Knäområden

Knäområden refers to the regions surrounding the knee joint. This anatomical area is crucial for locomotion and includes several key structures. The knee joint itself is a complex hinge joint formed by the articulation of the femur (thigh bone) and the tibia (shin bone). The patella, or kneecap, is a sesamoid bone that articulates with the femur, contributing to knee extension.

Surrounding the bones are various soft tissues. Ligaments provide stability to the joint, with the anterior and posterior cruciate ligaments located within the joint and the medial and lateral collateral ligaments on the sides. Cartilage, specifically articular cartilage, covers the bone surfaces, allowing for smooth movement and shock absorption. The menisci, C-shaped pieces of fibrocartilage, further enhance stability and load distribution. Muscles such as the quadriceps femoris and hamstrings play vital roles in flexing and extending the knee. Tendons connect these muscles to the bones, transmitting force.

Injuries to the knäområden are common and can affect any of these structures, leading to pain, swelling, and limited mobility. Common conditions include sprains, tears of ligaments or menisci, and osteoarthritis. The health and function of the knäområden are essential for daily activities.
