Osteoarthritis can’t be reversed, but a combination of exercise, weight management, medication, and supportive devices can significantly reduce pain and keep you moving. The most effective approach uses several of these strategies together, tailored to your specific joints and symptoms.
Exercise Is the Single Most Important Step
Regular exercise consistently outperforms most other interventions for osteoarthritis pain and stiffness. It strengthens the muscles that support your joints, improves flexibility, and helps maintain the cartilage you still have. Walking alone can reduce constant and intermittent knee pain by roughly 25%, and people who walk regularly over several years report 40% fewer episodes of new knee pain.
The best exercise program includes a mix of four types: strength training (like squats, leg presses, or resistance bands), aerobic activity (walking, cycling, swimming), flexibility work (stretching, yoga), and balance or coordination exercises. You don’t need to do all four every session, but rotating through them over the week gives the most benefit. Aquatic exercise is a good option if land-based movement is too painful, since water supports your body weight while still letting you build strength.
The key is adequate dosage and progression. Brief, occasional stretching won’t cut it. You need enough intensity and frequency to challenge your muscles, then gradually increase the difficulty as your body adapts. Whether you exercise in a group class, one-on-one with a physical therapist, or on your own using a digital program matters less than actually doing it consistently. Pick the format you’ll stick with.
Why Losing Even a Little Weight Matters
Every extra pound of body weight adds 3 to 6 pounds of force to your knees with each step. That means being just 10 pounds overweight puts an additional 30 to 60 pounds of pressure on your knee joints during walking. Over thousands of steps per day, that extra load accelerates cartilage breakdown and increases pain.
The flip side is encouraging: losing even a modest amount of weight meaningfully reduces joint stress. If you’re overweight or obese, combining dietary changes with exercise produces the best outcomes for both pain relief and function. An anti-inflammatory dietary pattern, like the Mediterranean diet or the DASH diet, may offer additional benefits. These eating patterns are associated with lower levels of inflammatory markers in the body and may help reduce joint pain while potentially slowing cartilage damage over time.
Topical Pain Relief Before Oral Medications
For knee osteoarthritis, topical anti-inflammatory gels or creams applied directly to the skin over the joint are now considered the preferred first-line medication. Topical diclofenac, the most studied option, has a greater than 92% probability of producing meaningful pain relief. It works locally rather than circulating through your entire body, which dramatically reduces side effects. In a large network analysis, zero out of eight topical anti-inflammatory preparations showed increased risk of adverse events compared to placebo, while about 30% of oral versions did.
When topical treatment isn’t enough, oral anti-inflammatory medications are the next step. Lower doses tend to offer a better balance of pain relief and safety. If you do need oral medications, the research suggests they are substantially safer than opioid painkillers, which showed increased adverse event risk in nearly 90% of the preparations studied. Opioids also had an 83% rate of causing side effects severe enough that people stopped taking them.
Injections and Newer Options
Corticosteroid injections directly into the joint can provide short-term relief, typically lasting a few weeks to a couple of months. They’re useful for flare-ups but aren’t a long-term solution, and repeated injections may actually harm cartilage over time.
Platelet-rich plasma (PRP) injections have emerged as a more promising option. A 2025 meta-analysis of 18 randomized controlled trials found that PRP significantly improves both pain and function compared to placebo at 6 and 12 months, with improvements that exceed the threshold for clinically meaningful change. A separate review of 35 trials reported that PRP consistently outperformed corticosteroid injections in mid-term and long-term outcomes. Higher-concentration preparations (more than 10 billion platelets per injection) appear to produce better results. The European Society of Sports Traumatology now gives PRP a grade A recommendation for knee osteoarthritis. PRP is not yet covered by most insurance plans, however, and typically costs several hundred dollars per injection.
Braces, Supports, and Assistive Devices
Unloader knee braces work by shifting pressure away from the damaged part of your joint. Biomechanical studies show these braces can reduce forces on the knee by 30 to 50% during activities that require bending, like squatting, climbing stairs, or rising from a chair. The effect is strongest at deeper bending angles, which is exactly when most people feel the most pain. Simpler options like knee sleeves provide compression and warmth, which can reduce pain and improve your sense of joint stability even if they don’t mechanically redistribute load.
Beyond braces, practical changes at home and work can make a real difference. Walking aids like a cane (used in the hand opposite the affected knee) reduce joint loading. Supportive, cushioned footwear absorbs shock. Grab bars in the bathroom, raised toilet seats, and ergonomic adjustments at your desk reduce the strain on painful joints during daily tasks.
Do Glucosamine and Chondroitin Work?
Glucosamine and chondroitin are among the most popular supplements for osteoarthritis, but the evidence is more nuanced than the marketing suggests. A network meta-analysis found that glucosamine combined with chondroitin sulfate does not produce clinically significant pain reduction in people with mild-to-moderate knee osteoarthritis. Glucosamine alone didn’t meet the threshold for meaningful improvement either.
The combinations that did show real benefit were glucosamine paired with omega-3 fatty acids and glucosamine paired with ibuprofen. Glucosamine plus omega-3 was the only combination that provided lasting long-term pain relief compared to placebo. If you’re considering supplements, adding omega-3s (from fish oil or dietary sources) may be more effective than the traditional glucosamine-chondroitin combination that most products offer.
When Joint Replacement Becomes the Right Choice
Joint replacement surgery is not a last resort chosen in desperation. It’s an elective procedure that works best when the timing is right. Research on surgical outcomes shows that the people who benefit most from knee replacement share a specific profile: they have significant knee pain and disability, they find their current symptoms unacceptable, and they’re genuinely willing to go through surgery. Fewer symptoms of depression and realistic expectations about what surgery will and won’t fix also predict better results.
People who expected surgery to improve their ability to climb stairs and participate in recreational activities tended to do well. Those who expected it to improve their psychological wellbeing or ability to kneel were more likely to be disappointed. Joint replacement reliably eliminates the grinding bone-on-bone pain that limits daily movement, but it doesn’t restore the knee to its 20-year-old self. Most replaced joints last 15 to 20 years, and recovery involves several weeks of dedicated rehabilitation.
Building a Plan That Works Together
The most important thing to understand about osteoarthritis management is that no single treatment works as well alone as several approaches work together. Current guidelines emphasize an individualized, multicomponent plan. That means combining regular exercise with weight management if needed, using topical pain relief for flare-ups, wearing supportive footwear or a brace during demanding activities, and making practical modifications to your environment.
Behavior change techniques, like setting specific goals, tracking your activity, and building exercise into your daily routine rather than treating it as a separate task, improve the odds that lifestyle changes actually stick. Education matters too: understanding that exercise is safe for arthritic joints, that some discomfort during activity is normal and not a sign of damage, and that staying active protects your joints better than resting them, changes how people approach their condition and how well they do over time.
