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 be adapted to sense pressure at medial and lateral sides of the knee, and relative pressures may be 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： A method for positioning a bone cutting guide on a tibia may involve coupling a cutting guide positioning apparatus with a tibia, adjusting the positioning apparatus in a varus/valgus orientation, adjusting the positioning apparatus in an anterior/posterior orientation, adjusting the positioning apparatus up or down to select a tibial bone resection level, and contacting a cutting guide with the tibia, using the adjusted positioning apparatus.

摘要： A kit (10) for resection of bone (12) for use in implantation of a joint prosthesis (14) is provided. The kit (10) includes a guide (16), a tool (26) and a stop (32). The guide (16) defines an opening (20) through the guide (16). The guide (16) is in cooperation with the bone (12). The tool (26) may be constrained within the opening (20) of the guide (16). The tool (26) includes a cutting edge (30) for resection of bone (12). The stop (32) cooperates with the guide (16) and the tool (26) to limit the movement of the tool (26) within the guide (16) so that the position of the cutting edge (30) with respect to the bone (12)m may be controlled. The stop (32) includes a plurality of positions (34) with respect to the tool (26) and the guide (16).
