In between the bones that meet to form the knee joint are two wedge-shaped pieces of cartilage that act as a cushion and "shock absorber" for the joint. These pieces of cartilage are the medial meniscus and lateral meniscus. One of the most common sources of knee pain is due to a rip or tear in the meniscus. Athletes frequently injure menisci due to the bending, twisting, and sudden movements required by sports. BioSkin Knee braces are designed to alleviate pain with medical-grade compression and provide pressure-relieving support that allows the menisci to heal.
