The former Watford hit-man has not played for The Railwaymen since picking up the injury towards the end of December.
"He will have a minor operation today (Thursday)," Crewe boss Dario Grado told the club's official website.
Gradi did not comment on how long he expected Smart to be sidelined for, but both player and manager will hope the operation puts an end to the 29-year-old's injury problems.
The Scottish forward has been unfortunate since arriving at Gresty Road from Dundee United in the summer, making just six substitute appearances.
