A Closer Look At The Knee
The Knee is the largest joint in the body and is central to nearly every routine activity. The knee joint is formed by 3 bones: the lower end of the thigh bone (femur), the upper end of the shin bone (tibia), and knee cap (patella). Thick, tough tissue brands called ligaments connect the bones and stabilize the joint. A smooth, shiny, plastic-like lining called cartilage covers the ends of the bones and prevents them from rubbing against each other, allowing for flexible and frictionless movement. Cartilage also serves as a shock absorber, cushioning the bones, from the forces between them. A soft tissue called synovium lines the joint and produces a lubricating fluid that reduces friction and wear.
