Osteoarthritis treatment combines exercise, weight management, and pain medication, with joint replacement reserved for severe cases that don’t respond to these measures. There is no cure, but the right combination of approaches can meaningfully reduce pain and keep you moving for years.
Exercise and Physical Activity
Regular movement is the single most consistently recommended treatment for osteoarthritis, regardless of which joint is affected or how advanced the disease is. That might sound counterintuitive when your knee or hip hurts, but strengthening the muscles around a joint reduces the load on damaged cartilage, improves stability, and often lowers pain levels within weeks.
A structured physical therapy program typically involves up to eight visits over four months, during which a therapist designs exercises tailored to your joint, your fitness level, and your goals. The program usually includes a mix of strengthening work (like leg presses or resistance bands), flexibility exercises, and low-impact aerobic activity such as walking, swimming, or cycling. You don’t need to commit to intense workouts. Consistency matters more than intensity, and most benefits come from doing your exercises regularly at home between sessions.
Weight Management
Every extra pound of body weight translates to roughly three to four additional pounds of force on the knee with each step. For people who are overweight, losing weight is one of the most effective things they can do to slow joint damage and reduce pain. A 2025 meta-analysis of weight loss trials in knee osteoarthritis found that significant pain relief kicked in once patients lost at least 7.4% of their body weight. For someone weighing 200 pounds, that’s about 15 pounds.
How you lose the weight matters less than reaching that threshold. Combinations of diet changes and exercise programs showed the strongest results, but any approach that gets you past that mark is likely to produce noticeable improvement in both pain and physical function.
Topical Medications
For knee and hand osteoarthritis, topical anti-inflammatory gels and creams applied directly to the skin over the joint are a strong first option. These contain the same active ingredients as oral anti-inflammatory pills but deliver them locally, which dramatically reduces side effects. In a large network meta-analysis, topical anti-inflammatories matched oral versions for improving joint function but carried roughly half the risk of gastrointestinal problems. Real-world data from over 22,000 patients showed topical versions also had lower rates of cardiovascular events and GI bleeding over a full year of use.
Capsaicin cream, derived from chili peppers, is another topical option that works by gradually desensitizing pain-signaling nerve fibers in the skin. It can cause a burning sensation for the first week or two, which fades with continued use.
Oral Pain Medications
When topical treatments aren’t enough on their own, oral anti-inflammatory medications (NSAIDs like ibuprofen or naproxen) are the standard next step. Current guidelines rank them as more effective than acetaminophen (Tylenol), which performs poorly in rigorous testing. When researchers looked at only high-quality trials, acetaminophen’s pain relief effect was so small it was no longer statistically distinguishable from a placebo.
The tradeoff with oral anti-inflammatories is their side effect profile. They can irritate the stomach lining, raise blood pressure, and strain the kidneys, especially with long-term use. The guiding principle is to use the lowest dose that controls your pain for the shortest stretch of time you need it. For people with heart disease, kidney problems, or a history of stomach ulcers, acetaminophen may still be the safer choice despite its limited effectiveness, simply because the alternatives carry greater risks.
Opioid painkillers are not recommended for osteoarthritis. The risks of dependence, sedation, and falls outweigh the modest pain relief they provide for this type of chronic joint pain.
When Pain Has a Nerve Component
Some people with osteoarthritis develop pain that feels out of proportion to the joint damage visible on imaging, or pain that has a burning, shooting quality. This happens when the nervous system becomes sensitized after months or years of chronic pain signals. In these cases, a medication called duloxetine can help. It works by boosting levels of two chemical messengers (serotonin and norepinephrine) in the brain and spinal cord, which strengthens the body’s built-in pain-dampening systems. It’s typically started at a low dose for the first week, then increased to a maintenance dose. It’s used alongside other treatments rather than as a standalone option.
Cortisone Injections
Corticosteroid injections directly into the joint can provide fast, significant pain relief that lasts several weeks to a few months. They’re useful for flare-ups or when you need a window of reduced pain to start an exercise program. The catch is that the relief is temporary, and there’s growing evidence that repeated injections may accelerate cartilage loss over time. Most doctors limit injections to no more than three or four per year in the same joint, and some are more conservative than that.
These injections work best as an occasional tool rather than an ongoing treatment strategy.
Treatments That Don’t Work
Several popular treatments for osteoarthritis lack evidence of meaningful benefit. Glucosamine and chondroitin supplements are widely sold and used, but the American College of Rheumatology, the Arthritis Foundation, and the Osteoarthritis Research Society International all strongly recommend against them for knee osteoarthritis. The best-designed studies show inconsistent results at best, and the major guidelines conclude there’s no reliable benefit. The European view is slightly more favorable toward one specific pharmaceutical-grade form of glucosamine sulfate, but that formulation isn’t what’s typically sold over the counter.
Platelet-rich plasma (PRP) injections, stem cell treatments, and hyaluronic acid injections are also not recommended by current Australian clinical standards for knee osteoarthritis. Hyaluronic acid injections occupy a gray zone: most published reviews show a statistically significant effect on pain, but the improvement is often small enough that some guideline panels consider it clinically irrelevant. Fish oil, medicinal cannabis, and nerve-pain drugs like gabapentin similarly lack sufficient evidence for osteoarthritis.
Arthroscopic surgery to “clean out” the knee (debridement or partial meniscectomy) provides little to no meaningful improvement in pain or function for uncomplicated osteoarthritis and is no longer recommended as a treatment.
Joint Replacement Surgery
When pain persists despite months of optimal nonsurgical treatment, joint replacement becomes a reasonable option. The typical indicators that it’s time to consider surgery include pain that wakes you at night, inability to walk more than a few blocks, or joint pain that prevents you from working or doing basic daily activities after at least six months of appropriate medication and exercise.
Total knee and hip replacements are among the most successful elective surgeries performed today. Most artificial joints last 15 to 20 years or longer. Recovery involves several weeks of limited mobility followed by months of physical therapy, but the majority of patients report substantially less pain and better function than they had before surgery. Joint-conserving procedures, such as osteotomy (realigning the bone to shift weight off the damaged area), may be an option for younger patients or those with damage limited to one part of the joint.
Putting a Treatment Plan Together
Osteoarthritis management works best as a layered approach. Exercise and weight management form the foundation and should continue at every stage of the disease. Topical anti-inflammatories are added for localized pain, with oral medications brought in when needed. Cortisone injections can handle flare-ups. Surgery enters the picture only after these measures have been given a genuine, sustained effort. The goal isn’t to eliminate arthritis, which isn’t possible, but to find the combination that keeps your pain manageable and your joints functional for as long as possible.
