The two Meniscus in your knee sit between the cartilage surfaces of the knee bones and distributes body weight across the joint. When you tear cartilage in your knee, you have injured your meniscus. Symptoms of a meniscus tear include knee pain, swelling, tenderness of the meniscus, popping or clicking in the knee, joint locking, and limited motion in the knee joint. You can treat a torn meniscus in several ways - use cold therapy (ice packs, ice wraps) to help bring down the swelling. Since a torn meniscus means that the cartiage in your knee cap is no longer available to act as a cushion, meniscus knee braces are perfect for helping stabilize the knee area. Please consult a doctor for diagnosis and further treatment of your meniscus injury.
