If you're trying to understand your options for osteoarthritis, including after several treatments haven't helped enough, you're in the right place.
Osteoarthritis: where each option sits in the evidence
Most osteoarthritis care focuses on pain, movement, and function. There isn't an approved drug shown to change the disease itself the way some rheumatoid arthritis medicines can. This map shows where each option fits, what it can realistically do, and where the evidence becomes less certain.
Use this map to understand the options and prepare better questions for your clinician. It isn't a guide to starting, stopping, or changing treatment on your own.
The evidence landscape
See the different roles these options play. Not a menu. A landscape.
- Where most care starts Exercise | Weight management (when relevant) | Creams and pills
- Short-term steroid injections Corticosteroid injections
- Contested injections Hyaluronic acid | PRP
- Supplements Glucosamine and chondroitin | Curcumin
- Investigated, not established Stem cells | Possible disease-modifying drugs
- Surgery Arthroscopy | Joint replacement
Treatments that change the underlying disease, not just the pain, are called disease-modifying treatments. Osteoarthritis does not currently have an approved option in that class. Rheumatoid arthritis is a separate map.

These are common decisions people face with osteoarthritis. The evidence isn't equally strong for every option, and knee, hip, and hand don't always share the same evidence. The answers make those differences clear when they matter.
Where most care starts
Exercise, weight management when it's relevant, and creams or pills.
- Does exercise help? Is the hip the same as the knee? Guidelines strongly recommend it. Average pain change is modest, and the hip evidence is thinner than the knee evidence.
- When can weight loss help? For people with overweight or obesity, knee pain may ease with meaningful weight loss. That doesn't automatically transfer to hip pain.
- Creams or pills? Topical anti-inflammatory creams are often used first for knee and hand OA. Oral anti-inflammatories can help too, but bring more stomach and cardiovascular risk. Opioids generally don't provide enough benefit to justify their harms for routine OA care.
Short-term steroid injections
Can ease pain for a while. Not disease control.
Contested injections
Two different shots. They don't share one story.
- Do gel shots work? Large trials find them about the same as placebo for pain. Guidelines disagree. This is not a rebuild.
- What about PRP? Is it the same as a gel shot? A different injection. Some placebo-controlled trials show meaningful improvements in pain and function, but guidelines still disagree. It isn't evidence of regeneration.
Supplements
Widely marketed. Different evidence behind the bottles.
- Does glucosamine rebuild cartilage? Independent data show no benefit from glucosamine over placebo for hip or knee OA. Chondroitin has separate evidence, including a conditional recommendation for hand OA in one guideline.
- What about turmeric? Some short-term studies suggest knee-pain relief, but the evidence is mixed and it isn't part of core osteoarthritis care.
Investigated, not established
Popular questions. Not established care.
- Do stem cells regenerate the joint? They may slightly improve pain and function, but the evidence is low certainty. Regeneration is not established. This is not PRP.
- Is there a drug that changes osteoarthritis itself? Not an approved one. Pain and function options still matter. Rheumatoid arthritis medicines are a different map.
Surgery
Two very different decisions. Arthroscopy usually doesn't help degenerative knee disease. Joint replacement is a later option for people who are already surgical candidates.
- Is arthroscopy worth it? For degenerative knee disease, arthroscopy offers little or no meaningful benefit over a placebo procedure. Not the same decision as joint replacement.
- When is joint replacement the question? For people already candidates for surgery. Knee and hip have separate evidence. It doesn't mean exercise was a waste.
