Polvinivel
Polvinivel refers to the knee joint in Swedish. It is a complex hinge joint connecting the femur (thigh bone) and the tibia (shin bone), with the patella (kneecap) also playing a crucial role. This joint allows for flexion and extension of the leg, essential for locomotion such as walking, running, and jumping. It is stabilized by a network of ligaments, including the anterior and posterior cruciate ligaments, and the medial and lateral collateral ligaments, which prevent excessive movement and maintain stability. The menisci, cartilage structures within the joint, act as shock absorbers and help distribute weight. Injuries to the polvinivel are common and can range from ligament tears and meniscal damage to osteoarthritis, a degenerative condition. Rehabilitation often involves physiotherapy to restore strength, flexibility, and function. Medical interventions can include medication, injections, or surgery depending on the severity of the condition. Understanding the anatomy and biomechanics of the polvinivel is crucial for diagnosing and treating knee-related ailments.
