Why are knees so weak

Not only is the knee structurally less stable than the hip, it’s also far more restricted. As a hinge joint, the knee can move forwards and backwards with a very limited amount of twisting.

Your knees absorb a huge amount of pressure with every step — typically one-and-a-half times your body weight. That pressure, plus regular wear and tear, takes a toll over time.
