Knee fracture is a break or failure of one of the bones that make up the joint (femur, tibia, fibula and patella). Usually, these bones are injured by falls, traffic accidents, injuries in contact sports and exercise, shock and other injuries. Symptoms of knee fracture are pain, swelling, limited range of motion, deformed leg and inability to walk, among others. Treating knee fracture depends on fractured bone and the type of fracture. If parts of the bones are properly aligned, perhaps it is enough to placing a splint or cast to the knee. However, if the patella is affected, you could specify an operation. Therefore, the recovery of the injury depends on the fractured bone, fracture type, treatment and evolution.
