The Surgical Steps for Mobile Medial Partial Knee Arthroplasty
This chapter will review the surgical indications and surgical steps to perform a successful mobile bearing medial partial knee replacement. The main indication for mobile bearing medial partial knee replacement (PKR) is the pathoanatomic disease pattern “anteromedial osteoarthritis.” This is present when the ACL is intact and the lateral compartment has preserved cartilage. The surgical steps of a mobile bearing PKR involve restoring the joint line in both flexion and extension through a calibrated milling system or a gap balancing technique. This results in normal knee kinematics and low polyethylene wear rates.
