S83.2

Clinical Causes: Sudden twisting or rotation of the knee, especially when bearing weight Direct blow or trauma to the knee during sports or accidents Degenerative changes in the meniscus due to aging or wear and tear Overuse of the knee, such as frequent kneeling or repetitive motions Sudden changes in activity level or movement mechanics

Key Symptoms: Pain, especially along the joint line of the knee Swelling and stiffness within the knee Limited range of motion A sensation of the knee locking or catching during movement Feeling of instability or the knee giving way Tenderness when touching the affected area

Diagnosis Path: Diagnosing a meniscus tear typically involves a physical examination where a healthcare provider checks for swelling, tenderness, and signs of a mechanical problem such as locking or catching of the knee. Special tests, like the McMurray test or Apley test, may be performed. Imaging studies such as MRI scans are frequently used to confirm the extent and location of the tear, providing detailed images of the soft tissues within the knee.

Treatment Protocols: Treatment approaches depend on the severity and type of meniscus tear, as well as the patient's activity level and overall health. Options include: - Rest and activity modification to reduce stress on the knee - Ice application to decrease swelling and relieve pain - Non-steroidal anti-inflammatory drugs (NSAIDs) for pain relief - Physical therapy programs aimed at strengthening the muscles around the knee and restoring stability - Arthroscopic surgery to repair or remove the damaged meniscus tissue, particularly in active individuals or severe cases Most tears can be managed effectively with a combination of conservative treatment and, when necessary, surgical intervention, leading to good functional recovery.
