An improved one piece tibial tray uniquely characterized by its construction including an asymmetric keel extending from the bottom of the tibial tray base plate, whereby insertion of the tray during arthroplasty may be accomplished with a smaller than normal incision, enhancing the efficacy and safety of the surgical procedure. A fin on either or both sides of the asymmetric fin may be provided for enhanced stability of the tray.
