Internal derangement of the knee refers to a medical condition characterized by disruption or damage to the internal structures of the knee joint, which can lead to various symptoms and functional impairments. It commonly affects the ligaments, menisci, cartilage, and other components within the knee.
This condition typically arises from traumatic injuries, such as sudden twists, falls, or direct blows to the knee, although chronic overuse can also contribute to its development. The internal structures of the knee joint, which are responsible for stability, shock absorption, and smooth movement, can be affected in several ways.
Ligamentous injuries, such as tears or sprains, are common forms of internal derangement, often involving the anterior cruciate ligament (ACL), medial collateral ligament (MCL), or posterior cruciate ligament (PCL). These injuries may cause pain, swelling, instability, or restrictions in movement.
Meniscal damage is another type of internal derangement, involving the C-shaped cartilage discs (menisci) within the joint. Meniscal tears often lead to localized pain, swelling, limited range of motion, clicking or locking sensations, and a feeling of instability in the knee.
In some cases, internal derangement of the knee can also involve damage to the articular cartilage, the smooth lining covering the ends of bones in the joint. This can potentially lead to chronic pain, stiffness, joint degeneration, and reduced overall joint function.
Diagnosis of internal derangement of the knee typically involves a comprehensive evaluation by a healthcare professional, including a thorough medical history, physical examination, and diagnostic imaging tests such as X-rays, MRI, or CT scans.
Treatment options for internal derangement of the knee depend on the specific structures affected and the severity of the injury. It may include conservative
