After knee surgery, natural anti-inflammatories focus on an anti-inflammatory diet rich in omega-3s (fatty fish, walnuts, flax), antioxidants (berries, leafy greens, turmeric), and hydration (water, green tea) to reduce swelling, alongside gentle movement (motion is lotion), ice/heat, and specific supplements like curcumin/bromelain (with doctor approval) to support healing, but always consult your surgeon before starting new supplements.
Nonsteroidal anti-inflammatory drugs (NSAIDs) lessen the swelling that worsens pain. NSAIDs that may be taken after surgery include ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve), celecoxib (Celebrex, Elyxyb) or ketorolac.
Ice and elevation.
To control pain and swelling, apply ice to your knee for 15 to 20 minutes every 2 to 4 hours. When you ice your knee, be sure to raise your knee higher than the level of your heart. Place pillows under your knee for comfort.

They're rich in omega-3 fatty acids, which play a direct role in reducing joint inflammation and stiffness. “These healthy fats have powerful anti-inflammatory properties,” says Wanik. “Try to include fatty fish at least twice a week.
To get rid of inflammation fast, use the RICE method (Rest, Ice, Compression, Elevation) for acute injuries, adopt an anti-inflammatory diet rich in fruits, veggies, and omega-3s while cutting sugar and processed foods, manage stress with relaxation techniques, get quality sleep (7-8 hours), and consider supplements like fish oil or curcumin (turmeric). Gentle movement and staying hydrated with water or green tea also significantly help.
In less invasive surgeries, such as arthroscopy, the swelling usually disappears within a few weeks. However, in more complex operations, swelling may persist for several months after surgery. There may even be extreme cases where six months later there is still excess fluid in the knee.
We found that a moderate amount of vitamin C can significantly treat and reduce the inflammation, as measured by hs-CRP and IL-6, in hypertensive and/or diabetic adults and also helps to reduce FBG levels.
Vitamin C and Zinc
We recommend 500mg of vitamin C daily in both phase 1 and phase 2 of healing. Zinc is a mineral found mostly in animal foods such as meat, fish, poultry, and dairy foods. Zinc is also found in whole grain breads and cereals, legumes (dried beans and peas), and nuts.
Here's what some small studies found:
Depending on the cause, it can go away on its own. However, if it does not go away after a few days, you may need treatment and should see your GP. What is the best anti-inflammatory for knee pain? Knee pain can be effectively reduced by taking non-steroidal anti-inflammatories (NSAIDs) such as ibuprofen.
Orange, tomato, pineapple and carrot juices are all high in the antioxidant, vitamin C, which can neutralize free radicals that lead to inflammation.
If you've recently had surgery, here are some techniques your doctor may recommend to help reduce swelling and manage edema after surgery.
Your body and your knee joint will continue to gain strength for several months after your surgery. There shouldn't be any pain after the first four months. If you continue to feel pain, be sure to talk to your surgeon.
Studies have found that berries rich in antioxidant polyphenols, like blueberries, strawberries, raspberries, and pomegranate, reduce inflammation and painful joint swelling. Eating to reduce pain sounds delicious!
While there's no single "strongest," Omega-3 fatty acids (from fatty fish) and curcumin (from turmeric) are consistently cited as highly potent natural anti-inflammatories, alongside powerful antioxidants from fruits and vegetables like blueberries, plus herbs like ginger and garlic, all working to reduce inflammation pathways. A comprehensive anti-inflammatory diet emphasizes these foods, though Omega-3s and curcumin often stand out for their significant impact.
The diabetic omnivores with higher levels of vitamin B-12 had significantly lower oxidative stress (MDA, p = 0.06) and inflammation (IL-6, p = 0.04) than those with lower levels of vitamin B-12 and the vegetarians (MDA, p = 0.01; hs-CRP, p = 0.03; IL-6, p = 0.02).
Bananas contain anti-inflammatory components that could have a significant impact on human health. One such component is bromelain, an enzyme known for its anti-inflammatory properties [5]. Bromelain has been studied for its potential to reduce inflammation and alleviate symptoms in conditions such as osteoarthritis.
10 Effective Ways to Manage Swelling After Knee and Hip Replacement Surgery
It's normal to feel stiffness right after surgery, which usually lasts for 2 weeks to 3 months as your knee adjusts to the implant. Most improvement in movement happens within the first 6-12 weeks, with further progress continuing for up to 6-9 months.
Following an exercise regime can also reduce swelling, increase your range of motion and strengthen your body.

As of 2025, PRP has moved beyond being an experimental therapy. It is now recognized as one of the leading biologic options for knee osteoarthritis. Ongoing studies are exploring how PRP can be combined with stem cell therapy or other regenerative techniques to further enhance outcomes.
A Chinese herbal preparation, SiMiaoFang (SMF), has been used clinically for treating arthralgia by virtue of its anti-inflammatory and pain-relieving activities. However, no evidence base links SMF to anti-osteoarthritis (OA), particularly its link to inhibiting cartilage matrix degradation.
XELJANZ is a Janus kinase (JAK) inhibitor that helps regulate an overactive immune system. It helps disrupt JAK pathways from inside the cells, which are believed to play a role in inflammation. XELJANZ helps reduce inflammation, a cause of permanent joint damage.
