Sports medicine has helped this field of medicine greatly. In sports, getting a player back in the game is of the utmost importance. There is a vested interest in getting this done in the best way possible.
Many injuries in sports generally happen to the legs and feet of a player, from running and cutting while running. There is always a chance of a player tangling feet with another player or having a player fall on them. From all these different types of injuries doctors have had time to look at different types of treatment. Since the player's main goal is to return to playing form, the doctors need to restore as much natural ability as possible.
A doctor needs to weigh the long term needs of the player. Any medical advancement that hastens healing with as much ability restoration as possible is going to have interest by the sporting community.
