Meniscus injuries are the fourth most common injury in runners according to a study of over 2000 runners seeking medical care.
The meniscus is a crescent shaped structure that provides cushioning and stability in the knee joint.A tear in this cartilage may occur from twisting in a squatted position. Symptoms include a locking or catching sensation in the knee as well as swelling. The average age of runners with a menicsus injury is 43 years old and males are twice as likely to experience a tear. Degenerative meniscal tears are more common in older runners and may or may not cause any symptoms.
