Abstract
A knee implant rotational alignment apparatus comprising a non-implantable femoral trial component having substantially the same configuration as a femoral implant, a cooperating tibial articulating trial component having two parallel guide rails protruding from the upper surface thereof, which rails engage with grooves in the lower surface of the femoral trial component, which engagement prevents rotation of the femoral trial component relative to the tibial articulating trial component in a transverse plane but allows flexion and extension rotation of both components, a tibial trial baseplate having an outer periphery substantially identical to the outer periphery of a tibial implant baseplate of corresponding size, which baseplate accommodates a spring clip activator the rotation of which facilitates selection of the rotational alignment of the prosthesis.
