gewrichtsdruk

Gewrichtsdruk, often translated as joint pressure, refers to the forces experienced within a joint. These forces arise from a combination of factors including the weight of the body, muscle contractions, and external loads. When you stand or walk, gravity exerts a downward force that is transmitted through your skeletal structure and distributed across the articular surfaces of your joints. Muscle activity around a joint also generates forces that can compress or pull on the joint structures. External forces, such as lifting a heavy object or impact from activities like running, can significantly increase these internal joint pressures.

The cartilage lining the ends of bones within a joint plays a crucial role in managing these pressures. This smooth, resilient tissue acts as a shock absorber and allows for low-friction movement by reducing direct bone-on-bone contact. The synovial fluid within the joint capsule further lubricates the surfaces, enabling them to glide easily under pressure. Maintaining healthy joint pressure is essential for joint function and longevity. Excessive or prolonged high joint pressure, particularly without adequate cartilage and fluid support, can contribute to wear and tear, potentially leading to conditions like osteoarthritis. Conversely, insufficient pressure, such as during prolonged immobility, can also negatively impact joint health by reducing nutrient supply to the cartilage.
