Arthritis treatment depends on the type you have, but nearly all approaches combine some form of pain management, strategies to protect the joint, and lifestyle changes that slow progression. Osteoarthritis and rheumatoid arthritis are the two most common forms, and while they share symptoms like pain and stiffness, their treatments diverge significantly because the underlying causes are different. Osteoarthritis is driven by mechanical wear and inflammation in the joint itself, while rheumatoid arthritis is an autoimmune disease where the immune system attacks joint tissue.
Pain Relief and Anti-Inflammatory Medications
For both osteoarthritis and rheumatoid arthritis, over-the-counter anti-inflammatory drugs are typically the first line of defense. Ibuprofen and naproxen reduce pain and swelling by blocking the enzymes that drive inflammation. Over-the-counter daily limits are 1,200 mg for ibuprofen and 660 mg for naproxen sodium, though doctors sometimes prescribe higher doses for chronic arthritis under close monitoring. Acetaminophen helps with pain but doesn’t address inflammation, so it’s less useful when swelling is a major part of the picture.
These medications work well for flare-ups and mild to moderate daily symptoms, but long-term use carries risks. Stomach ulcers, kidney problems, and increased cardiovascular risk all become concerns with chronic use. Topical versions applied directly to the skin over the affected joint can reduce those systemic risks while still providing local relief, and they’re a good option for hand or knee arthritis where the joint is close to the surface.
Disease-Modifying Drugs for Rheumatoid Arthritis
If you have rheumatoid arthritis, the goal isn’t just managing pain. It’s stopping the immune system from destroying your joints. Treatment guidelines recommend starting with conventional disease-modifying drugs (DMARDs) as early as possible after diagnosis. Methotrexate is the standard first choice. It suppresses the overactive immune response and, for many people, slows or halts joint damage when started early enough.
When methotrexate alone isn’t enough, doctors add or switch to biologic drugs. These are more targeted therapies delivered by injection or infusion. The most widely used class blocks a protein called TNF-alpha, one of the key drivers of joint inflammation in RA. Other biologics target different parts of the immune cascade, like the signaling protein IL-6, which plays a broad role in fueling the inflammatory response throughout the body. Finding the right combination can take time. Research tracking real-world treatment patterns found that the path to a successful drug regimen is often long, with patients trying multiple medications. The median time to reach certain biologic therapies was over 17 months from the start of treatment, and some patients cycled through six or more drugs before finding one that worked.
JAK Inhibitors
A newer class of oral medications works by blocking enzymes inside immune cells that transmit inflammatory signals. Three of these drugs are approved for rheumatoid arthritis. Unlike biologics, they come as pills rather than injections, which is a significant practical advantage. However, the FDA added its strongest safety warning to all three after a large clinical trial found higher rates of serious heart events, blood clots, and certain cancers compared to TNF-blocking biologics. The cancer risk was particularly notable for lymphoma and, among current or past smokers, lung cancer. Because of these findings, these medications are generally reserved for people who haven’t responded adequately to other treatments.
Joint Injections
When arthritis pain concentrates in a single joint, particularly the knee, injections directly into the joint space can provide relief that oral medications can’t match. The two main options work on different timelines. Corticosteroid injections deliver powerful anti-inflammatory medication straight to the source of pain. They tend to work quickly and provide the strongest relief in the first month, but the effect fades. Doctors typically limit how often you can receive them because repeated steroid injections may accelerate cartilage breakdown over time.
Hyaluronic acid injections take a different approach. Hyaluronic acid is a natural component of joint fluid that acts as a lubricant and shock absorber. Injecting a synthetic version aims to restore some of that cushioning. The relief takes longer to kick in compared to steroids, but studies show better results at the six-month mark. Repeat courses of hyaluronic acid have also been shown to be safe and effective after an initial round, making them a reasonable option for people looking for longer-term management without surgery.
How Weight Loss Changes Joint Pressure
Losing weight is one of the most impactful things you can do for knee or hip osteoarthritis, and the math behind it is striking. Research measuring actual forces on the knee found that every pound of body weight lost translates to a four-pound reduction in the load on your knee with each step. That might sound modest until you consider that the average person takes several thousand steps a day. Losing even 10 pounds removes roughly 40 pounds of force per step, adding up to tens of thousands of pounds of reduced stress on your knees over the course of a single day.
The study also found that weight loss reduced the twisting forces on the knee, not just the downward compression. This matters because those rotational loads are thought to accelerate cartilage wear on the inner side of the knee, where osteoarthritis most commonly strikes.
Physical Therapy and Exercise
Exercise is consistently one of the most effective treatments for arthritis, even though it’s the one people are most hesitant to try. The concern that movement will worsen joint damage is understandable but largely unfounded for appropriate, moderate activity. Strengthening the muscles around an arthritic joint stabilizes it and absorbs forces that would otherwise go straight into damaged cartilage.
Physical therapy programs for arthritis typically focus on three elements: range-of-motion exercises to maintain flexibility, strengthening exercises for the muscles supporting the joint, and low-impact aerobic activity like swimming, cycling, or walking. Water-based exercise is particularly useful because buoyancy reduces joint loading while the water provides gentle resistance for strengthening. The benefits extend beyond the joint itself. Regular exercise reduces the systemic inflammation that contributes to both osteoarthritis and rheumatoid arthritis, improves sleep, and counteracts the fatigue that both conditions cause.
Supplements With Clinical Evidence
Most arthritis supplements have weak or conflicting evidence, but curcumin (the active compound in turmeric) is a notable exception. A meta-analysis of randomized clinical trials found that roughly 1,000 mg per day of curcumin significantly reduced pain scores and improved joint function in people with arthritis. The pain reduction was substantial, and pooled results from five studies suggested curcumin’s effects were not statistically different from those of standard pain medications like ibuprofen. Study dosages ranged from 500 mg taken twice daily to 1,500 mg per day, often combined with black pepper extract to improve absorption.
Omega-3 fatty acids from fish oil also have reasonable evidence for reducing joint stiffness and tenderness in rheumatoid arthritis, primarily by dampening the inflammatory pathways the immune system uses to attack joint tissue. Neither supplement replaces medical treatment for RA, but both may complement it.
When Surgery Becomes the Best Option
Joint replacement is the definitive treatment for arthritis that hasn’t responded to other approaches, and modern outcomes are excellent. According to the UK’s National Joint Registry, which tracks over a million procedures, only 2.7% of hip replacements performed in 2014 needed revision surgery within 10 years. For knee replacements, the 20-year revision rate was just 5.28% across more than one million procedures. That means roughly 95 out of 100 knee replacements are still functioning two decades later.
Most people who reach the point of considering surgery have already tried medications, injections, physical therapy, and lifestyle changes. The typical signal that it’s time is when pain significantly limits daily activities like walking, climbing stairs, or sleeping, and less invasive treatments no longer provide adequate relief. Recovery from hip or knee replacement generally involves several weeks of reduced mobility followed by months of physical therapy, with most people returning to full daily activities within three to six months. The replaced joint won’t feel identical to a natural one, but for most people, the reduction in pain is dramatic.
Less extensive surgical options also exist for earlier-stage disease. Arthroscopic procedures can clean out loose cartilage fragments, and osteotomy (reshaping the bone to shift weight away from the damaged area) can buy time for younger patients who aren’t yet candidates for a full replacement.
