The cruciate ligaments may be injured any time the knee withstands any type of force that separates the bones. Injuries to the cruciate ligament are common in running, jumping, and contact sports. In car accidents, in which the person does not wear a seat belt, ligaments may be injured when knees are thrown into the dashboard. Someone who is out of shape physically or who has had a previous knee injury is more prone to knee injuries. A mild sprain gives mild pain.
Treatment is usually rest and support with an elastic bandage.
Ice and anti-inflammatory medication like aspirin or ibuprofen will assist with swelling and discomfort. These medications should not be taken without approval from your healthcare provider if the person has an ulcer, kidney problems, an allergy to aspirin, or if on a blood-thinning medication. Recovery is slow, but usually complete. A severe sprain or tear of any ligament is a serious injury and may require special bracing or surgery. See your healthcare provider if you have knee pain that does not go away.
