Anatomy of the knee

Anatomía rodillaAnatomía rodilla

The knee joint is formed by the distal femur, proximal tibia and the patella. There are ligament structures that provide stability to the bones: collateral ligaments and cruciate ligaments.

The entire surface of the knee is covered with a smooth structure called articular cartilage which allows a smooth gliding motion. Inside the knee joint there are two semicircular rings of cartilage called "menisci" that act as cushions. The synovial fluid is the lubricate that reduces joint friction.
