 75.0%, 88.2%,46.1%,70.0% respectively for medial meniscus, 50.0%,83.3%,66.6%,71.4%,70.0% respectively for lateral meniscus tear, 78.2%,85.7%,94.7%,54.5%,and 80.0% respectively for ACL tear. Conclusion: Clinical tests to detect ACL and lateral meniscus injuries have a high degree of correlation when compared to arthroscopy and MRI. Clinical tests to detect medial meniscus injuries have a lower degree of correlation compared to MRI and arthroscopy.
