Knee OA affects more frequently both joints. The involvement of the medial compartment involves an axis deviation of both limbs. The solution allows unicompartmental prosthetic restoration of articular defect and the axis of the patient's physiological load. Many studies have shown that the simultaneous prosthetic solution, compared to excellent results as regards the functional rehabilitation, increases the perioperative risks. Our experience with robotic surgery (Makoplasty), allowed us to show that this procedure reduces maximally perioperative risks, given the less invasive procedure compared to traditional methods, and how can ensure the same clinical result in the two joints in terms of restoration of joint biomechanics that of the axis of load.

Introduction

Isolated lateral compartment osteoarthritis (OA) occurs in 5–10% of knees with OA [1, 2]. Lateral unicompartmental knee arthroplasty (LUKA) emerged as a treatment to this disease in the early 80s but challenging surgical technique has limited the prevalence of this treatment option [1–3]. A robotic-arm assisted surgical technique (MAKO Surgical Corp.) has emerged as a way to achieve precise implant positioning which can potentially improve surgical outcomes.
