Knee Sprains and Strains
The definitions of sprains and strains are similar, and both tend to result in pain and swelling. A sprain is the stretching or tearing of a ligament, which attaches bone to bone; a strain is a tear to the muscle itself. Sprains to the knee ligaments are often caused by sudden or abrupt movements or from contact while playing sports. Strains result from activities that cause the muscles to suddenly stretch or contract; the "pulling" of the hamstring muscle is an example. Be sure to determine what caused the sprain/strain and discontinue that activity - and be seen by a Health Care Professional for a proper diagnosis and treatment.
The R.I.C.E. protocol (rest, ice, compress, elevate) is often recommended immediately after sustaining a mild to moderate sprain or strain, perhaps accompanied by an anti-inflammatory medication such as ibuprofen. But if the sprain or strain is more serious, your Health Care Professional may prescribe immobilizing the knee with a splint or brace.
You can help reduce your risk of injury (or of re-injury) of sprains and strains by committing to an overall physical conditioning program that includes stretching and strengthening and stability exercises for the muscles surrounding the knee. It pays to pace oneself, building up to participating in new activities (or getting back to favorite sports you haven't participated in recently).
This is where the "P" for protection come into the emerging P.R.I.C.E. protocol. Protect your knees while healing from an injury, and for some time afterwards by supporting the injured joint with a brace, wrap, taping or bandaging. And wear proper shoes for your activities, whether you're a runner, walker, or participate in any high impact activity.
