fractures of any of the bones of the knee are traumatic injuries typically caused by moderate to high forces (such as car accidents contact sports or falls). fractures may be accompanied by swelling or bruising but are almost always extremely painful and tender. the pain is typically so severe that people are often unable to walk or even put their full weight on the knee. fractures are an emergency and should be checked by a doctor. this evaluation will generally include x-rays and other relevant studies. a delay in evaluation can result in fracture fragments being moved and associated injuries. depending on the particular fracture the doctor may either recommend immobilization (with a cast or splint) or surgery to repair it. fractures often heal with no long-term problems. some fractures however are complicated by arthritis or by injuries to arteries or nerves that can be serious.
