To treat a knee sprain, follow the RICE protocol and consider non-operative management, as most acute knee ligament injuries can be treated non-operatively, according to the most recent evidence 1. The RICE protocol involves:
- Resting the knee by avoiding weight-bearing activities for 24-48 hours
- Icing the area for 15-20 minutes every 2-3 hours during the first 48 hours
- Compressing the knee with an elastic bandage wrapped snugly but not too tight
- Elevating the knee above heart level when possible Take over-the-counter pain relievers like ibuprofen (Advil, Motrin) 400-600mg every 6-8 hours or acetaminophen (Tylenol) 500-1000mg every 6 hours as needed for pain and inflammation. After the initial rest period, begin gentle range-of-motion exercises and gradually return to normal activities as pain allows. For moderate to severe sprains, consider using crutches initially to avoid putting weight on the injured knee. Physical therapy may be beneficial for strengthening the muscles around the knee. Seek medical attention if you experience severe pain, inability to bear weight, obvious deformity, or if symptoms don't improve within 1-2 weeks.
Some key points to consider:
- Most acute knee ligament injuries, especially in the absence of other concurrent injuries, can be treated non-operatively 1
- A short period of knee bracing in extension with progression to weightbearing to tolerance is recommended after initial patellar dislocation 1
- Acute traumatic meniscus tears in those younger than 40 can be successfully treated non-operatively and can do equally, as well as those that undergo surgery, at 1 year out from injury 1
- Medial knee ligament injury and instability has frequently been treated by bracing and physical therapy, but there is a subset of patients that remain unstable when treated with conservative measures 2
