Annually, about 790,000 Americans (about 60% women) undergo knee replacement surgery. Women are more likely to have arthritis, the main culprit leading to most knee replacements. Before surgery becomes an option, people first need to try conservative treatments such as pain relievers, injectable medications, and physical therapy. Signs a knee replacement may be necessary include pain that hinders people from doing basic activities, unstable walking, and needing multiple medications to function.

Older adults typically sit for about 65% to 80% of their waking hours. One problem of prolonged sitting is pain due to gluteal amnesia. It occurs from a weak gluteus medius-one of the three gluteal muscles that help stabilize the pelvis and maintain the body's proper alignment. Moving more often during the day and doing exercises that strengthen weak gluteal muscles can help prevent this problem.

Osteopenia is the precursor stage to osteoporosis (weak, thin bones that break easily). Ways to treat osteopenia include taking medications that slow bone loss and reduce fracture risk, exercising, eating protein- and calcium-rich foods, taking a calcium supplement to make up for a lack of dietary calcium, taking a vitamin D₃ supplement to help absorb calcium, and avoiding excessive alcohol intake. Vibration therapy (standing on a small vibrating platform) is not yet proven to be effective.

Many people who develop rheumatoid arthritis later in life don't receive optimal medications to treat it, called disease-modifying antirheumatic drugs (DMARDs). Reasons for this include the high costs of DMARDs, concerns about drug side effects, coexisting conditions that complicate treatment, inaccessibility to health care, or perceived frailty that makes doctors nervous about prescribing DMARDs. People who feel they should be getting DMARDs (but aren't) should ask about ways to make such treatment feasible.

A growing number of people ages 60 and older suffer from knee osteoarthritis. If lifestyle strategies, such as weight loss, physical therapy, exercise, and oral or topical medications don't offer sufficient pain relief, people may benefit from either corticosteroid or hyaluronic acid injections. Injections can provide immediate pain relief, reduce inflammation, and increase mobility. However, they are a temporary treatment that won't cure knee osteoarthritis or change the course of the disease.

Osteoarthritis affects more women than men. Risk factors include earlier joint injuries, obesity, diabetes, heart disease, or family history. People can try to prevent arthritis by staying physically active, maintaining a healthy weight, and engaging in low-impact exercise.

People with arthritis often avoid exercise because of their painful joints. However, exercise is one of the best ways to manage their symptoms, stay active, and improve their quality of life. Specific exercise routines can be designed around a person's type of arthritis, severity, and location, but usually focus on three areas: stretching, strength training, and low-impact aerobics.

A gentle form of soccer called walking soccer is packed with health benefits. It's a great way to socialize, exercise, and keep knee cartilage healthy. Playing the game also helps reinforce a person's ability to maintain balance and the ability to produce physical power, such as the force needed to get out of a chair and stand up. However, the game does pose some physical risks, such as ankle sprains, flare-ups of knee arthritis, and falls that result in wrist, arm, or elbow fractures.
