Knee Contusion After Injury: Post-Trauma Bruise Care Tips
Summary
A knee contusion is a common injury that occurs when your knee gets hit directly, causing bruising and swelling without any major structural damage. You might notice pain and difficulty moving the joint. This handout provides simple steps you can take at home to help your knee heal faster and feel better. Remember, if your symptoms get worse, it's important to contact your doctor.
What Is This & Why It Matters
A knee contusion is essentially a bruise on your knee. It happens when you bump or hit your knee hard enough to damage the small blood vessels under the skin, leading to discoloration and swelling. While it might look alarming, it's usually not serious. The goal of treatment is to reduce pain and swelling so you can get back to normal activities as soon as possible.
What You Should Do
- Rest your knee as much as possible. Avoid putting too much weight on it.
- Apply ice packs for 20 minutes every hour. Do this for the first 48-72 hours.
- Keep your leg elevated above heart level when sitting or lying down.
- Use a compression bandage to wrap your knee snugly but not too tight.
- Take over-the-counter pain relievers like ibuprofen with food, as needed.
- Follow the RICE protocol: Rest, Ice, Compression, Elevation.
- Wear comfortable shoes that provide good support while recovering.
- Schedule a follow-up appointment in 3-5 days to assess recovery.
What You Should NOT Do
- Don't keep the ice on your knee for more than 20 minutes at a time.
- Avoid applying heat in the first 72 hours post-injury.
- Do not engage in strenuous activities that may strain the knee further.
- Refrain from massaging the bruised area too hard.
- Don't ignore worsening symptoms or severe pain.
Symptoms: Normal vs Warning Signs
