A sprain occurs when the threads or fibers of the ligaments are stretched or torn. This injury can be classified as a grade I, grade II, or grade III sprain. Grade I sprains occur when the fibers are stretched but not fully torn, little tenderness and swelling, and the knee does not feel unstable or give out during an activity. Grade II Sprains occur when the fibers of the ligament are partially torn, little tenderness and moderate swelling, and the joint may give out during an activity. Grade III sprains occur when the fibers of the ligament are completely torn, and the ligament itself has torn completely into two
