Abstract:
1. A device for enhancing a surgical procedure on a knee, the device comprising: a tibial member having a pair of complementary depressions, said tibial member being engageable with a surface of the proximal tibia; at least one stationary femoral member for removably attaching to a distal femur; and at least one adjustable femoral member having a first surface disposed to contact the tibial member when the knee is in extension and having a posterior condylar member including a medial femoral posterior condylar portion and a lateral femoral posterior condylar portion, said posterior condylar member being disposed at a substantially right angle relative to the first surface so that the medial and lateral femoral posterior condylar portions slidingly contact the complementary depressions in the tibial member when the knee is in flexion, said adjustable femoral member being movably engaged with the stationary femoral member to adjust tension in at least one ligament of the knee, the adjustable femoral member including an adjustment member that moves the adjustable femoral member in an anterior-posterior direction relative to the stationary femoral member for facilitating completion of the surgical procedure to enhance range of motion, stability or patella tracking of the knee; wherein the adjustable femoral member is movably engageable with said tibial member engaged with a proximal tibia to allow the knee to be moved through a range of motion from a fixed position to an extended position without removing the femoral and tibial members.
