Knee joint
The knee joint is a crucial hinge joint that connects the thigh bone (femur) to the shin bone (tibia). It allows movement, enabling activities like walking, running, and jumping. The knee is surrounded by cartilage, which cushions and protects the bones, and is stabilized by ligaments that connect the bones and provide support. The joint also involves the kneecap (patella), which helps in movement and protects the joint. Common issues include injuries, arthritis, and cartilage damage, which can affect mobility and cause pain. Proper function of the knee is essential for everyday activities and physical fitness.
