Unicondylar Knee Arthroplasty Made Simple

Abstract

Unicompartmental knee arthroplasty (UKA) has become an increasingly used procedure for patients with unicompartmental knee osteoarthritis. The success of UKA relies on appropriate patient selection and patient optimization before surgery is performed. Improved prosthesis design and surgical techniques for medial and lateral and fixed and mobile bearing UKA have also contributed to improved knee biomechanics, faster recovery, and improved outcomes. Indications, factors affecting patient selection, the role of limb alignment, and the surgical pearls for fixed and mobile bearing and medial and lateral UKA are important topics for discussion.
