Abstract:
1. A method of trialing prosthetic components of a knee prosthesis, the method comprising positioning a polymer femoral trial component on a surgically-prepared distal end of a patient's femur, assembling a tibial bearing trial component, positioning the tibial bearing trial component on a tibial base trial component seated on a surgically-prepared proximal end of a patient's tibia, adjusting the patient's leg with the tibial bearing trial component engaging the polymer femoral trial component, removing the tibial bearing trial component from the tibial base trial component, inserting a keel punch into the surgically-prepared proximal end of the patient's tibia through an opening of the tibial base trial component, placing the tibial bearing trial component on the tibial base trial component and the keel punch, and readjusting the patient's leg with the tibial bearing trial component engaging the polymer femoral trial component after positioning the tibial bearing trial component on the tibial base trial component and the keel punch.
