The healthy hip and knee joint


    • Cartilage provides a smooth surface for bones to slide during movement, absorbing shock and spreading loads evenly.
    • It lacks pain sensors, so injuries to cartilage may not directly cause pain.
    • Cartilage doesn’t have blood vessels; instead, nutrients are delivered via synovial fluid.
    • It functions akin to a wet sponge: under pressure, fluids are pressed out, and when relieved, they’re drawn back in.
    • When walking or applying loads to joints, cartilage absorbs shock and releases fluids into the surrounding capsule.
    • Removal of loads prompts cartilage to reabsorb fluids, maintaining its health.
    • In a healthy joint, there’s a balance between cartilage cell degeneration and regeneration.
