Diz eklemi, or the knee joint, is a crucial joint in the human body that connects the thigh bone (femur) to the shin bone (tibia). It allows for movement such as bending and straightening the leg, playing a vital role in activities like walking, running, and jumping. The knee joint is supported by ligaments, tendons, and cartilage, which help stabilize and cushion the joint. The knee joint is classified as a hinge joint, meaning it primarily allows movement in one direction. It is also one of the largest joints in the body, making it susceptible to injuries and conditions such as arthritis. Proper care and strengthening exercises can help maintain its function and health.
