Functional results and survivorship after medial unicompartmental knee arthroplasty: a single center experience from Saudi Arabia.

Background: Isolated involvement of the medial compartment of the knee in degenerative disease is encountered in about 25% of patients with gonarthrosis. We aim to show that in a well-selected group of such patients, medial unicompartmental knee arthroplasty (UKA) is a good option.

Objectives: Review the functional outcomes of patients undergoing UKA and determine the long-term survivorship of the implants and complications of the procedure.
