Introduction: Magnetic Resonance Imaging (MRI) as a non-invasive modality plays a vital role in assessment of a wide spectrum of internal knee derangements. This study focuses on the commonest anatomical derangement and reveals the importance of MRI to characterize the pattern of derangement in the assessment of the patient with knee injury. Methods: This is the hospital based prospective study conducted among 65 patients referred to department of radiology with first presentation of knee injury during two years period from August, 2013 to August, 2015. Patient fulfilling the inclusion criteria underwent Magnetic Resonance Imaging knee in SIEMENS MAGNETOM C 0.35 Tesla MRI machine, after taking written informed consent. Descriptive analysis of data was analyzed using SPSS 20.0 program Result: Of the total 65 patients with knee injury, Sport injuries were the most common mode of knee injury. 63 cases with trauma had findings on MRI. Most of the cases presented with joint effusion (59 cases). Anterior Cruciate Ligament (ACL) tear is the commonest injury (37 cases) during knee trauma followed by Medial Collateral Ligament (MCL), Medial Meniscus, Posterior Cruciate Ligament (PCL), Lateral Meniscus and Lateral Collateral Ligament(LCL) injuries. Conclusion: MRI as a high-contrast soft-tissue imaging technique can be used as a noninvasive modality to assess a wide spectrum of internal knee derangements in a patient with knee injury. Specific pattern of bone bruise can guide us to narrow our diagnosis.

Background The elbow is one of the most commonly dislocated joints, and dislocation is usually accompanied with an assortment of soft tissue injuries. The purpose of this study was to retrospectively analyze and describe the patterns of ligamentous, tendinous, and muscular injuries in patients with an acute elbow dislocation and subsequent magnetic resonance image (MRI) evaluation. Methods From 2008 to 2020, 235 patients clinically diagnosed with an elbow dislocation were seen in the department, of which only 19 underwent an MRI of the affected elbow. Twelve patients met inclusion criteria, and MRIs were evaluated by both a radiologist and an upper extremity orthopedic surgeon. Magnetic resonance images were assessed for injury to the ulnar collateral ligament (UCL); radial collateral ligament (RCL); lateral ulnar collateral ligament (LUCL); common flexor and extensor tendons; biceps, brachialis, and triceps tendons; fracture; and joint effusion. Results Magnetic resonance imaging findings included the following: UCL was injured in 11 of 12 patients; RCL was injured in 9 of 12 patients; LUCL was injured in 9 of 12 patients; common flexor tendon was injured in 11 of 12 patients; and common extensor tendon was injured in 9 of 12 elbows. The biceps, brachialis, and triceps tendons showed injury in 1 of 12, 2 of 12, and 2 of 12 elbows, respectively. Four elbows had at least 1 fracture present, whereas 8 demonstrated an effusion. Conclusions In this series, injuries to the UCL and common flexor tendon were most common. Although ligamentous injuries are exceedingly common in elbow dislocations, large studies of MRI findings prove difficult due to MRI costs.

Background: The purpose of this study was to determine whether magnetic resonance imaging findings are accurate and can be confirmed surgically. Methods: Surgical correlation of preoperative magnetic resonance imaging findings of trauma to tendons and ligaments of the foot and ankle were retrospectively studied in 28 patients who had undergone surgical repair for tears of the Achilles tendon, posterior tibial tendon, peroneal tendons, collateral ligaments, and other pathology. Results: This study corroborates that magnetic resonance imaging findings are confirmed surgically 83% of the time for tears of tendons and ligaments of the foot and ankle. Larger tendons (Achilles, posterior tibial tendon) have a 94% sensitivity and 6% specificity, respectively. Collateral ligament and high ankle sprains have a 73% sensitivity. There is a lower sensitivity of 57% for peroneus brevis and longus ruptures. Conclusion: This study revealed that peroneal trauma can be an isolated event and in some cases can occur with other traumatic pathology such as collateral ligament tears.
