For knee pain, your best options depend on whether the pain is from a recent injury or an ongoing problem like arthritis. Most people get meaningful relief from a combination of approaches: over-the-counter pain relievers, targeted exercises, weight management, and supportive devices. Here’s a breakdown of what works and when to use each option.
Immediate Relief for a New Injury
If your knee pain started after a twist, fall, or impact, start with the POLICE protocol: Protection, Optimal Loading, Ice, Compression, and Elevation. Apply ice or a cold pack for 15 to 20 minutes every one to two hours during the first 48 hours. Place a cloth between the ice and your skin to prevent frostbite. Ice constricts blood vessels, limits swelling, and numbs pain quickly.
“Protection” means avoiding movements that make the pain worse, while “optimal loading” means gently moving the joint within a pain-free range rather than immobilizing it completely. Wrapping the knee with a compression bandage and elevating it above heart level when resting both help control swelling in those first couple of days.
Over-the-Counter Pain Relievers
Acetaminophen (Tylenol) works well for mild knee pain and is gentle on the stomach. To stay safe, aim for no more than 3,000 milligrams per day, even though some labels list 4,000 milligrams as the maximum. Higher doses can cause liver problems, and you should avoid acetaminophen entirely if you drink alcohol regularly or have liver disease.
NSAIDs like ibuprofen (Advil, Motrin) and naproxen (Aleve) are often more effective for knee pain because they reduce inflammation in addition to blocking pain signals. This matters because most knee pain involves at least some inflammation, whether from arthritis, a strain, or overuse. The trade-off is that NSAIDs can irritate the stomach, and long-term use at high doses raises the risk of ulcers, heart problems, and kidney issues. For short-term flare-ups, though, they’re typically the better choice.
Topical Treatments
If you want to avoid swallowing pills, topical anti-inflammatory gels are a solid alternative. Diclofenac gel (available over the counter as Voltaren) is applied directly to the knee four times a day. Because the medication absorbs through the skin right at the joint, it delivers less of the drug to your bloodstream, which means fewer stomach and cardiovascular side effects than oral NSAIDs. For knee osteoarthritis specifically, topical NSAIDs are a first-line recommendation in most clinical guidelines.
Menthol-based creams and capsaicin patches can also provide temporary relief by creating a cooling or warming sensation that overrides pain signals. They won’t address the underlying problem, but they can take the edge off during daily activities.
Exercises That Reduce Knee Pain
Strengthening the muscles around your knee is one of the most effective long-term strategies for reducing pain. Weak quadriceps (the muscles on the front of your thigh) are a major contributor to knee problems because they can’t adequately stabilize the joint. The American Academy of Orthopaedic Surgeons recommends a structured conditioning program lasting four to six weeks to see meaningful improvement.
A well-rounded knee program includes:
- Straight-leg raises: 3 sets of 10, four to five days per week. These build quad strength without bending the knee.
- Half squats: 3 sets of 10, four to five days per week. These strengthen the quads and glutes through a controlled range of motion.
- Hamstring curls: 3 sets of 10, four to five days per week. Balancing the muscles behind your knee with those in front protects the joint.
- Calf raises: 2 sets of 10, six to seven days per week. Strong calves support the entire lower leg chain.
- Hip abduction and adduction: 3 sets of 20, four to five days per week. Weak hips allow the knee to collapse inward during walking, increasing stress on the joint.
Stretching matters too. Heel cord stretches, standing quad stretches, and hamstring stretches done regularly help maintain range of motion and prevent the tightness that pulls on the knee from above and below. The key is consistency over weeks, not intensity on any single day. Start gently and increase resistance as the exercises become easier.
Weight Management
Carrying extra weight puts enormous pressure on your knees. Being just 10 pounds overweight increases the force on the knee by 30 to 60 pounds with every step. That adds up to hundreds of thousands of extra pounds of force per day during normal walking.
Clinical guidelines recommend that people with knee osteoarthritis who are living with excess weight aim for a 5 to 10 percent weight loss over a 20-week period. That level of reduction is consistently associated with less pain and better quality of life. For a 200-pound person, that’s 10 to 20 pounds, a realistic goal that can produce a noticeable difference in how your knees feel during stairs, walking, and standing.
Knee Braces and Sleeves
Not all knee supports do the same thing. Compression sleeves are made of snug elastic material that provides light pressure around the joint. They don’t offer structural support, but they improve your awareness of the joint’s position (called proprioception), which can reduce pain during activity and help prevent awkward movements.
Unloader braces are a step up. They’re specifically designed for arthritis and work by shifting your body weight away from the damaged part of the knee to healthier areas of the joint. They’re the most commonly recommended type of brace for knee arthritis. A walking stick or cane, used on the opposite side from the painful knee, can also reduce joint stress during flare-ups.
Supplements
Glucosamine and chondroitin are the most popular joint supplements, but the evidence is more nuanced than the marketing suggests. A 2024 meta-analysis of 30 clinical trials covering over 5,200 patients found that glucosamine combined with chondroitin alone does not produce clinically significant pain relief in people with mild-to-moderate knee osteoarthritis.
What did show a large pain-reducing effect was glucosamine paired with omega-3 fatty acids. This combination was the most effective for both short-term and long-term pain, and it also had the lowest rate of side effects among all the treatments studied. Glucosamine combined with MSM (methylsulfonylmethane) also showed a large effect, though the results were less consistent. If you want to try supplements, the evidence favors adding an omega-3 fish oil alongside glucosamine rather than the traditional glucosamine-chondroitin pairing.
Injections for Persistent Pain
When oral medications and exercise aren’t enough, joint injections are the next tier of treatment. The three main types work on different timelines.
Corticosteroid injections deliver a powerful anti-inflammatory directly into the knee joint. The steroid kicks in two to three days after the injection. Most people get a few weeks to a few months of relief, though some get many months and others don’t respond at all. These are best used for acute flare-ups rather than as a recurring treatment, since repeated steroid injections can weaken cartilage over time.
Hyaluronic acid injections work by supplementing the natural lubricant in your knee joint. They take several weeks to produce improvement, so they require patience. But the payoff can last months or longer, making them a better option for people looking for sustained relief rather than a quick fix.
Platelet-rich plasma (PRP) injections use a concentrated sample of your own blood to promote healing in the joint. Most people notice improved function and less pain within two to six weeks. PRP is typically not covered by insurance and costs several hundred dollars per injection.
Warning Signs That Need Medical Attention
Get to urgent care or an emergency room if your knee is visibly deformed, you heard a popping sound at the time of injury, you can’t bear weight on it, you have intense pain, or the knee swelled up suddenly. These can signal torn ligaments, fractures, or dislocations that need immediate evaluation.
Schedule an appointment with your doctor if your knee is badly swollen, red, warm and tender, or very painful after an injury. Warmth and redness together can indicate infection inside the joint, which is a serious condition. Also call if you have a fever alongside knee pain, or if ongoing knee pain is interfering with sleep or daily activities.
