Osteoarthritis treatment combines movement, weight management, pain relief medications, and in some cases injections or surgery. There is no cure, but the right combination of approaches can significantly reduce pain and keep you active for years. The American College of Rheumatology and Arthritis Foundation give their strongest recommendations to exercise, weight loss, anti-inflammatory medications, and self-management programs as the foundation of treatment for knee, hip, and hand osteoarthritis.
Exercise Is the Single Most Important Treatment
Exercise sits at the top of every major treatment guideline for osteoarthritis, and for good reason. Regular physical activity strengthens the muscles around your joints, improves flexibility, and reduces pain over time. A large analysis of over 4,000 patients with knee osteoarthritis found that exercise therapy reduced pain by roughly 12 points on a 100-point scale compared to no treatment. That’s a meaningful difference, roughly equivalent to what many people get from medication.
The benefits vary by joint. Knee osteoarthritis responds best to exercise, while hip osteoarthritis shows more modest improvements. Hand osteoarthritis falls somewhere in between, with noticeable pain reduction but less improvement in grip strength and function. The key is consistency. Short-term studies show clear benefits, but they fade if you stop.
What counts as exercise? A mix of three types works best: strengthening exercises (like leg presses or resistance bands), aerobic activity (walking, cycling, swimming), and flexibility or balance work. Tai chi gets a specific strong recommendation from the ACR guidelines for knee and hip osteoarthritis because it combines gentle movement with balance training. You don’t need to run marathons. Low-impact activities that you can sustain several times a week matter more than intensity.
Why Weight Loss Has an Outsized Effect
If you carry extra weight and have knee or hip osteoarthritis, losing even a modest amount can produce a surprisingly large reduction in joint stress. Research from a landmark study found that each pound of body weight lost results in a four-fold reduction in the load on your knee with every step. Lose 10 pounds, and you’re taking roughly 40 pounds of pressure off your knee joint during daily walking. Over the course of a day, that adds up to thousands of pounds of cumulative force your cartilage no longer has to absorb.
Weight loss is one of the few interventions that can both reduce pain and slow the progression of the disease. The ACR guidelines strongly recommend it for anyone with knee or hip osteoarthritis who is overweight. Even a 5 to 10 percent reduction in body weight can produce noticeable symptom improvement.
Anti-Inflammatory Medications
When exercise and weight management aren’t enough on their own, anti-inflammatory drugs are the first-line medication for osteoarthritis regardless of which joint is affected. Guidelines recommend trying a topical version first, especially for knee osteoarthritis, because it delivers the drug directly to the joint with far less absorption into the rest of your body.
A meta-analysis of over 2,000 patients found that topical and oral anti-inflammatories are equally effective at reducing pain and improving function in osteoarthritis. The topical versions come as gels or creams that you rub into the skin over the affected joint. They work well for joints close to the surface, like knees and hands, but aren’t practical for deeper joints like hips.
Oral anti-inflammatories remain the go-to pill for osteoarthritis pain across all joint locations. They’re effective, but long-term use can irritate the stomach, raise blood pressure, and affect kidney function. Your dose and duration should be the lowest amount that controls your symptoms. Acetaminophen (Tylenol) was once a standard recommendation, but recent guidelines have moved away from it because the evidence for meaningful pain relief in osteoarthritis is weak.
Injections for Flare-Ups and Beyond
Steroid injections directly into the joint are strongly recommended for knee and hip osteoarthritis, particularly during flare-ups when pain spikes. They work fast, often providing noticeable relief within days. The tradeoff is that the benefit typically fades within one to three months, and repeated injections over time may not be ideal for cartilage health.
Hyaluronic acid injections (sometimes called viscosupplementation) take a different approach. They aim to supplement the natural lubricating fluid in the joint. These injections are slower to take effect than steroids but tend to provide longer-lasting relief, with moderate benefit lasting up to six months in some patients. Steroids outperform hyaluronic acid in the first month, but hyaluronic acid pulls ahead at later time points. The ACR guidelines give hyaluronic acid a conditional (rather than strong) recommendation, reflecting mixed results across studies.
Braces, Supports, and Walking Aids
Assistive devices can make a real difference when joint instability or abnormal alignment is part of the picture. A knee brace can offload the compartment of the knee most affected by arthritis, reducing pain during walking. For thumb-base arthritis, a splint stabilizes the joint enough to let you grip and pinch with more confidence. A cane, used on the opposite side of the affected leg, reduces pressure on hip and knee joints while improving balance.
Not everyone with osteoarthritis needs a device. Guidelines from NICE recommend them specifically when there’s joint instability or abnormal alignment, and when exercise alone isn’t enough. The right device depends on your specific anatomy. Someone with inward-bowing knees might benefit from arch-support insoles, while someone with outward-bowing knees and arthritis on the inner side of the joint may do better with a lateral wedge insole or supportive shoe.
Glucosamine and Chondroitin
These are among the most popular supplements for osteoarthritis, and the evidence is more nuanced than the marketing suggests. A six-year study tracking cartilage changes in knee osteoarthritis found that the combination of glucosamine and chondroitin sulfate significantly reduced cartilage volume loss, particularly in the outer compartment of the knee. The protective effect became significant in people who took the supplements for at least two years, suggesting that any structural benefit requires long-term, consistent use.
The catch is that most guidelines give these supplements a conditional or neutral recommendation. Short-term pain relief is modest at best, and individual responses vary widely. If you’ve been taking them for a few months without noticing any change, they’re unlikely to suddenly start working. But the long-term structural data is intriguing enough that many rheumatologists don’t discourage patients who want to try them.
PRP and Stem Cell Treatments
Platelet-rich plasma (PRP) and stem cell injections are widely marketed for osteoarthritis, but the evidence remains thin. An umbrella review of multiple meta-analyses found that the vast majority of studies supporting these therapies were rated as low or critically low quality. Only 2 out of 28 included analyses earned high confidence ratings. The treatments may offer some benefit, particularly over longer follow-up periods, but the science isn’t strong enough yet to know who they help, how well they work compared to standard treatments, or how long the effects last. They’re also typically not covered by insurance.
When Joint Replacement Becomes the Right Option
Surgery isn’t first-line treatment, but for people who’ve exhausted other options, total joint replacement is one of the most effective operations in medicine. According to the American Academy of Orthopaedic Surgeons, it’s typically considered when you have chronic inflammation and swelling that doesn’t improve with rest or medications, visible joint deformity (like bowing of the knee), or when anti-inflammatory drugs, injections, physical therapy, and other treatments have all failed to provide adequate relief.
Most people who get a knee or hip replacement experience dramatic pain reduction and return to activities like walking, gardening, and light sports. Modern implants last 15 to 20 years or more in most patients. Recovery typically takes several months of physical therapy, with the biggest improvements happening in the first three months and continued gains over the first year.
Putting a Treatment Plan Together
Osteoarthritis treatment works best as a layered approach. The foundation is always exercise, weight management if needed, and learning to pace your activities. Medications and topical treatments add pain control on top of that. Braces or walking aids address mechanical problems. Injections help manage flare-ups or provide medium-term relief. Surgery is reserved for joints that no longer respond to anything else.
What matters most is finding the combination that keeps you moving. Osteoarthritis tends to create a cycle where pain leads to inactivity, which leads to weaker muscles and stiffer joints, which leads to more pain. Every effective treatment aims to break that cycle from a different angle. Starting with the least invasive options and building from there gives you the most tools to work with over time.
