There is no single best treatment for osteoarthritis. The most effective approach combines regular exercise, weight management, and pain relief tailored to the joint involved and how severe your symptoms are. International guidelines consistently recommend starting with non-drug strategies before adding medications, and most people get meaningful relief without surgery.
Exercise Is the Foundation
Exercise is the single most recommended intervention for osteoarthritis, appearing at the top of every major clinical guideline. It reduces pain, improves joint function, and strengthens the muscles that support damaged joints. The 2023 EULAR recommendations state that all people with hip or knee osteoarthritis should be offered an exercise program that includes strength training, aerobic activity, flexibility work, or neuromotor exercises, with progression tailored to their current physical function.
The pain relief from exercise is real but modest. A large overview of systematic reviews found that exercise reduced knee osteoarthritis pain by about 11 to 12 points on a 100-point scale compared to no treatment or placebo. Effects were smaller for hip osteoarthritis (about 7 points) and moderate for hand osteoarthritis (about 10 points). These numbers might sound underwhelming on their own, but exercise also improves mobility, balance, and overall quality of life in ways that a single pain score doesn’t capture.
What type of exercise matters less than doing it consistently. Land-based exercises, water-based programs, group classes, solo routines, and digitally guided sessions all show benefits. One notable finding: individually delivered exercise programs produced better short-term improvements in physical function for knee osteoarthritis than group formats. The best program is the one you’ll actually stick with. If you have access to a pool and find land-based exercise too painful, aquatic therapy is a solid alternative. If you prefer working out at home with an app, that works too.
Weight Loss Makes a Real Difference
Every extra pound of body weight translates to roughly three to four pounds of additional force on your knees with each step. For people who are overweight or obese, losing even a moderate amount of weight can significantly reduce joint pain and slow progression. Guidelines specifically recommend that people with hip or knee osteoarthritis be offered support to achieve and maintain weight loss, not just told to “eat less.” Combining dietary changes with exercise produces better results than either alone, because you’re simultaneously reducing joint load and strengthening the structures around the joint.
Topical Pain Relief Before Pills
When exercise and weight management aren’t enough on their own, the safest first medication option for knee osteoarthritis is a topical anti-inflammatory gel or cream applied directly to the skin over the affected joint. Topical anti-inflammatories (like diclofenac gel) work about as well as oral anti-inflammatory pills for improving joint function, with no statistically significant difference between them. The safety advantage is substantial: topical versions carry roughly half the risk of gastrointestinal side effects compared to oral anti-inflammatories, and they also cause fewer gut problems than acetaminophen (Tylenol).
Topical treatments work best for joints close to the skin surface, particularly knees and hands. For deeper joints like the hip, the medication doesn’t penetrate well enough, so oral options become more relevant.
Oral Medications for Broader Relief
Oral anti-inflammatory medications remain a mainstay for osteoarthritis pain that topical treatments can’t reach or don’t adequately control. They’re effective, but they come with risks that increase with prolonged use, including stomach ulcers, kidney strain, and cardiovascular concerns. The general approach is to use the lowest effective dose for the shortest time necessary.
Acetaminophen was once a go-to first choice, but the evidence has shifted. It provides less pain relief than anti-inflammatories and, somewhat surprisingly, carries its own gastrointestinal risks. It still has a role for people who can’t tolerate anti-inflammatories, but it’s no longer considered the default starting point.
For people whose pain has a nerve-sensitization component, where the joint feels more painful than the structural damage alone would explain, a prescription medication called duloxetine can help. It’s FDA-approved for chronic musculoskeletal pain and works by changing how the brain processes pain signals. It’s not appropriate for everyone: it should be avoided by people with liver disease, heavy alcohol use, or severe kidney impairment, and it can interact with anti-inflammatory drugs by increasing bleeding risk.
Injections for Flare-Ups
Corticosteroid injections directly into the joint can provide rapid relief during painful flare-ups, often within a day or two. The effect is temporary, typically lasting weeks to a few months. Current guidelines recommend limiting these injections to no more than once every three months to avoid potential cartilage damage from repeated use. They’re best thought of as a tool for getting through acute episodes rather than a long-term strategy.
Hyaluronic acid injections, which aim to supplement the joint’s natural lubricating fluid, remain controversial. Some patients report meaningful relief, but the clinical evidence is inconsistent, and many guidelines give them only a conditional recommendation.
Supplements: Limited Evidence
Glucosamine and chondroitin are among the most popular supplements for osteoarthritis, but the evidence is genuinely mixed. One Australian study of 605 participants found that taking glucosamine and chondroitin together for two years reduced joint space narrowing, a marker of cartilage loss. But a comparable U.S. study of 572 participants found no benefit for the combination, glucosamine alone, or chondroitin alone compared to placebo. Two additional studies found chondroitin alone slowed structural changes, directly contradicting the other trials.
The bottom line: some people may get a modest benefit, but the inconsistency of the data means you shouldn’t rely on supplements as your primary strategy. If you try them, give it two to three months. If you don’t notice improvement, there’s little reason to continue.
When Joint Replacement Makes Sense
Joint replacement surgery is highly effective for people with moderate to severe osteoarthritis who haven’t gotten adequate relief from non-surgical treatments. The American College of Rheumatology’s guidelines are clear on one important point: once a patient with moderate to severe osteoarthritis has genuinely tried and failed non-surgical treatment, they should proceed to surgery without delay for additional conservative measures. Waiting too long can allow muscles to weaken and function to decline, potentially leading to worse surgical outcomes.
Modern hip and knee replacements have high success rates, with most people experiencing dramatic pain reduction and improved mobility. Recovery typically takes several weeks of dedicated physical therapy, and most people return to normal daily activities within three to six months. Replacement joints generally last 15 to 20 years or more.
Building a Complete Plan
The most important takeaway from the current evidence is that osteoarthritis responds best to a layered approach. Exercise and weight management form the base. Topical pain relief gets added when needed. Oral medications or injections come in for pain that breaks through those measures. Assistive devices like walking aids, supportive footwear, and ergonomic workplace adjustments can reduce joint stress throughout the day. Surgery enters the picture only when the combination of everything else isn’t enough.
Guidelines emphasize that this plan should be individualized and revisited over time. What works when symptoms are mild may need adjustment as the condition progresses. Education and self-management skills, understanding your condition, knowing what triggers flare-ups, and learning how to pace activity, were ranked as the highest implementation priority by the EULAR task force. People who understand their osteoarthritis and actively manage it tend to do better than those who passively wait for treatments to work.
