Abstract

Unicompartmental knee arthroplasty (UKA) is becoming a more prevalent treatment for medial-compartment arthritis. Traditionally, a competent anterior cruciate ligament (ACL) is required to achieve satisfactory results. This leads to the question of treatment for medial-compartment arthritis in the setting of an incompetent ACL. A treatment option for this subset of patients is concurrent UKA and ACL reconstruction; however, this technique addresses the cohort of patients with a previously stable UKA who sustain an injury to the ACL, leading to symptomatic instability. The purpose of this article is to detail a technique for ACL reconstruction in the setting of a previous UKA.
