Knee Injury : Sprain
This represents the most common injury to the knee joint. A sprain refers to a tearing injury to the ligaments which serve to stabilize the knee joint. Knee sprains often occur from a twisting motion to the knee. Any stress, or impact applied to the inside or outside aspect of the knee, can result in a sprain (e.g. clipping injury in football).
Common symptoms of a sprain include the slow onset of pain and swelling over the 24 hours following the injury. This contrasts to a fracture, which causes more immediate symptoms. Severe sprains, with total ligament separation, may be confused with a fracture.Evaluation includes examination to etermine the stability and integrity of the ligaments. Bone x-rays will be taken to rule out the presence of a fracture. In some cases, arthroscopy may be used to directly "look inside" the joint and
determine the extent of ligament damage. An arthrogram can also be performed to better define the extent of a ligament tear. Treatment involves ice compresses, rest, elevation, and crutches to provide nonweight-bearing on the extremity. Splinting in extension allows for proper alignment of ligaments and will accelerate healing. Pain killers may be prescribed in serious cases; however, aspirin or an anti-inflammatory (ibuprofen) will usually suffice. The average knee sprain will take 6 weeks for complete healing with the final 2-3 weeks in a support brace (can often be worn at work).An Orthopaedic Surgeon is recommended for treatment of this injury. Surgery to "rebuild" the ligaments can now be performed through an arthroscope, accelerating healing time. This flexible fiberoptic tube is introduced through a small incision in the skin.
