There are multiple ways to break a leg on purpose, although many of these ways could result in injury to other areas of the body. Having someone assist in hitting the leg with an object could work; however, this action is illegal and should never be performed.
After breaking a bone, an orthopedic surgeon will most likely be able to tell how the leg was broken, due to the type of bruising and how clean the break is. Breaking a leg on purpose can lead to lifetime pain, medical bills not covered by insurance, medical complications or criminal charges for the person who assists in committing the injury.
