Supposedly every pound you weigh puts four pounds of pressure on your joints. So if you're supposed to weigh 175 but actually weigh 225 you are putting 900 lbs vs 700 lbs of stress onto your joints. But how would you explain 310-pound NFL linemen who much more overweight than that?

And these guys are RUNNING, not walking like most adults.

A 310 pound lineman has the advantage of being an athlete who has developed strong muscles. A portion of his weight is attributed to his built up muscles. He can run more easily than a 310 pound construction worker, who may have strong upper body strength due to the nature of his work. However, running is not a part of a construction worker's job as it is for an NFL lineman. For most people, being overweight can put an enormous amount of pressure on the knees which can cause pain. Many football players do experience knee pain, not due to their weight but to the unnatural twisting and turning during a game and injuries.

Weight is mostly irrelevant with regard to knee pain. Knee pain (well knee pain not caused directly by injury) is caused by various types of chronic degeneration of the joint....mostly osteoarthritis. This is a metabolic problem, close related to osteoporosis (same disease, different cells involved). You are not more likely to develop this if you are heavy than if you are thin, although, if you have it, the extra weight might make the disease more debilitating, early on and might cause problems after a knee replacement.

Particularly in women, bodyfat actually has somewhat of a protective effect against both osteoporosis and osteoarthritis. Fat is one of the tissues that creates estrogen. As a woman ages, the sex organs reduce production of estrogen but the fat does not.

Look. It's real simple. Do fat people have more knee pain than everyone else. Do they have greater incidents of degenerative arthritis leading to knee and hip replacement or other degenerative problems like low back pain?

The answer to that question is no.....as measured again and again in cross sectional research on the matter. That's the difference between theory and research. The two mostly don't line up, which is why you do research....to cull out the 5% of theory that pans out with useful stuff.

If you have knee pain, losing weight can help. However, it won't fix the problem. Neither will it reduce you risk. In other words. If you have knee pain due to degenerative arthritis, losing weight can help reduce your pain. Reducing pain can delay the need for knee replacement if the degeneration is that bad. What it won't do, is slow the progress of the disease.

We are all built differently. There is no doubt that 99.999% of us could never hold up to the abuse that NFL players put on their bodies. They have not only trained most of their lives to do what they do, but they were genetically gifted to begin with. Some people can handle more weight ( I don't have any joint pain/problems at 275, for instance) whereas others who are quite light do still suffer.

Insofar as the answer being simple, or perhaps incomplete, that is a question to ask your doctor. It would be a bit presumptuous to think I could give you any kind of diagnosis based on this. S/He is the only one who can provide you with real answers, but you need to ask them.

There are a million things that can cause pain, and I am sure that you are going to hear quite a few of them from other answerers. Remember that diagnosis are best left to the doctors. There are only a few symptoms but so many ailments.

Good luck!

every 5 pounds of weights equals an additional 400 pounds per square inch. so yeay being 40-50 pounds overweight will destroy the knee caps without fail.

Of course its too simple to blame only weight. There are many reasons for knee pain. But extra weight will only add to the problem. Lose weight first...then see how the knee is.
