Because of its special design, featuring a thick rim and a thinner center, the device stays in place – even when squatting – without being attached to bones or any other surrounding tissue. Surgery is a very effective way to repair a torn meniscus. The meniscus is a c-shaped pad of cartilage (see diagram) that acts as the shock absorber of the knee and lower stress on the bones and cartilage.
