A meniscus tear is an injury to the cartilage in the knee, specifically the meniscus, which acts as a cushion between the thigh bone and the shin bone. This type of injury often occurs during activities that involve twisting or turning, especially when the knee is bent. Symptoms may include pain, swelling, and difficulty moving the knee. Treatment for a meniscus tear can vary depending on the severity of the injury. Minor tears may heal with rest, ice, and physical therapy, while more severe cases might require surgery to repair the damaged cartilage. Early diagnosis and appropriate care are essential for recovery.
