People with knee osteoarthritis often gain temporary pain relief from joint injections. However, there is uncertainty about long-term risks of steroid injections. A 2022 study suggests that the risk may be minimal if these injections are done infrequently.

Platelet-rich plasma injections are used to reduce pain and speed healing for a number of common problems that affect the tendons, muscles, and joints, ranging from arthritis to shoulder pain. But a growing body of research shows that they may not be effective for some conditions, including knee osteoarthritis, ankle osteoarthritis, and Achilles tendinitis. There is some evidence that it may be effective for lateral epicondylitis (tennis elbow). People should consider whether there is a better option before undergoing PRP injections.

Osteoarthritis (OA) is the number one cause of chronic knee pain, affecting nearly a quarter of people 40 or older. A recent study of people with overweight or obesity and OA showed that telehealth visits can be an effective way to provide care and may even help with weight loss, which can improve symptoms and prevent OA from worsening.

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.

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.

These painful flare-ups can occur suddenly and for no apparent reason. Here's what you can do about them.

Have you ever woken up with a mysterious egg-shaped swelling on your elbow or knee and have no clue what caused it? There is a good chance you have bursitis.

"Bursitis is definitely more common as you get older and just comes with the territory of living a longer and more active life," says Dr. Robert Shmerling, senior faculty editor at Harvard Health Publishing and Corresponding Member of the Faculty of Medicine at Harvard Medical School.
