Each pound of weight lost reduces knee pressure by four pounds during walking, six pounds during stair climbing, and eight pounds during running.

“every pound of weight loss up top is four pounds of weight loss through the knee was just walking and it becomes amplified is that that's just again the mechanics mechanics of the knee so your center of gravity and and and how that applies torque into the knee is part of the reason why that body weight is amplified so it's not just pound for pound so when patients gain the pound they're putting four more pounds of pressure their knee was just walking six pounds more with going up and down the stairs eight pounds more with running”
