What to Know About Osteoarthritis and Joint Pain: Updated Guidance for Staying Active in 2026

Practical takeaway: If you live with joint pain—especially from osteoarthritis—staying physically active, managing weight, and using a mix of non-drug and medication options remain the foundation of care in 2026. Surgery is helpful for some people, but most joint problems start with simpler, evidence-based steps.

Osteoarthritis Is Still the Most Common Joint Disorder

Osteoarthritis (OA) is the most common form of arthritis in the United States. According to the Centers for Disease Control and Prevention (CDC), millions of U.S. adults live with arthritis, and osteoarthritis accounts for the majority of cases. It most often affects the knees, hips, hands, and spine.

Osteoarthritis happens when the protective cartilage that cushions the ends of bones gradually breaks down. Over time, this can lead to pain, stiffness, swelling, and reduced range of motion.

It is more common with aging, but it is not simply “wear and tear.” Risk is also shaped by:

Prior joint injury (including sports injuries)
Excess body weight
Family history
Repetitive joint stress at work
Muscle weakness around the joint

What the Evidence Says About First-Line Treatment

Major U.S. and international guidelines—including those summarized by the CDC and the National Institutes of Health (NIH)—continue to emphasize that treatment for osteoarthritis should start with non-drug approaches whenever possible.

1. Physical Activity Is Core Treatment

Regular, low-impact exercise is one of the most consistently supported interventions in clinical research. Systematic reviews and guideline panels have found that activities such as walking, swimming, cycling, and strength training can:

Reduce joint pain
Improve function
Strengthen muscles that stabilize joints
Reduce fall risk

The CDC recommends at least 150 minutes per week of moderate physical activity for adults, but even smaller amounts can help if pain limits movement. The key is consistency, not intensity.

Important limitation: Exercise does not reverse cartilage loss. It helps manage symptoms and function, not cure the condition.

2. Weight Management Reduces Joint Stress

For people with knee or hip osteoarthritis, weight loss can significantly reduce pain. Research shows that even modest weight reduction can lower stress across weight-bearing joints.

This is particularly important because obesity increases both the mechanical load on joints and systemic inflammation, which may worsen symptoms.

3. Physical Therapy and Targeted Strengthening

Structured physical therapy can improve alignment, balance, and muscle strength. Strengthening the quadriceps (front thigh muscles), for example, can reduce knee pain in many patients.

Insurance coverage varies, so patients should check with their plan. Medicare typically covers medically necessary physical therapy with documentation from a healthcare provider.

When Medications Are Used

When non-drug approaches are not enough, medications may be added. According to NIH and guideline reviews published in journals such as JAMA Network and The Lancet, commonly used options include:

Topical nonsteroidal anti-inflammatory drugs (NSAIDs) for knee or hand OA
Oral NSAIDs for short-term symptom relief
In selected cases, joint injections

What to know: NSAIDs can increase the risk of stomach bleeding, kidney problems, and cardiovascular events, especially in older adults or those with heart disease. They should be used at the lowest effective dose for the shortest time needed.

Opioids are generally not recommended for chronic osteoarthritis pain because risks often outweigh benefits.

Joint Replacement: When Is Surgery Considered?

Total knee and hip replacement remain highly effective for people with severe joint damage who do not improve with conservative care. Studies published in major medical journals show strong improvements in pain and quality of life after surgery.

However, surgery involves recovery time, possible complications, and costs. Decisions should be individualized, especially for older adults or those with other medical conditions.

Other Joint Conditions to Keep in Mind

Not all joint pain is osteoarthritis. Other causes include:

Rheumatoid arthritis (an autoimmune condition)
Gout (caused by uric acid crystal buildup)
Post-infectious arthritis
Lyme disease–related joint inflammation in certain regions of the U.S.

Red flags that warrant medical evaluation include:

Sudden severe swelling
Fever with joint pain
Joint redness and warmth
Unexplained weight loss
Morning stiffness lasting more than an hour

Oral Health and Joint Health: Is There a Connection?

Research continues to explore links between chronic gum disease and systemic inflammation. While gum disease does not cause osteoarthritis, maintaining good oral health may help reduce overall inflammatory burden in the body. The NIH notes that systemic inflammation plays a role in several chronic conditions.

Good oral hygiene, regular dental care, and management of chronic disease are part of whole-person health.

Access and Equity Considerations

Arthritis-related disability affects work, caregiving, and daily activities. According to the CDC, arthritis is a leading cause of work limitation in the United States.

Barriers to care may include:

Limited access to physical therapy in rural areas
High out-of-pocket costs for injections or surgery
Transportation challenges for older adults

Community-based exercise programs, including evidence-based arthritis self-management programs recognized by public health agencies, can help bridge some of these gaps.

What This Means for Readers

If you are experiencing ongoing joint pain:

Start with movement, not rest.
Strengthen the muscles around the joint.
Talk to a clinician before relying on long-term medication.
Seek evaluation if symptoms are severe, sudden, or unusual.

Osteoarthritis is common, but disability is not inevitable. Evidence-based self-care, early evaluation, and thoughtful use of therapies can help many people maintain mobility and independence well into later life.

As always, decisions about treatment should be made in consultation with a licensed healthcare professional who understands your full medical history.
