Abstract
A device for performing a surgical procedure on a knee comprises a femoral assembly comprising a stationary femoral member attachable to the distal femur, an adjustable femoral member movably coupled with the stationary member to adjust tension in at least one ligament of or adjacent the knee and an adjustment mechanism coupled to the assembly. The adjustable member includes at least one positioning feature that moves relative to the distal femur as the adjustable member is adjusted and identifies at least one position on the distal femur. The adjustable member is movably couplable with a tibial member engaged with a proximal tibia to allow the knee to be moved through a range of motion without removing the femoral and tibial members. The mechanism includes an actuator positioned proximate a medial or lateral portion of the adjustable member. The actuator is configured to adjust an opposite portion of the adjustable member.
