Stepping Down Pain Free

Knee pain while descending stairs is often due to the force on your kneecap (patella), which studies show is 3.5 X your body weight. If you weigh 140lbs, the force on your patella can be as much as 490lbs! That is a lot of stress on your knee, and the pain will be magnified if you have weak muscles or degeneration of the cartilage in the joint.
