When you have knee pain, you just want it to go away so you can walk without having to limp or wince with every step. And a small, randomized trial published online Jan. 12, 2021, by Annals of Internal Medicine found that one type of shoe might be best for the job. Researchers took 164 people ages 50 or older with moderate or severe knee arthritis and randomly assigned half of the group to wear stable, supportive shoes with thick soles that didn't bend much. The other half was assigned flat shoes with thin, flexible soles, which are believed by some to provide a benefit by allowing more natural movement of the leg and foot. Both groups wore their assigned shoes for six hours per day and took part in activities such as walking during that time. After six months, 58% of people in the stable, supportive shoe group reported a reduction in knee pain while walking, compared with 40% of people reporting pain reduction after wearing the flat, flexible shoes. In both groups, the pain reduction probably was a benefit of regular walking. The people wearing flexible shoes were also twice as likely to develop ankle or foot pain, compared with those wearing sturdy shoes. So if you have knee pain, keep walking — in sturdy shoes.

Men may avoid activity because of their knee pain, but movement is exactly what they need.

It is perhaps the ultimate exercise catch-22: it's hard to move with knee osteoarthritis, but moving helps relieve osteoarthritis knee pain.

More than 30 million Americans have osteoarthritis, the most common kind of arthritis. While osteoarthritis can affect the hips, lower back, neck, and fingers, it occurs most often in the knees. In fact, an estimated 10% of men ages 60 and older have symptoms of knee osteoarthritis.

Treadmills and related fitness equipment can make aerobic workouts more convenient. Which type is best for you?

Even if you enjoy exercising outdoors, there are times when it's too cold, too hot, or otherwise uncomfortable or impractical to walk, jog, or cycle outside. And like many people, perhaps you've let your gym membership lapse. So how do you make sure you're getting an aerobic, heart-protecting workout most days of the week?

Maybe it's time to invest in a home exercise machine, such as a treadmill or elliptical machine. Not only can you exercise in the privacy of your home, you can also easily break up your workout into 10- to 15-minute stints throughout the day, whenever it's convenient for you. Current guidelines recommend getting at least 2.5 hours of heart rate–elevating (aerobic) exercise each week.

Ask the doctors

Q. I eat a lot of shellfish and recently developed gout in my knee. Did my diet cause the condition?

A. As you probably know, gout is a painful form of arthritis that occurs when high levels of a waste product called uric acid build up in the body. It can settle into joints, where it forms sharp crystals that can trigger inflammation, redness, and pain. Your diet may have aggravated the condition, but didn't cause it.

Ask the doctors

Q. I'm in my early 50s and am considering a knee replacement for severe arthritis. I've heard that doctors typically encourage people to wait until after age 60 to perform this procedure. Should I wait to have the surgery?

A. Doctors do sometimes recommend that people under age 60 wait to undergo a knee replacement procedure, because these artificial joints typically last only about 15 to 20 years. If someone younger gets the procedure, it's likely that the joint will need to be replaced again down the line. That said, the decision to have a joint replacement really depends more on your individual circumstances, such as how much pain you have, whether the problem is causing you significant disability, and your overall health, not just how old you are. Some people can safely wait until they are 60 to undergo the procedure without a problem. For others, waiting too long to have the knee replaced might not be advised. For example, if the knee joint deteriorates too much, that may make the surgery to replace it more challenging. Over all, most people (80% to 90%) who do opt for a knee replacement are happy with the results of the procedure, but it's best to discuss the pros and cons with your doctor.

The first line of treatment for many knee and hip problems includes taking over-the-counter pain medications. Acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen are the most common pain medication options. However, these pain medications have a variety of side effects, so it's important to discuss your personal health risks with your doctor when considering long-term use for chronic conditions such as osteoarthritis.

Acetaminophen (Tylenol and other brands) is usually effective for mild pain and is easy on the stomach. However, it is toxic to the liver at high doses. The recommended maximum per day is generally set at 4 grams (4,000 milligrams), which is the equivalent of eight extra-strength Tylenol tablets. But that dosage can still cause liver problems for some people. To be safe, aim for 3,000 milligrams or less, and be cautious of mixing multiple products containing acetaminophen, such as a pain reliever and a cold medication or a prescribed narcotic.

Strength training is good for just about everyone. It's especially beneficial for people with arthritis. When properly done as part of a larger exercise program, strength training helps them support and protect joints, not to mention ease pain, stiffness, and possibly swelling. Yet, the thought of starting a weight training program can be daunting to many arthritis sufferers.

If you have arthritis and want to incorporate strength training into your health routine, these tips can help you get started.
