Modular surgical instrumentation and a method of using same is provided, according to the invention. The instrumentation comprises a first bracket (10) defining a generally U-shaped structure having an internal surface adapted to be seated on the distal aspect of a resected femur (11) bone and an elongated central opening (23) appointed to expose a selected area of the resected femur, including a curved track (20,21) for guiding a first shaping tool (30) along a predetermined path for controlled shaping of a curved patellar groove in a portion of the selected ares exposed through the opening. A second bracket (300) defines a linear slotted bore (302) extending generally parallel to the long axis of the femur for guiding a second shaping tool (304) to form a relatively deep recess accommodating an intercondylar stabilizing housing of a knee implant. The second bracket has an internal surface defining a shape adapted for releasable engagement with the curved track, including mechanism for accurately aligning the slotted bore relative to the opening while forming the recess. <IMAGE>
