Osteoarthritis is managed through a combination of movement, weight control, pain relief strategies, and supportive devices, with surgery reserved for advanced cases that don’t respond to these approaches. No single treatment works on its own. The most effective plans layer several strategies together, tailored to which joints are affected and how much they limit your daily life.
Exercise Is the Single Most Important Treatment
Every major medical guideline strongly recommends exercise as a first-line treatment for knee and hip osteoarthritis. Walking, strengthening exercises, aquatic exercise, and neuromuscular training all work, with no evidence that one type outperforms another. The key is consistency and finding something you’ll stick with.
Strength training deserves special attention. A large meta-analysis found a dose-response relationship: pain relief improves as you do more resistance training per week, up to an optimal point. For most people, that sweet spot translates to roughly two to four sessions per week, each lasting 50 to 75 minutes, using bodyweight exercises like squats, lunges, and push-ups. Going beyond that optimal dose actually starts to diminish the benefit, so more is not always better. If you prefer working with weights at a higher intensity, two sessions of about 60 minutes each per week can reach the same target.
Tai chi and yoga both have enough evidence behind them to be recommended, with tai chi receiving a strong recommendation from the American College of Rheumatology. Balance exercises are also conditionally recommended, which makes sense given that joint instability and fall risk increase with osteoarthritis.
The first few weeks of a new exercise routine can temporarily increase joint discomfort. This is normal and typically settles as the muscles around the joint grow stronger and more supportive. Starting at a lower intensity and gradually building up helps manage that transition.
Why Weight Loss Needs to Hit 10%
Losing weight reduces the mechanical load on your knees and hips with every step, but the amount of weight you lose matters more than most people realize. A study tracking people with symptomatic knee osteoarthritis over roughly three years found that losing between 5% and 9.9% of body weight produced essentially no meaningful change in pain or physical function. The threshold for real improvement was 10% or more. At that level, participants reported significantly less pain during daily activities and better ability to move.
This doesn’t mean smaller amounts of weight loss are worthless for overall health, but if your goal is to feel a noticeable difference in your joints, 10% is the target to aim for. For someone weighing 200 pounds, that means losing at least 20 pounds.
Topical vs. Oral Pain Relievers
Anti-inflammatory medications (NSAIDs) are strongly recommended for osteoarthritis in both topical and oral forms. A meta-analysis of eight trials involving over 2,000 patients found that topical and oral NSAIDs provide the same degree of pain relief and the same improvement in stiffness and physical function. The difference is in side effects: gastrointestinal problems like stomach pain, nausea, and ulcers were significantly more common with oral NSAIDs.
For knee osteoarthritis specifically, topical NSAIDs are a strong first choice because the drug is applied directly over the joint and very little reaches the rest of your body. For deeper joints like the hip, topical application is less practical because the joint sits under thick layers of muscle, so oral NSAIDs are more commonly used there.
Acetaminophen (Tylenol) receives only a conditional recommendation. It can take the edge off mild pain but is generally less effective than NSAIDs for osteoarthritis. Capsaicin cream, applied to the skin over the knee, is another conditionally recommended option that works by dulling pain signals from the joint over time.
Injections: What to Expect
Corticosteroid injections into the knee are strongly recommended and can provide meaningful relief, but that relief is typically short-lived. Most of the benefit peaks within the first one to two weeks and fades over the following month. Some studies have shown benefit lasting up to 16 to 24 weeks, but this is less consistent. Injections can be repeated, with some treatment plans spacing them every three months, though repeated use over years remains a topic of ongoing discussion with your provider.
Platelet-rich plasma (PRP) injections have gained popularity in sports medicine clinics, but the evidence does not yet support them for osteoarthritis. The American College of Rheumatology strongly recommends against PRP. Of 11 major international guidelines that addressed PRP, nine were unable to make a recommendation due to insufficient evidence, and two recommended against it. Despite heavy marketing, PRP remains unproven for this condition and is rarely covered by insurance.
Braces, Canes, and Supportive Devices
Using a cane on the opposite side of your affected joint is strongly recommended. It’s simple, effective, and immediately reduces the load your joint has to bear during walking.
For knee osteoarthritis affecting the inner (medial) compartment, which is the most common pattern, valgus unloader braces shift weight away from the damaged side of the joint. During normal walking, the inner compartment of the knee carries about 2.2 times more load than the outer compartment. Unloader braces reduce that excess force by up to 7%, and the majority of studies report meaningful pain improvements compared to simple neoprene sleeves. They work best during activities like walking and standing but can feel bulky and hot, which limits how consistently some people wear them.
For hand osteoarthritis at the base of the thumb, both neoprene (soft) and rigid splints are strongly recommended. They stabilize the joint during gripping and pinching, which are the motions that tend to cause the most pain.
Glucosamine and Chondroitin: The Evidence Is Weak
Glucosamine and chondroitin are among the most commonly purchased supplements for joint health, but their track record in clinical research is disappointing. The American College of Rheumatology, the Arthritis Foundation, and the Osteoarthritis Research Society International all strongly recommend against their use for knee osteoarthritis, citing a lack of meaningful benefit in the best available studies.
A 2018 analysis of 29 studies with over 6,000 participants found that glucosamine or chondroitin taken individually showed some pain reduction, but results were highly inconsistent from study to study. Taking them together showed no significant benefit at all. The American Academy of Orthopaedic Surgeons takes a slightly softer stance, listing glucosamine as potentially helpful for mild-to-moderate knee osteoarthritis while cautioning that the evidence is inconsistent. If you’ve been taking these supplements and feel they help, there’s little harm in continuing, but the data suggests any benefit is modest at best and may not be distinguishable from placebo.
Diet and Inflammation
Osteoarthritis was once thought of as purely a “wear and tear” disease, but low-grade inflammation plays a real role in how quickly it progresses. Higher blood levels of C-reactive protein, a common marker of inflammation, are associated with faster joint deterioration. Excess body fat contributes to this by releasing inflammatory compounds that directly affect joint tissue, independent of the mechanical stress from carrying extra weight.
A Mediterranean-style eating pattern, rich in vegetables, fruits, olive oil, fish, and whole grains, has a low inflammatory profile and may help modulate this process. While no diet can reverse cartilage loss, reducing systemic inflammation through food choices complements the other pillars of management.
Cognitive and Psychological Approaches
Living with chronic joint pain affects mood, sleep, and motivation. Cognitive behavioral therapy is conditionally recommended for osteoarthritis, helping people develop coping strategies that reduce the emotional burden of pain. Self-management programs, which teach you how to set realistic activity goals, pace yourself, and problem-solve flare-ups, carry a strong recommendation. These programs are often available through local Arthritis Foundation chapters or hospital-based wellness centers.
When Joint Replacement Becomes an Option
Joint replacement is considered only after at least three months of non-surgical treatment has failed to provide adequate relief, and imaging confirms advanced joint damage. The decision isn’t based on imaging alone. You need to have significant pain and functional limitation that affect your quality of life, not just an X-ray that looks bad.
Before surgery is approved, providers typically want modifiable risk factors optimized. If your BMI is 30 or above, weight loss is recommended, and a BMI of 40 or higher is generally considered a contraindication. Smokers are asked to quit at least a month before surgery. Blood sugar should be well controlled in people with diabetes. If you’ve had a corticosteroid injection in the affected joint, most surgeons want at least six weeks to pass before operating, as the injection can increase infection risk.
Recovery from hip or knee replacement typically involves several weeks of physical therapy and a gradual return to daily activities. Most people see substantial improvement in pain and mobility within three to six months, with continued gains over the first year.
