Rest the knee and avoid activities that worsen pain or swelling
Apply ice for 15–20 minutes every 2–3 hours
Wrap the knee with a compression bandage, not too tight
Elevate the leg above heart level when resting
Take an over-the-counter anti-inflammatory pain reliever if safe for you
Avoid heat, alcohol, and heavy exercise until swelling improves
Use crutches or reduce weight-bearing if walking increases pain
Gently move the knee through pain-free range to prevent stiffness
Seek urgent medical care if swelling is severe, sudden, after injury, or with fever, redness, warmth, or inability to bear weight
