Patent ID: 8197489

Claim:
An orthopaedic surgical device, comprising a first sensor component comprising (i) a first paddle set having a first tibial paddle and a first femoral paddle that extend from the first sensor component in a general direction of extension to respectively contact a proximal tibia and a distal femur of a patient the first femoral paddle is moveable with respect to the first tibial paddle to determine a first displacement between the proximal tibia and the distal femur, (ii) a first tensor to apply a selected first force between the proximal tibia and the distal femur via the first paddle set, (iii) a first displacement scale to indicate the first displacement between the proximal tibia and the distal femur determined by the first paddle set, (iv) a housing having an upper end to which the first tibial paddle is coupled, (v) a first displacement cylinder having an upper end to which the first femoral paddle is coupled and a lower end telescopically coupled with the upper end of the housing, and (vi) a tensor cylinder having an upper end telescopically coupled with a lower end of the housing and the lower end of the first displacement cylinder, and a second sensor component coupled to the first sensor component, the second sensor component comprising a second paddle set having a second tibial paddle and a second femoral paddle that extend from the second sensor component in the general direction of extension to respectively contact the proximal tibia and the distal femur of the patient, the second femoral paddle moveable with respect to the second tibial paddle to determine a second displacement between the proximal tibia and the distal femur, wherein the first paddle set and second paddle set are moveable with respect to each other in the general direction of extension to permit selectively extending one of the paddle sets beyond the other paddle set in the general direction of extension.
