Bone fractures around the knee fall into two groups: Those that lead to arthritis and those that heal just fine. Here is a brief guide to which is which.

We have all become hypersensitized to the effects of the things around us, the activities we do, and the food we put into our bodies. If each activity has a negative and positive effect, can we score them? Here is my effort to create the “Stone Aging Impact Score” with each activity having a negative or positive effect on a scale of minus 10 to plus 10.

Life has turned inward. The smartphone, the personal computer, streaming TV, even our counseling sessions have turned our view inward. But if you really want to see what’s inside, get outside.

The abs have it. If you could focus on only one part of your body to change and strengthen, consider spending the rest of this year on your abdominal muscles. Here is why you should—and a simple exercise for getting the abs you deserve.

Artificial Intelligence-enabled systems that interpret radiologic studies are advancing to the point where they often match the best radiologists in the world. And they are getting better every day. From CT scans to MRIs, angiograms to Doppler studies, the data captured is digital—and digital data can be read by machines.

Swimming pools are like boats and golf clubs. The average boat is used 14 days a year, as is the average set of golf clubs. They look good and are expensive, yet they are largely ignored. Here is why you should get wet.

When SF 49ers quarterback Jimmy Garappolo tore his anterior cruciate ligament on September 23rd in the second game of the 2018 season, the immediate verdict was, “He’s out for the season. He’ll be back next year.” Why does it take so long to recover from a simple ligament rupture?

I believe that no doctor should do anything to or put anything into a patient without knowing or studying the long-term outcome.

When Serena Williams was penalized during the US Open, she turned her anger against her accuser—the umpire—rather than on her opponent. She lost. At the same event, when Roger Federer suffered from the high heat and humidity he couldn’t wait to get out of the poorly designed Arthur Ashe tennis stadium. He lost.

Total knee replacement has been a godsend for many people with severe bone-on-bone arthritis. Many of my patients are skiing, hiking, and playing sports on replaced knees at levels they have not done in years, or even decades.

Gluten-free, vegan, dairy-free…all these variations of diets originally designed to address irritable bowels are exploding—apparently, because people’s bowels are now explosive. Celiac, diverticulitis, irritable bowel syndrome, and their relatives are being diagnosed more frequently than ever. As a society, Americans are becoming both more mindful and more stressed. Could these be linked through the gut?

Top skier breaks her leg. Doctor fixes it, gives her narcotics, and sends her home. She’s told to come back in two weeks for a checkup and have the rod taken out in a year. Doctor moves on to the next patient. What is wrong with this picture?

“Stretch, stretch more, do yoga, do Pilates,” our trainers encourage us in a never-ending litany. Our stiffness is hurting our backs, our knees, and our performance. But what about the too flexible athletes?

The ACL is the key stabilizer of the knee and is torn 300,000 times a year in the U.S. alone. The treatment of these torn ligaments has evolved in some ways, but not so much in others. Here is what we know today.

Exercise for fun, or for training, or both. Exercise wisely, in ways that help you in sports or your daily life. But don’t do exercises that are useless, or potentially injury-generating. Here are a few doozies that should not be on your list:

Varying medical protocols because someone is extra-special can lead to problems.
If you are extra-special, I suggest you request plain vanilla care—and expect the best outcome to occur. Here is why.

What is a woman? The question has confounded sports authorities forever. The current attempts to regulate this controversy are doomed to fail

Why is it that the fun and satisfaction of participating in sports overwhelms our recognition that they could significantly destroy our body, be it the knee or the brain?

The dreaded “hammy” is the tearing of the muscle or tendon fibers of the powerful hamstring muscles at the back of the leg. It’s dreaded because the pain is sharp, and the recovery can be long. Here is what’s known and what’s new:

You watch the ball. I watch the knees. Here is what I see:
