Learning objectives - to explore the MRI features, clinical significance, and treatment options for various knee conditions, including osteochondral lesions, meniscal tears, ligament injuries, and bone disorders, with a focus on the specific MRI sequences used for diagnosis
Read more Background This analysis highlights how advanced MRI techniques enhance diagnostic accuracy and contribute to more effective treatment decisions for patients with knee pathology.The standard protocol should include both T2-weighted images, which are sensitive to fluid, and T1-weighted images.Proton density (PD) and T2-weighted (T2W) sequences are frequently preferred for assessing fibrocartilage, while fat-saturated PD sequences are ideal for evaluating hyaline cartilage. T1-weighted (T1W) and fat-saturated T2W sequences are used for evaluating bone marrow.Each joint should be imaged in all three planes. A...
Read more Findings and procedure details A) OSTEOCHONDRAL LESIONSThe mature osteochondral unit includes smooth joint cartilage, the bone plate beneath it, and the spongy bone underneath [1]. Healthy articular cartilage contains a small number of chondrocytes (1%-5% by volume), and the majority of the tissue is composed of an extracellular matrix that contains water (65%-85%), collagen (10%-20% by wet weight), and proteoglycans (5%-10% by wet weight) [1]. Articular cartilage has four zones: the superficial (tangential) zone, middle (transitional) zone, deep (radial) zone, and the calcified zone...
Read more Conclusion In summary, MRI plays a crucial role in evaluating knee pain by providing a detailed assessment of ligaments, menisci, bones, and surrounding soft tissues. While radiographs complement MRI, especially in identifying subtle bony injuries, collaboration between orthopedic surgeons and musculoskeletal radiologists is essential for an accurate diagnosis and treatment. This partnership enhances the understanding of knee anatomy and injury mechanisms, leading to improved patient care, faster intervention, and better overall outcomes.
