M23.262
Derangement of other lateral meniscus due to old tear or injury, left knee
Clinical Classification Guidelines
Medical Intelligence & Overview
The ICD-10 code M23.262 refers to a condition where the lateral meniscus in the left knee is deranged as a result of an old tear or injury. The menisci are two crescent-shaped cartilage structures that cushion and stabilize the knee joint. A derangement indicates a displacement or abnormal positioning of the meniscus, often causing discomfort and affecting knee function. This condition is generally linked to previous trauma that has led to damage in the meniscus tissue, which may not have healed properly or have re-injured over time.
Causes & Symptoms
Clinical Causes: Previous trauma or injury to the knee, such as sports injuries or accidents Degenerative changes in the meniscus due to aging Repeated stress or overuse of the knee joint Previous surgical procedures involving the knee Sudden twisting or pivoting movements that strained the knee Chronic instability or ligament injuries contributing to meniscal damage
Key Symptoms: Knee pain, especially on the outer side of the knee Swelling around the knee joint Limited range of motion or stiffness A sensation of the knee locking or catching during movement Weakness or giving way of the knee Discomfort worsened by activities involving bending or twisting
Diagnostic & Treatment
Diagnosis Path: Diagnosing a lateral meniscus derangement typically involves a clinical examination where a healthcare professional assesses knee stability and looks for signs of swelling or tenderness. Imaging tests play a crucial role; magnetic resonance imaging (MRI) is especially useful for visualizing meniscus injuries and confirming a derangement. In some cases, arthroscopy—a minimally invasive surgical procedure—may be performed to directly view the meniscus and determine the extent of damage.
Treatment Protocols: Treatment options focus on relieving symptoms, restoring knee function, and preventing further damage. They may include:
