What are common symptoms of a torn meniscus?

A torn meniscus often presents with specific symptoms that relate to the function and anatomy of the knee joint. Locking, clicking, and pain in the knee are classic symptoms of a meniscal tear. When the meniscus is torn, the fragments can move within the joint, leading to mechanical symptoms such as locking or catching during movement. Additionally, this damage can cause localized pain, particularly when the knee is twisted or under stress.

These symptoms are indicative of the meniscus being involved in the knee joint mechanics, which can lead to instability and discomfort. The locking sensation is particularly notable when a piece of the torn meniscus gets caught in the joint as it is moved, which is a hallmark sign of this injury.

Other symptoms, while they may occur in various knee injuries, do not specifically point to a meniscal tear. For example, swelling may occur but is not unique to meniscus injuries; numbness in the lower leg is more commonly associated with nerve issues rather than a meniscus problem; and limited range of motion in the hip relates to hip joint problems, not knee injuries. Thus, the presence of locking, clicking, and knee pain is a strong indicator of a torn meniscus.
