Osteoarthritis can’t be cured or reversed, but it can be managed well enough that many people significantly reduce their pain and get back to activities they’d given up on. There are no disease-modifying drugs available yet, so the most effective approach combines several strategies: targeted exercise, weight management, the right pain relievers, and in some cases injections or surgery. The people who get the best results treat it as a long-term project rather than looking for a single fix.
Exercise Is the Single Most Effective Treatment
If there’s one thing that consistently outperforms everything else for osteoarthritis pain and mobility, it’s structured exercise. A Cochrane review of 44 randomized controlled trials found moderate improvements in both pain and physical function from exercise programs. That’s a comparable effect size to many pain medications, without the side effects.
The GLA:D program, a structured approach involving patient education sessions and 12 supervised exercise sessions over eight weeks, has been studied in over 28,000 people with knee or hip osteoarthritis across Denmark, Canada, and Australia. Participants improved 26 to 33% in pain intensity, 8 to 12% in walking speed, and 18 to 30% in their ability to rise from a chair. Roughly 43 to 47% of patients experienced pain reductions large enough to be clinically meaningful.
The best exercise program is one you’ll actually stick with. Strength training, aerobic exercise, flexibility work, and balance-focused (neuromotor) exercises all help. You can do them on land or in water, individually or in a group, supervised or on your own, even through a digital program. What matters is that the exercises are progressively challenging and done consistently. Starting too aggressively often backfires. A physical therapist can help you find the right starting point and build from there.
Why Weight Loss Matters More Than You’d Think
Every extra 10 pounds you carry increases the force on your knee by 30 to 60 pounds with each step. That math adds up fast over the thousands of steps you take daily, accelerating cartilage breakdown and driving pain.
A reasonable initial goal is losing 10% of your body weight. Research from Johns Hopkins shows that even modest weight loss substantially reduces pain reports. If you hit that 10% target and feel good about the process, further loss can add more benefit. The combination of weight loss and exercise tends to produce better results than either one alone, because you’re simultaneously reducing the load on the joint and strengthening the muscles that support it.
Medications That Help With Pain
For knee osteoarthritis specifically, topical anti-inflammatory gels and creams (like diclofenac gel) are the safest first option. A network meta-analysis comparing pain relievers found that topical anti-inflammatories are safer than both oral anti-inflammatories and acetaminophen, based on clinical trial and real-world data. The international OARSI guidelines only strongly recommend topical anti-inflammatories among all medication options.
Oral anti-inflammatories like ibuprofen and naproxen are effective for pain relief but carry risks to the stomach, kidneys, and cardiovascular system, especially with long-term use. Most guidelines recommend them but with more caution. Acetaminophen (Tylenol), once a go-to recommendation, has fallen out of favor. Both American and international guidelines now conditionally recommend against it or are unable to recommend it for osteoarthritis, as the evidence for meaningful pain relief is weak.
Joint Injections: What to Expect
Corticosteroid injections deliver a powerful anti-inflammatory directly into the joint. They can provide noticeable relief within days, but the effect is temporary, typically lasting weeks to a few months. They’re useful for flare-ups or when you need short-term relief to participate in physical therapy, but they aren’t a long-term solution. Repeated injections over time may actually harm cartilage.
Hyaluronic acid injections, sometimes called viscosupplementation, aim to restore some of the joint’s natural lubrication. These are given as a series of weekly injections. Head-to-head comparisons with corticosteroid injections have shown no significant difference in outcomes at three or six months. Some people find them helpful, but the evidence is mixed enough that guidelines vary on whether to recommend them.
PRP and Stem Cell Therapy
Platelet-rich plasma (PRP) injections use concentrated components of your own blood to try to promote healing in the joint. Studies suggest PRP can achieve roughly a 60% success rate for pain relief and improved knee function. That also means 30 to 40% of patients don’t experience significant benefit.
The research base is still thin. A recent scoping review found only three studies (with sample sizes ranging from 17 to 32 participants) examining PRP combined with exercise therapy, and most had notable methodological problems like lack of blinding. For stem cell therapy, the clinical evidence is even more limited. These treatments are typically not covered by insurance and can cost thousands of dollars per session.
Do Glucosamine and Chondroitin Work?
The honest answer is: maybe, but the evidence is frustratingly inconsistent. Two large two-year trials produced directly conflicting results. An Australian study of 605 participants found that taking glucosamine and chondroitin together reduced joint space narrowing (a marker of cartilage loss). A U.S. study of 572 participants found no difference between the supplements and a placebo. Two additional studies of chondroitin alone (with 622 and 300 participants respectively) found improvements in joint space, but those findings conflict with the larger trials that showed no effect for chondroitin on its own.
If you want to try them, the risk is low since side effects are minimal. But set realistic expectations. The NIH’s National Center for Complementary and Integrative Health concludes that whether these supplements actually affect joint structure remains uncertain.
Diet and Inflammation
What you eat influences the level of inflammation throughout your body, and osteoarthritis is partly an inflammatory condition. Diets rich in omega-3 fatty acids (found in fatty fish, walnuts, and flaxseed) and B vitamins tend to push the body toward lower inflammation. Diets heavy in processed foods, refined sugars, and saturated fats push it the other direction.
Research links pro-inflammatory diets not just to worse joint symptoms but to poorer sleep, greater fatigue, and lower quality of life in people with knee osteoarthritis. You don’t need to follow a rigid plan. A Mediterranean-style diet, rich in vegetables, fruit, fish, olive oil, and whole grains, captures most of the anti-inflammatory benefit.
Braces, Shoes, and Assistive Devices
Practical modifications can meaningfully reduce daily pain. Unloader braces shift pressure away from the damaged side of the knee joint, which can make walking and standing more comfortable. Supportive, well-cushioned shoes (or shoe inserts) reduce impact forces. A walking stick or cane, used on the opposite side of the affected joint, takes a surprising amount of load off with each step.
Home and workplace adaptations matter too. Raised toilet seats, handrails, ergonomic chairs, and avoiding prolonged kneeling or squatting can reduce the number of painful moments in your day. These changes aren’t glamorous, but they protect the joint during the hours you’re not exercising.
When Joint Replacement Becomes the Right Call
Joint replacement surgery, most commonly for knees and hips, is highly effective when osteoarthritis has progressed to the point where conservative measures no longer provide adequate relief. Modern knee and hip replacements have success rates above 90% for significant pain reduction, and most implants last 15 to 20 years or longer.
Surgery makes sense when pain consistently disrupts sleep, limits your ability to walk short distances, or prevents you from doing basic daily activities despite months of committed exercise, weight management, and appropriate medication. It’s not a failure of other treatments. It’s a tool best used when the joint damage has simply progressed beyond what non-surgical approaches can address. Most people wish they’d done it sooner.
Putting It All Together
The most effective approach to osteoarthritis stacks multiple strategies rather than relying on any single one. Current guidelines recommend an individualized, multicomponent plan that combines exercise, education, weight management, appropriate pain relief, and practical modifications to your daily environment. Behavior change techniques, like setting specific goals, tracking progress, and building habits gradually, help these changes stick over the long term.
The key insight is that osteoarthritis management is active, not passive. Waiting for a pill or injection to fix the problem produces worse outcomes than building a stronger, lighter, better-supported body around the affected joint. The earlier you start, the more function you preserve.
