You can initially treat non-traumatic knee swelling at home. Don’t play sports or do any activity that can put more stress on your knee. Over-the-counter pain medications like NSAIDs or acetaminophen can relieve pain and reduce inflammation. Talk to a healthcare provider before taking pain relievers for more than 10 days in a row.

Follow the RICE method as soon as you notice pain or other symptoms:

• Rest: Avoid the activity that caused your injury. Don’t overuse your knee while it heals.
• Ice: Apply a cold compress or ice packs wrapped in a thin towel to your knee for 15 minutes at a time, a few times a day.
• Compression: You can wrap your knee in an elastic bandage to help reduce swelling.
• Elevation: Prop your knee and leg up above the level of your heart as often as you can.

A healthcare provider might suggest other treatments if you have a specific injury or health condition. You might need:

• Crutches.
• A brace that holds your knee in place.
• Physical therapy.
• Corticosteroids.
• Surgery for knee swelling

How can you prevent knee swelling?

During sports or other physical activities:

• Wear the proper protective equipment.
• Don’t “play through the pain” if your knee hurts during or after physical activity.
• Give your body time to rest and recover after intense activity.
• Stretch and warm up before playing sports or working out.
• Cool down and stretch after physical activity.

Follow these general safety tips to reduce your risk of an injury:

• Make sure your home and workspace are free from clutter that could trip you or others.
• Always use the proper tools or equipment at home to reach things. Never stand on chairs, tables or countertops.
• Use your cane or walker if you have difficulty walking or have an increased risk of falls
