To treat a knee sprain, start with the RICE protocol: Rest the knee to prevent further injury, apply Ice for 15-20 minutes every 2-3 hours for the first 48-72 hours, use Compression with an elastic bandage wrapped snugly but not too tight, and Elevate the knee above heart level when possible. The RICE protocol is a widely accepted treatment for knee sprains, as it helps reduce pain, swelling, and inflammation, promoting healing and preventing further injury 1, 2, 3. For pain management, take over-the-counter medications like ibuprofen (Advil, Motrin) 400-600mg every 6-8 hours or acetaminophen (Tylenol) 500-1000mg every 6 hours as needed. Some key points to consider when treating a knee sprain include:
- Avoid activities that cause pain for at least 1-2 weeks, but gentle movement within pain limits helps prevent stiffness.
- As pain decreases, begin gentle strengthening exercises like straight leg raises and hamstring curls.
- Most mild to moderate knee sprains improve within 2-6 weeks with proper care.
- Severe sprains may require physical therapy or, rarely, surgical intervention.
- Seek medical attention if you experience severe pain, inability to bear weight, obvious deformity, or if symptoms don't improve within a week. Additionally, some studies suggest that low-level laser therapy (LLLT) can be used in conjunction with the RICE protocol to reduce edema in second-degree ankle sprains, which may also be applicable to knee sprains 4. However, it's essential to prioritize the RICE protocol and gentle exercises, as these are the most widely accepted and effective treatments for knee sprains, with the goal of minimizing morbidity, mortality, and improving quality of life.
