A meniscal tear is an injury of the shock-absorbing cartilage in the knee. The meniscus is a C-shaped fibrous cartilage that is found in certain joints forming a buffer between the bones. The meniscus also serves as a shock-absorption system, assists in lubricating the joint, and limits the joint flexion and extension.
