If you are asking what the best treatment for knee osteoarthritis is, the honest answer is that no single option works best for everyone. Knee osteoarthritis (OA) is a long-term condition, and there are many ways to ease its symptoms, from exercise and physical therapy to pain medicines, injections and, when daily life is badly affected, surgery. The right mix depends on your knee, your health and what you want to be able to do, and it is a choice to make with your clinician.
Most people reach this question after a headline or video about a new knee treatment. Below, each option is sorted into what doctors commonly offer now, what is still being studied, and what you can do at home, so you can see where each one fits.
Does knee arthritis ever go away?
No. Cleveland Clinic’s knee osteoarthritis guide describes it as a lifelong, progressive condition, but treatment can help manage your symptoms. Cartilage is the cushion between the bones, and once it breaks down it does not grow back. The NIAMS osteoarthritis overview from the National Institute of Arthritis and Musculoskeletal and Skin Diseases says joint damage “usually develops gradually over years, although it could worsen quickly in some people.” As of November 2026, that is the picture from both sources: the goal is to manage symptoms and slow progress.
How can you stop knee osteoarthritis from getting worse?
You usually cannot stop it completely, but you can slow it and keep your symptoms under control. Cleveland Clinic says there is usually no single cause, so it cannot be fully prevented, but you can reduce the stress and strain on your knee. It also says that if you carry extra weight, losing just 10% of it can significantly reduce your risk of knee OA. Hospital for Special Surgery (HSS) says that “any form of exercise that helps you maintain a healthy weight can reduce the stress on your joints, and this may slow the progression of your arthritis.” Starting care early also helps. Cleveland Clinic says early treatment offers the best chance of slowing osteoarthritis and managing symptoms without surgery.
What should you avoid doing?
Avoid letting inactivity take over. NIAMS explains that if joint pain makes you less active, “this can lead to muscle weakness, which may cause more stress on the joint.” Walking and gentle strength work are the usual ways to break that cycle. HSS says walking “can help decrease the pain and stiffness associated with osteoarthritis.” You can read more in our guide to is walking good for knee pain and in our guide on how to improve knee strength.
Other practical points from Cleveland Clinic:
- If you jog or run, look for soft surfaces rather than pavement.
- Vary your fitness routine with low-impact exercise such as swimming or cycling.
- If your job puts strain on your knees, consider changing how you do the work.
- Do not wait on new knee pain that seems to come for no apparent reason and keeps getting worse. Talk to your provider.
- Be careful with supplements. The National Center for Complementary and Integrative Health (NCCIH) says “Some dietary supplements may have side effects and may interact with medications.”
What is the best treatment for knee osteoarthritis?
Cleveland Clinic says that “healthcare providers try nonsurgical treatments first before recommending surgery for knee OA.” Its guide lists nonsurgical options as pain medicines, physical therapy, sometimes weight loss, a knee brace, cortisone injections, knee gel shots (viscosupplementation), genicular nerve block injections, platelet-rich plasma injections and genicular artery embolization. The table below compares the options.
| Option | What the sources say | Who it may suit | Limits to weigh |
|---|---|---|---|
| Physical therapy | HSS says “Physical therapy should always be a part of the treatment for knee osteoarthritis.” Rush’s physiatrist Rachel Welbel, MD, often recommends six to eight weeks of physical therapy for knee OA. | People who want to strengthen the muscles that support the knee | Rush says shoulder and hip OA respond less well to physical therapy than knee OA does. |
| Tai chi | NCCIH reports that the American College of Rheumatology and Arthritis Foundation guideline strongly recommends tai chi for knee or hip OA. Studies found improvements in pain, stiffness, balance and physical function. | People who want low-impact, movement-based options | Like other exercise, it can cause sore muscles and carries some risk of injury. |
| Yoga | NCCIH reports that the same guideline conditionally recommends yoga for knee OA, based partly on its similarity to tai chi. A limited amount of research suggests it may help pain, function and stiffness. | People who prefer a gentle routine | The research is more limited than for tai chi. |
| Acupuncture | NCCIH says acupuncture may be helpful for knee pain associated with osteoarthritis. The guideline conditionally recommends it, and NCCIH notes that the evidence is controversial. | People interested in a non-drug option for knee pain | Less evidence exists for hip osteoarthritis. |
| Topical or oral NSAIDs | Rush says topical lidocaine or a diclofenac product is a reasonable starting point. It also says “topical and oral nonsteroidal anti-inflammatory drugs provide similar pain relief,” and topicals have fewer side effects. | People who want pain relief at home | Oral NSAIDs can cause cardiovascular and gastrointestinal problems, according to the Arthritis Foundation. |
| Corticosteroid injections | Rush says steroid injections “can reduce stiffness and pain” at painful joint sites. | People whose symptoms have not improved with therapy and medicines | Rush lists infection and bleeding as risks, and says over-reliance can damage joints over the long term. |
| Hyaluronic acid injections | Rush says these may be an option if steroid injections no longer help. The Arthritis Foundation reports that in a ranking study, they were no better than placebo for pain and function. | People with knee or shoulder arthritis after other options | Guidelines differ. Some recommend them, others are neutral, and some recommend against them. |
| Low-dose radiation therapy | Rush describes it as an option when medicines or physical therapy have not been enough. | People who have tried medicines or therapy | Ask your clinician whether it is offered where you live. Cleveland Clinic’s list of nonsurgical options does not include it. |
| Knee brace | Cleveland Clinic lists a knee brace among nonsurgical treatments for knee OA. | The Cleveland Clinic guide does not describe who a brace suits. Ask your clinician whether one fits your knee. | The Cleveland Clinic guide does not describe how well a brace works. |
| Surgery | Cleveland Clinic says surgery is an option “when it starts to really impact your life.” | People whose daily life is badly affected despite other care | Covered in its own section below. |
Which knee pain medicines have the best evidence?
