Patent ID: 7601154

Claim:
An apparatus for cutting a tibia in support of a unicondylar knee surgery comprising: a unicondylar tibial alignment guide having a lateral tibia anchor; and a unicondylar tibial resection guide adjustably connectable to the unicondylar tibial alignment guide and configured to operate concurrently with the unicondylar tibial alignment guide including: an extended arm having at least one cutting guide surface; and a tibial resection guide base connected to the extended arm and operating to adjustably connect the unicondylar tibial resection guide to the unicondylar tibial alignment guide at a first location, wherein the lateral tibia anchor contacts the tibia below the unicondylar tibial resection guide and is connected to the unicondylar tibial alignment guide at a second location, a distance between the unicondylar tibial resection guide and the lateral tibia anchor is adjustable, the tibial resection guide base operates to adjust the distance between the unicondylar tibial resection guide and the lateral tibia anchor by sliding along the unicondylar tibial alignment guide and moving the first location of the unicondylar tibial resection guide towards or away from the second location of the lateral tibia anchor, and the lateral tibia anchor operates to pivot the unicondylar tibial resection guide towards or away from the tibia.
