The knee is a complex joint that is exposed to high loads and susceptible to tissue wear from excess loads or weakness as damaged cartilage in the knee heals poorly. The knee consists of cartilage surfaces that glide against each other, menisci that act as mobile gaskets, and bones, ligaments, and muscles that provide support and attachments.