The Arthritis Foundation reports on a study that ranked non-surgical drug treatments for knee OA against each other on pain relief and physical function. Its main finding: naproxen “works best for both pain and function,” and it is one of the least expensive NSAIDs. Acetaminophen ranked near the bottom. Hyaluronic acid injection was no better than placebo.
The study has limits. It ranked treatments against each other rather than showing how well each one works alone. It did not cover side effects in detail, and it left out exercise and weight loss. Stuart Silverman, MD, a clinical professor at Cedars-Sinai and UCLA, quoted in the same report, said: “I would not use this study as a road map for treating patients.” Rush also notes that over-the-counter options include naproxen and ibuprofen, while prescription options include celecoxib and meloxicam. Your clinician can choose among them based on your other health conditions and the medicines you already take.
Are knee injections worth it?
Injections are one of the more debated options, and the research and guidelines do not agree on how much they help. Rush’s clinician says a steroid injection often comes after six to eight weeks of physical therapy, and that injections “do have some risks, including infection and bleeding.” Cleveland Clinic lists several injection options, including knee gel shots, platelet-rich plasma and genicular nerve block injections, without describing how well each works. The Arthritis Foundation’s ranking study found hyaluronic acid no better than placebo for pain and function. Some guidelines recommend it and others do not, so ask your clinician which injection, if any, fits your knee and what the risks are for you.
What about low-dose radiation therapy for the knee?
Rush describes low-dose radiation therapy (LDRT) as an older treatment that fell out of use and is now being looked at again. Paul Kreinbrink, MD, a radiation oncologist who performs LDRT at Rush, says that “research shows that 60% to 80% of osteoarthritis patients who have LDRT experience at least some relief, which can last for up to a year or more.” Treatment involves six 15-minute appointments over two to three weeks. Rush says afterward you have no restrictions and most people feel less joint pain within a few weeks. It may be an option if you have already tried medication or physical therapy. Ask your radiation oncologist about the research and whether your plan covers it.
Are exercise, tai chi and yoga enough on their own?
For many people, movement is the core of care. Physical therapy is treated as the foundation. HSS says the best exercise is the one that suits your lifestyle and that you can keep doing. A physical therapist can help you pick the type and amount that is safe for you. NCCIH’s summary of the 2019 guideline also notes that tai chi is strongly recommended for knee or hip OA. If you are starting a strengthening routine, our guide on how to improve knee strength walks through the basics and safety points.
Are glucosamine, chondroitin and other supplements worth taking?
NCCIH’s summary of glucosamine and chondroitin for osteoarthritis says it is “still uncertain whether glucosamine and chondroitin are helpful for knee osteoarthritis symptoms.” Major guidelines disagree. As of November 2026, the table below shows what each guideline or study says for each supplement.
