Knee arthritis is one of the leading causes of disability and functional limitations in the United States and worldwide. Total knee arthroplasty results in good functional outcomes and high survival rates in patients who have tricompartmental arthritis. Bicompartmental knee arthroplasty is being used more often in patients who have arthritis that is isolated to two compartments: the patellofemoral compartment and either the medial or the lateral compartment. Bicompartmental knee arthroplasty preserves the kinematics, ligaments, and bone stock of the knee and is a good option for younger, active, high-demand patients who wish to return to their previous level of activity.
