(54)	Orthopaedic bolt tightening method

(57) A method of assembling an orthopaedic implant includes positioning a first orthopaedic component in contact with a second orthopaedic component and coupling the first orthopaedic component to the second orthopaedic component with a bolt. The method also includes applying an empirically-determined starting torque to the bolt such that the first orthopaedic component is coupled to the second orthopaedic component with a first predetermined clamp load. The bolt is then rotated by an empirically-determined rotation angle such that the first orthopaedic component is coupled to the second orthopaedic component with a second predetermined clamp load.
