Tips for Preventing Knee Pain

If you’re dealing with persistent knee pain, you’re not alone—and it doesn’t always mean you need surgery. Osteoarthritis, the most common form of arthritis, affects more than 32.5 million U.S. adults, according to the CDC, with the knee being one of the most impacted joints. Often associated with aging, osteoarthritis breaks down the cartilage that cushions your joints. The condition can stem from prior injuries, excess weight, or even repetitive stress. Over time, that cartilage deteriorates, leading to pain, swelling, stiffness, and reduced mobility—especially in the knees.

Osteoarthritis in the knee becomes more likely as you age, but pain doesn’t always mean you need a new joint,” said Charles Bush-Joseph, MD, an orthopedic surgeon at Rush University Medical Center in Chicago.

Understanding Osteoarthritis in the Knee

Knee osteoarthritis typically affects adults over 50, though younger individuals with a history of injury or excess weight are also at risk. As the cartilage wears down, bones may begin rubbing together, creating:

• Joint stiffness and tenderness
• Swelling and inflammation
• Cracking or grinding sounds
• Reduced ability to bend or straighten the knee

This joint degeneration can lead to functional decline and increased fall risk—two major contributors to long-term care needs among older adults.

While knee problems become more common when you get older, knee pain can happen at any age. If you’re experiencing persistent discomfort or swelling, exploring professional knee pain treatment options can help prevent long-term complications and improve your quality of life.

There are many treatment options available.

Knee Replacements: A Common but Major Decision

Total knee replacement is one of the most performed surgeries in the U.S., with approximately 1 million procedures done annually, according to the American Academy of Orthopaedic Surgeons (AAOS). That number is projected to rise to 3.5 million by 2030, driven in large part by younger, more active patients under 60.

Surgery is not always necessary.

People with inflammation-related pain often respond well to physical therapy or medication,” said Dr. Bush-Joseph. “Surgery is more often needed for structural damage.

The AAOS reports that over 90% of knee replacement patientsexperience significant pain relief and improved mobility. But surgery isn’t without risk, and it’s not always necessary.

Usually if patient's knees are swollen and they are in pain, I have them ice the knees, stretch and take some anti-inflammatory medications for seven to 10 days. If their knees are still visibly and persistently swollen for longer than that, that warrants further evaluation, including imaging tests like an X-ray or MRI.

Signs You May Need Further Evaluation

Sometimes, your knee pain will resolve with conservative care. But other times, it may signal a deeper issue. Dr. Bush-Joseph recommends the following self-check:

• Try rest, ice, gentle stretching, and NSAIDs (like ibuprofen) for 7–10 days.
• If visible swelling or pain persists beyond 10 days, seek further evaluation.
• Imaging tests such as X-rays or MRIs can help determine whether structural damage is present.

Tips to Help Prevent Knee Problems as You Age

Staying active is key to protecting your knees—especially as you grow older. Rush University Medical Center offers these tips for knee health:

• Maintain a healthy weight to reduce stress on the knee joint
• Build muscle strength, especially in the legs and core
• Use proper technique during exercise and physical activity
• Warm-up and stretch before workouts or prolonged movement
• Wear supportive shoes with good cushioning

Even small changes in daily habits can help reduce your risk of developing or worsening knee osteoarthritis.

Recovery and Long-Term Care Considerations

While knee replacements can be highly successful, recovery often requires intensive physical therapy. Skipping this rehab can lead to poor outcomes, chronic pain, and loss of function—conditions that may trigger the need for long-term care services, either temporarily or permanently. Older adults who delay treatment due to fear of surgery or lack of support may also face increased fall risk, which is a leading cause of injury-related nursing home admissions and ongoing long-term care services.

Medicare only pays for short-term skilled care. To understand how these care needs might affect your financial future, use the LTC News Cost of Care Calculator to see local rates for home health aides, assisted living, and skilled nursing home care. Remember that only Long-Term Care Insurance will pay for extended care services without needing to access Medicaid for those with limited financial resources.

Know Your Options Before Choosing Surgery

You don’t need to rush into the operating room the moment your knee aches. Explore all your options, especially if you’re over 45 and want to stay active without sacrificing your mobility. Talk to your doctor about:

• Physical therapy tailored to your condition
• Anti-inflammatory treatments or injections
• Minimally invasive procedures like arthroscopy
• Lifestyle changes and strength training

Informed decisions now can help you avoid unnecessary surgery—and reduce your long-term care needs later in life.
