Question #5: What's Something You Cringe at Regarding Hip & Knee Health?

Interviewer: Knowing what you know about hips and knees, you cringe a little when you see someone doing what?

Dr. Peters: Marathon running.

Interviewer: Really? Expand on that a little bit.

Dr. Peters: Well, that's not really fair, because, you know, if you look at it, marathon runners are usually super-fit. They're slight people, and they're highly conditioned, and there's actually not a lot of evidence that says running well into your 50s and 60s leads to arthritis, but it gets to the point of overuse in very vigorous athletic activity, so for instance, NFL players tremendously high rate of hip and knee arthritis. So extremely high-impact, competitive athletics, I think, is very hard on your hip and knees

So I hear parents a lot of times asking me, "Well, should my kid play football?" "Should my kid not play basketball?" Well, no. We have to accept that there are some risks in the things that bring enjoyment in life, and recreation's one of those things.

Question #7: What About Supplements for Joint Health?

Interviewer: What do I need to know about nutritional supplements that say that they will help my joint health?

Dr. Peters: Save your money. In most cases, a once-a-day multivitamin is probably all that you need.
