The Effect of the Cause of Trauma, Sports Activity As Well As Body Mass on Lesions of the Knee Joint Evaluated Using Magnetic Resonance

Abstract

Introduction: The most common cause is stated to be a fall, bend as well as spontaneous pain. The changes which lead to pain in the knee may be detected with a non-invasive method such as magnetic resonance. The aim of this study is to see whether a linkage exists between the pain intensity and the degree of the lesion on any structure of the knee. Whether body mass plays a significant role in relation to the manner in which the injury occurred. Material and Methods: Our study included 261 patients which met our inclusion criteria for participation in this study. All patients signed an informant consent for participation in the study. The study will involve a prospective analysis with Magnetic Resonance Imaging of the knee for a period of 1 year using an MRI of 1.5 T. The data is acquired using a questionnaire regarding the injury filled by the patient. In our study 261 knee MRIs were processed and analysed in patients with acute injury to the knee, with a negative radiograph of the knee and persistent pain not longer than 1 month despite undergoing a conservative treatment. We analyze in the study the relationship between demographic characteristics of patients with trauma to the knee and the manner in which the injury occurred. Results: With regard to the gender distribution: 65.13% were male The manner of injury in the greater part of the subjects was bending (40.23%).In terms of localization of the pain, the majority of subjects reported that they felt the pain in the medial part of the knee (47.13%).When analysing MRIs of the knees, the majority showed a lesion on the cartilage of the medial condyle on the femur in 88 (33.72%) subjects.In our study the MRI findings showed a lesion on the posterior horn on the medial meniscus in 175 (67.05%) subjects.With an MRI findings of a lesion on the ACL were present in around 40% of the subjects.Patients with lesions on the ACL had a significantly more frequent occurrence of bone oedema (p=0.043).All patients with a combined trauma to the anterior cruciate ligament and the posterior horn of the medial meniscus also had a bone oedema Type 1 and Type 2. Conclusion: Age and body weight do not have an impact on the manner in which the trauma occurs and the type and grade of the lesions of the knee.Males are more prone to sports traumas. The intensity of pain does not depend on the cause of injury.All patients with a combined trauma to the anterior cruciate ligament and the posterior horn of the medial meniscus had a bone oedema Type 1 and Type 2. Bone oedemas should always be searched during an MRI analysis of the knee as it can lead to finding the lesion.
