The objective of this study was to evaluate multiple morphological features on MR images 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 May 2017 and April 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 transepicondylar 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 have 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 femur’s lateral condyle. MTS is more than LTS in both ACL insufficiency patients and ACL intact patients.