| Supplement | What the guidelines and studies say | Side effects and cautions |
|---|---|---|
| Glucosamine | The 2019 American College of Rheumatology and Arthritis Foundation guideline strongly recommends against glucosamine for knee OA. The 2019 OARSI guideline also strongly recommends against it. The 2021 American Academy of Orthopaedic Surgeons guideline lists it among supplements that may help mild-to-moderate knee OA, while noting the evidence is inconsistent. | NCCIH says glucosamine may raise blood sugar in some people. Glucosamine and chondroitin have been associated with increased bleeding risk in people taking warfarin. |
| Chondroitin | The 2019 American College of Rheumatology and Arthritis Foundation guideline strongly recommends against chondroitin for knee OA. The 2019 OARSI guideline also recommends against it, citing low-quality evidence. The 2021 AAOS guideline lists it as possibly helpful, with inconsistent evidence. | Same bleeding caution with warfarin as for glucosamine. |
| Fish oil | The guideline conditionally recommends against fish oil for osteoarthritis, because only one study exists and it did not show that a higher dose works better than a lower one. | |
| Vitamin D | The guideline conditionally recommends against vitamin D for osteoarthritis because the overall evidence does not show a benefit. | The NIH Office of Dietary Supplements warns that thiazide diuretics “could raise your blood calcium level too high if you take vitamin D supplements.” |
| DMSO and MSM | NCCIH says there is not enough research on these for osteoarthritis pain to allow conclusions. | |
| SAMe | NCCIH says the evidence on SAMe for knee or hip osteoarthritis is inconclusive. |
NCCIH also reports that the U.S. Food and Drug Administration “has warned the public about several dietary supplements promoted for arthritis or pain that were tainted with prescription drugs.” The NIH Office of Dietary Supplements advises that you “Tell your doctor, pharmacist, and other health care providers about any dietary supplements and prescription or over-the-counter medicines you take.”
What new knee treatments are still being studied?
Headlines about knee treatments often mix three things: care doctors offer now, drugs being tested in people, and lab work. Duke Health’s April 6, 2026 news release is an example of the lab-work stage. It describes three experimental treatments designed to activate the body’s repair processes in cartilage and bone. In animal models, the experimental drug treatments restored joint tissue to near-normal levels. Duke says, “Although the therapies have not yet been tested in humans, the results point to a promising new way to address osteoarthritis.”
The team expects to be ready for first-in-human trials within 18 to 24 months, if progress continues as planned. First they must complete advanced safety testing, dosing studies and preparation for a new drug application with the U.S. Food and Drug Administration. As of November 2026, these are research-stage ideas, not treatments you can get.
When is surgery considered for the knee?
Cleveland Clinic says that when osteoarthritis “really impacts your life,” surgery is an option. Its guide lists cartilage replacement, knee bone reshaping (osteotomy), partial knee replacement and total knee replacement. HSS says an osteotomy may suit people with early-onset arthritis partly caused by alignment problems, such as knock knees or bowlegs. The Arthritis Foundation reports that total knee replacement is effective but is done only when the disease is advanced and medically necessary. Duke Health says knee OA is the leading cause of total knee replacement surgery, with nearly 800,000 procedures performed each year in the United States.
Can you treat knee osteoarthritis at home?
Several of the options above are routines you can carry out at home with guidance. Four steps come up most often: keep moving with low-impact exercise and walking, keep a healthy weight, choose softer surfaces for running or jogging, and ask about topical pain relief. Rush notes that topical products are often a starting point and are safer for people with heart or digestive conditions. A physical therapist can show you how to do the routine safely and how to progress it over time.
Is osteoarthritis a disability?
Cleveland Clinic says knee OA “can eventually lead to disability.” The NIAMS osteoarthritis overview says that for some people, osteoarthritis “is relatively mild and does not affect day-to-day activities,” while for others “it causes significant pain and disability.” Ask the agency or insurer that handles your claim what documentation it needs. Ask your clinician to note in your chart how knee pain limits your walking, standing, stairs and work.
Does diet matter for knee osteoarthritis?
Rush’s Dr. Welbel recommends “an anti-inflammatory diet — high in whole foods, low in processed foods,” and says that maintaining a healthy weight can reduce the pressure on your knees and lessen pain in that joint. For specific foods such as bananas or ice cream, ask a registered dietitian to review your overall eating pattern.
What should you ask at your next visit?
Bring a clear picture of your symptoms. Track how long morning stiffness lasts (NIAMS describes typical stiffness as lasting less than 30 minutes), whether the knee swells after activity, and whether it ever feels like it will give way. Bring a full list of your medicines and supplements, using your medication list for a pain-care visit.
Questions worth asking:
- Is this osteoarthritis, or could it be another kind of arthritis? HSS notes that inflammatory arthritis joints are often much redder and more swollen.
- Which option would you start with for my knee, and why?
- How long should I try physical therapy before we reassess?
- Which pain medicines fit my heart, stomach and other health conditions?
- What does each option cost with my plan?
- If an injection is on the table, what are the infection and bleeding risks for me?
- What would make you suggest surgery for my knee?
- Do any of my supplements interact with my medicines?
If your knee pain has changed suddenly, or is getting worse without a clear reason, bring that up at the start of the visit. Cleveland Clinic advises talking to your provider in that situation, because early treatment offers the best chance of slowing osteoarthritis.
Prices for these options vary by plan, pharmacy and region, so ask your insurer and clinic for the cost of each one before you start. The Arthritis Foundation reports that naproxen is one of the least expensive NSAIDs. The ChoosePT physical therapy guide says a new study found physical therapy for knee OA outperforms steroid injections and is cost-effective.
