Abstract
An instrument for utilization in the rotational alignment of a hinged prosthetic knee implant has two selectively coupled parts for mounting on the tibia. The prosthetic knee implant has a tibial portion and a femoral portion. The femoral component has a hinged portion. The first part of the instrument is a trial tibial template for engaging the resected proximal tibia. The second part is a trial hinge component that has a portion for selectively coupling with the trial template in an orientation forming the tibial portion of the prosthetic knee implant. The trial hinge component has a hinge portion which selectively mates with the hinge on the femoral component. The rotational alignment of the tibial portion of the prosthetic knee implant may be determined by coupling the hinged portion of the trial hinge component to the hinge on the femoral component and moving the resected tibia throughout the range of motion desired and pinning the trial tibia template in the appropriate position on the resected tibia.
