Abstract

An apparatus, system, and method for compensating for bone loss of a patient's knee joint during the performance of an orthopaedic surgical procedure includes determining an estimated amount of bone loss of a bone of a patient's knee joint, determining an anatomical distance between a femoral anatomical feature of a patient's femur and a tibial anatomical feature of a patient's tibia, and adjusting the determined anatomical distance based on the estimated amount of bone loss. The determined anatomical distance is indicative of a ligament length of a collateral ligament of the patient's knee joint. The bone loss may be estimated based on, for example, a surface curve fitting algorithm applied to a three-dimensional model of the bone, a defined bone loss amount provided by a user, or a comparison of the three-dimensional model of the bone to a statistical shape model that approximates the bone in a healthy state.
