KNEE JOINTThe knee joint is the biggest and most complicated joint in the human body, it is composed of two big bones - thigh bone, tibial bone and patella. The surface on which these two large bones meet is filled with two crescent-shaped cartilagous shapes - meniscus. Stability of the knee joint is further secured by ligaments, anterior and posterior cruciate ligaments, and collateral ligaments, big role is also played by tendon - attachment of the thigh muscle, which is attaching the patella to the front side of the joint. Integral parts of the knee are tendons and attachments of the surrounding muscles, which thanks to their tension create another stable support.
Movement in the knee joint is a complicated combination of rolling movement, rotation and shifting. Burden on the joint during walking is multiple times the weight of the body, and it only increases when walking on the stairs, up the hill and when carrying heavy objects. Two of the longest human bones are meeting in the knee, the joint then basically works as a lever, which means that the knee joint has to handle big force.
