Several approaches reliably reduce knee pain, and the best choice depends on whether your pain is from a recent injury or a longer-term condition like arthritis. Strengthening the muscles around your knee, managing your weight, and using the right over-the-counter medication form the foundation of treatment for most people. Here’s what works, how well it works, and when each option makes sense.
Exercise and Physical Therapy
Strengthening the muscles that support your knee is the single most effective long-term strategy for knee pain. The key muscle groups are your quadriceps (front of the thigh), glutes, and hamstrings. When these muscles are strong, they absorb more of the impact that would otherwise travel through your knee joint. In a clinical trial comparing supervised physical therapy to a home exercise program, patients who worked with a therapist saw a 52% improvement in pain and function within four weeks. Those doing exercises on their own at home still improved by 26% over the same period.
At the one-year mark, both groups had lasting benefits: about 30% improvement from where they started. That’s a meaningful difference in daily life, and it held up without ongoing treatment. The exercises that produced these results were straightforward: leg presses, partial squats, step-ups, and quad-tightening exercises done with the leg straight. Stretching the muscles around the hip, thigh, and calf also played a role.
You don’t need a gym membership to get started. Bodyweight squats, straight-leg raises while lying down, and step-ups on a low stair all target the right muscles. The key is consistency over weeks, not intensity on any single day. If your pain is significant or you’re unsure about form, a few sessions with a physical therapist can set you up with a program tailored to your specific issue.
Weight Management
Your knees bear a multiplied version of your body weight with every step. Being just 10 pounds overweight increases the force on your knee by 30 to 60 pounds per step. That math works in reverse too: losing even a modest amount of weight dramatically reduces the cumulative stress your knees absorb over the course of a day. For someone who takes several thousand steps daily, shaving 10 pounds off the scale translates to tens of thousands of pounds of reduced force on the joint.
This makes weight loss one of the most impactful interventions for people with knee osteoarthritis, especially when combined with the strengthening exercises above.
Over-the-Counter Pain Medication
For day-to-day pain management, you have two main categories at the pharmacy: acetaminophen (Tylenol) and anti-inflammatory options like ibuprofen (Advil, Motrin) or naproxen (Aleve).
Acetaminophen is generally considered the first choice because it carries fewer side effects for most people. It works as a pain reliever but doesn’t reduce inflammation. Anti-inflammatory medications do both, which makes them more effective when swelling is part of the problem. The trade-off is a higher risk of stomach irritation, and with long-term use, potential issues with kidney function and bleeding. These risks increase with age, higher doses, and use beyond three months. If you’re over 60 or have a history of stomach ulcers, anti-inflammatories deserve extra caution.
A topical anti-inflammatory gel applied directly to the knee is another option. It delivers the medication locally without as much of the systemic exposure that causes stomach problems, making it a practical middle ground for people who react poorly to oral anti-inflammatories.
What to Do After a Knee Injury
If your knee pain started with a specific injury (a twist, a fall, a hit during sports), the current best practice has moved beyond the old “RICE” advice of rest, ice, compression, and elevation. Sports medicine experts now recommend a two-phase approach.
In the first one to three days, protect the knee by limiting movement, elevate it above heart level, and use compression with a bandage or sleeve to control swelling. Notably, the updated guidance suggests avoiding anti-inflammatory medications during this early window. Inflammation is part of how your body initiates tissue repair, and suppressing it too early may slow healing.
After those initial days, the focus shifts to gradually loading the knee with movement. Pain-free aerobic activity like walking or cycling increases blood flow to the injured area and supports recovery. The emphasis is on an active approach: returning to normal movement as soon as symptoms allow, rather than resting until the pain is completely gone. Prolonged rest can actually weaken the tissues you’re trying to heal. Your pain level is your guide. If an activity hurts, scale back. If it doesn’t, keep moving.
Your mindset matters here too. Research consistently shows that people who expect to recover well tend to do so, while fear of movement and catastrophic thinking can become genuine barriers to getting better.
Knee Braces and Sleeves
Knee braces fall into two main categories, and picking the right one depends on your situation. Unloader braces are designed for arthritis, particularly when one side of the knee joint is more worn than the other. They redistribute your body weight away from the damaged area to healthier parts of the joint, and they’re the type most commonly recommended by doctors for osteoarthritis.
Functional braces serve a different purpose. They limit how far your knee can move in certain directions, making them the standard choice after a ligament injury or surgery. A basic compression sleeve, which doesn’t fall into either category, can provide mild support and help with swelling but won’t meaningfully offload a damaged joint.
Injections for Persistent Pain
When exercise, weight management, and over-the-counter options aren’t enough, knee injections are a common next step. The two most widely used types are steroid injections and hyaluronic acid injections, and they work on different timelines.
Steroid injections provide faster relief. They outperform hyaluronic acid in the first month, making them useful when you need quick pain reduction. But that advantage fades. By three months, the two types are roughly equal. By six months, hyaluronic acid actually provides better pain control than steroids. So the choice often comes down to whether you need short-term relief right now or longer-lasting benefit. Steroid injections also can’t be repeated indefinitely, as frequent use may accelerate cartilage breakdown over time.
Supplements: Glucosamine and Chondroitin
Glucosamine and chondroitin are among the most popular supplements sold for joint health, but the evidence behind them is weak. A 2022 analysis pooling data from nearly 4,000 people with knee osteoarthritis found no convincing evidence of major benefit. Earlier reviews noted small improvements on pain scales, but the reductions were so modest it wasn’t clear patients could actually feel the difference. One 2016 trial was stopped early because participants taking the supplement reported worse symptoms than those on a placebo pill.
These supplements are generally safe, but if you’ve been taking them for a few months without noticing improvement, the research suggests you’re unlikely to see a meaningful change by continuing.
Signs That Need Urgent Attention
Most knee pain responds to the strategies above, but certain symptoms signal something more serious. Get to urgent care or an emergency room if your knee joint looks visibly deformed or bent out of shape, you heard a popping sound at the time of injury, you can’t put any weight on it, you have intense pain, or the knee swelled up rapidly.
Schedule an appointment soon if your knee is badly swollen, red, warm to the touch, or very painful, especially after an impact. A fever alongside knee pain can indicate an infection in the joint, which requires prompt treatment.
