Purpose: 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.Keywords: Magnetic resonance imaging, anthropometric study, knee joint, anterior cruciate ligament IntroductionThe dimensions of the intercondylar notch are such that there is little space not filled by the cruciate ligaments. It is this intimate relationship between the cruciate ligaments and the notch that may give rise to impingement of these structures following anterior cruciate ligament (ACL) reconstruction. Impingement of the ACL on the inter condylar notch will occur if the notch is steno tic, the ACL is relatively large, or a combination of both. This impingement will jeopardize the surgical repair. Magnetic resonance imaging (MRI) has been proven as the gold standard method of choice for non-invasive evaluation of the ACL. Multiple studies have been executed in which measurements were taken on MR images to identify the characteristics of the ACL and its surroundings [1, 2] . Furthermore, MRI has been utilized during the evaluation of knee kinematics with and without an ACL rupture [3,4] . To the best of the authors' knowledge, an assessment of multiple morphological features and their risk for ACL rupture has not been performed. Some studies have investigated the morphological features on the femoral side, while others have studied those on the tibial side. As such, the objective of this study was to evaluate multiple morphological features on both the femoral and tibial sides of the knee on MR imaging in patients with and without ACL rupture. In this way, it is possible to analyze the tibial and femoral morphological features both separately and combined and to evaluate a possible morphological relationship. The hypothesis of this study was that multiple individual and combined morphological features that confer a higher risk of sustaining an ACL rupture could be identified. This complete assessment of multiple morphological features and the...
To report the functional outcome in Posterior Cruciate Ligament (PCL) tibial avulsion fractures treated with open reduction and internal fixation with cancellous screw fixation through the posteromedial approach. Materials and Methods: This is a prospective and retrospective study conducted in Katuri medical college and hospital, Guntur, from September 2016 to May 2019. Total eight number of patients who came with White's type 2 & 3 displaced Posterior Cruciate Ligament (PCL) tibial avulsion fractures treated by open fixation with cancellous screws through the posteromedial approach.The pre-operative assessment was done with a magnetic resonance imaging for all the patients to confirm the fracture. Results: Post-operative radiographs were taken, which showed all avulsed fragments are well reduced and maintained. In all the cases, healing was evident by the end of 3 months. There are no symptoms of instability found clinically. The average Lysholm knee score was 94.3 (84-97). Conclusion:This study demonstrated treatment of White's type 2 & 3 displaced avulsion fracture of the posterior cruciate ligament by open reduction through the posteromedial approach and internal fixation using partially threaded screws gives very good functional and radiological results.
