Moving away from knee osteoarthritis
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.
Where to turn for pain relief - acetaminophen or NSAIDs?
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.
Steroid injections do little for long-term knee osteoarthritis pain
In the journals
Corticosteroid injections are used to ease short-term knee osteoarthritis pain, but a new study in the May 16, 2017, Journal of the American Medical Association suggests the treatment may not help in the long term.
Researchers recruited two groups of 70 people, average age 58, with knee osteoarthritis. One group received 40 milligrams of the steroid triamcinolone (Kenacort, Kenalog, Artistocort) every three months for two years, while the other group got placebo injections. By the end, pain scores — measured on a scale from zero for no pain to 20 for extreme pain — had dropped by only 1.2 points among the steroid group, while the placebo group's score dropped by 1.9 points, neither of which was clinically significant.
Will a knee replacement really make life better?

Many older adults have pain from knee osteoarthritis, a condition in which cartilage in the joints wears away. But when is it time for joint replacement? An observational study published March 28, 2017, in The BMJ suggests that a new knee improves quality of life only in certain cases. The study included over 7,400 middle-age and older adults who already had knee arthritis or were at high risk for the condition. Compared with people who didn't have knee replacement, those who had the surgery during the 26-year study period appeared to have a better quality of life afterward. However, the improvements were minimal, except in people who were less physically functional before the surgery because of more severe arthritis symptoms. The authors suggest that the high costs of knee replacement may be justified only in those who are severely affected by arthritis. What if your symptoms aren't severe? As we reported last month, it may be possible to delay or avoid knee surgery by strengthening your leg and core muscles, losing weight, and improving range of motion.
Age-proof your knees
Improving range of motion, muscle strength, and weight control can help reduce pain and make your knees feel younger.

Knee pain is common in older age, often caused by osteoarthritis (the wearing away of knee cartilage). Fortunately, there are ways to fool Father Time and postpone knee problems or even prevent them entirely. "In many cases, you can delay or avoid the need for surgical intervention, such as a knee replacement," says Dr. Lars Richardson, an orthopedic surgeon with Harvard-affiliated Massachusetts General Hospital.
The aging knee
Your knees absorb a huge amount of pressure with every step — typically one-and-a-half times your body weight. That pressure, plus regular wear and tear, takes a toll over time. Muscles and ligaments get weaker. The knee's two shock absorbers — pads of cartilage called menisci — start to deteriorate. So does the articular cartilage protecting the ends of the leg bones where they meet at the knee. If you have a family history of osteoarthritis, if you're overweight, or if you've had some knee injuries, you may be more prone to this deterioration.
X-ray may be best screening tool for diagnosing knee pain
A simple x-ray may be a better and cheaper way to diagnose knee arthritis than an MRI, according to researchers. X-rays are also cheaper than MRIs and quicker to perform.
Can the right shoes relieve knee pain?
It appears that “unloading” shoes are no better at reducing pain or improving function than a good pair of walking shoes, according to a study published online July 12, 2016, by Annals of Internal Medicine.

Knee pain is one of the top reasons men visit their doctor. While the pain and soreness often can go away with rest, ice, and over-the-counter pain medications, if it becomes too severe or fails to abate in a timely manner, you may need to take further action.
"If your knee pain is not a result of some kind of structural or mechanical issue that requires surgery, or due to osteoarthritis, there are other options that may help eliminate or better control the pain," says Dr. Lars Richardson, a sports medicine orthopedic surgeon with Harvard-affiliated Massachusetts General Hospital.
Why weight matters when it comes to joint pain
If you're having the occasional twinge of joint pain when you go for a walk or climb stairs, or you're worried about arthritis because a parent had it, one step toward prevention is to check your weight.
There are two ways that being overweight raises your risk for developing osteoarthritis (the most common joint disorder, which is due to wear and tear on a joint). First, excess weight puts additional stress on weight-bearing joints (the knee, for example). Second, inflammatory factors associated with weight gain might contribute to trouble in other joints (for example, the hands).
Ask the doctor: Braces for knee arthritis

Ask the doctor
Q. I occasionally use a brace on my knee because I have knee arthritis. Am I weakening my knee?
A. The benefit of a brace for knee arthritis is likely in the eye of the beholder. A brace can help improve the ability to perform certain activities, and for some people the compression and warmth of the brace relieves pain. However, medical research has been mixed on the absolute benefits.
