Abstract:
1. An orthopedic surgical system for resection of a distal end of a femur and a proximal end of an adjacent tibia in preparation for implantation of an orthopedic joint replacement, the instrument comprising: (a) an intermedullary support comprising an alignment rod having a tapered portion terminating at a first end thereof and defining a longitudinal axis therethrough, the rod axially insertable into the distal medullary cavity of the femur and having an outer surface adapted to engage the femur whereby the rod is alignable within the femur and provides a surgical reference point, the rod having a second end extending a distance beyond the distal femur; (b) a cutting guide adjustably mountable to the second end of the rod and positionable about the distal end of the femur, the cutting guide having a plurality of femoral blade slots therethrough, each femoral blade slot adapted to operatively receive a blade whereby the blade is guided to perform osteotomies; (c) a tibial guide adjustably mountable to the second end of the rod, non-simultaneously with the cutting guide, and positionable about the proximal end of the tibia, the tibial guide having a plurality of tibial blade slots therethrough, each tibial blade slot adapted to operatively receive a blade whereby the blade is guided to perform osteotomies; and (d) a tibial locking arm slidably movable along the tibial guide and adapted to engage the proximal end of the tibia whereby the tibia is secured perpendicular to the femur.
