Anthropometric Study of Knee Joint in Anterior Cruciate Ligament Insufficient Knees using Magnetic Resonance Imaging

PURPOSE: The objective of this study was to evaluate morphological features on MRI in patients with ACL insufficient knees. METHODS: Magnetic resonance imaging (MRI) of the knee of 40 anterior cruciate ligament insufficient patients and 20 anterior cruciate ligament intact patients who came to Katuri Medical College and Hospital, Guntur, between Sep 2017 and August 2018 were reviewed. Their intercondylar notch, femoral condyles dimensions and tibial slopes were measured using MRI. RESULTS. The ACL insufficient knees and ACL intact knees were comparable in terms of intercondylar notch width. Lateral femoral condyle height and trans epicondylar axis are more in ACL insufficient knees. Medial posterior tibial slope is more than Lateral posterior tibial slope in both ACL insufficient knees and ACL intact knees. CONCLUSION: The ACL insufficient patients had more Lateral femoral condyle width, intercondylar notch width, intercondylar notch height compared to ACL intact knees. ACL-ruptured patients had statistically significant smaller heights of femurs lateral condyle. MTS is more than LTS in both ACL insufficiency patients and ACL intact patients.
