Knee Injuries: Knee Sprain Symptoms and Treatment
(continued)

How long does a knee sprain take to heal?

The average healing times are: (1) mild sprains - 2 to 6 weeks, (2) moderate sprain — 6 to 8 weeks, (3) severe sprains — 8 weeks to 10 months. The complications listed above are more likely to occur in the case of repeated injuries.

What treatment should I use for a knee sprain?

Treatment should consist of following your doctor's instructions. Some supplemental first aids are the "R.I.C.E." instructions: Rest, Ice, Compression, and Elevation (if possible). The doctor usually applies a splint from the ankle to the groin to immobilize the sprained knee. It is helpful, as continuing care, to use an ice pack 3 or 4 times a day for 20 minutes at a time. Place ice chips or cubes in a plastic bag. Wrap the bag in a moist towel, and place it over the injured knee. After the first 72 hours, apply heat instead of ice if it feels better. Use heat lamps, hot soaks, showers, heating pads or heat liniments and ointments. Take whirlpool treatments, if available. Massage gently and often to provide comfort and decrease swelling.

What medications, if any, are recommended?

Medication for minor discomfort can be nonprescription medicines such as aspirin, acetaminophen or ibuprofen. Topical liniments and ointments can be used. Your doctor may prescribe stronger pain relievers or even an injection of a long-acting local anesthetic to reduce pain. General anesthetic for surgery or arthroscopy of the knee joint.
