  • Publication number: 20240307072
    Abstract: Instrumentation and a method for unicompartmental knee replacement procedure are described. The surgical instrumentation may include a unicondylar posterior femoral cutting guide, a unicondylar tibial cutting block assembly and a unicondylar femoral cutting guide. The method may include inserting the unicondylar posterior femoral cutting guide into a joint gap while the knee is in flexion, resecting the posterior femoral condyle of the femur while the knee is in flexion, the surface of the resected posterior femoral condyle defining a reference plane, and setting the position of a unicondylar tibial cutting block on the tibia relative to the reference plane by using the resected surface of the posterior femoral condyle. The unicondylar femoral cutting guide may then be used to make one or more femoral cuts.
