摘要： A device for performing a surgical procedure on a knee includes an adjustable femoral portion, a tibial. portion and at least one sensor coupled with the femoral and/or tibial portions to sense pressure exerted by the a moral and tibial portions against one another. The femoral portion is adapted for removably coupling with a distal end of a Femur to adjust tension in soft tissue adjacent the knee and has at least one positioning feature adapted to move relative to the distal end of the femur as the femoral portion is adjusted, thus helping position a femoral prosthetic on the distal end of the femur. The sensor(s) may he adapted to sense pressure at medial and lateral sides of the knee, and relative pressures may he displayed as data on a visual display. Adjustments to the femoral member may be made to balance pressure at flexion and extension of the knee.

摘要： Dynamic knee balancing devices, systems and methods provide for enhanced total knee arthroplasty (“TKA”) procedures. Devices generally include a stationary femoral member for removably attaching to a distal femur and an adjustable femoral member coupled with the stationary member for adjusting ligament tension of the knee. The adjustable femoral member includes at least one positioning feature for providing positional and/or orientation information for facilitating the TKA procedure. Additionally, the adjustable femoral member is movably couplable with a tibial member engaged with the proximal tibia to allow movement of the knee through a range of motion without removing the device from the joint space. When the adjustable femoral member is adjusted, the positional feature(s) move relative to the distal femur to provide positional information.

摘要： A method for positioning a bone cutting guide on a tibia may begin with coupling a bone cut positioning apparatus with a tibia. The method may also include adjusting the positioning apparatus in a varus/valgus orientation to shine a light emitted by a light emitter approximately along a midline of an anterior surface of the tibia, swinging a pivoting arm about a pivot joint to direct the emitted light along a medial surface of the tibia, adjusting the positioning apparatus in an anterior/posterior orientation to shine the light approximately along a midline of the medial surface, contacting a stylus with a proximal end of the tibia to select a cutting depth for a bone cut to be made on the tibia, and attaching the bone cutting guide to the tibia in a position determined by the positioning apparatus.

摘要： 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.
