Abstract:
1. An adjustable resection guide for guiding a cutter to cut bone adjacent a knee joint to prepare the bone to receive an implant, the knee joint including articulating ends of a tibia and a femur and having a medial aspect, a lateral aspect, an anterior aspect, and a posterior aspect, the tibia having a tibial axis extending from a proximal end near the knee joint to a distal end near an ankle joint, the guide comprising: an elongated base member having a proximal end, a distal end and a longitudinal axis therebetween, the base member being positionable adjacent the tibia with the longitudinal axis parallel to the tibial axis; a tibial cut guide having a guide surface for guiding a cutter to cut the tibia; a mediolateral adjustment mechanism interposed between the base member and the tibial cut guide, the mediolateral adjustment mechanism operable to adjust the tibial cut guide mediolaterally relative to the base member; a proximal-distal adjustment mechanism interposed between the base member and the tibial cut guide, the proximal-distal adjustment mechanism operable to adjust the tibial cut guide proximal-distally relative to the base member independently of the mediolateral adjustment, the mediolateral and proximal-distal adjustment mechanisms permitting the tibial cut guide to be positioned at a desired location adjacent the proximal tibia; and a modular femoral cut guide mountable to the tibial cut guide in relative mediolateral translating relationship, the femoral cut guide having a guide surface for guiding a cutter to cut the femur.
