This study examines the two year survivorship of an anatomically designed UKA implant using a new robotically guided technology that has been shown to improve implant positioning and alignment.Introduction: Successful clinical outcomes following unicompartmental knee arthroplasty (UKA) depend on component positioning, soft tissue balance and overall limb alignment which can be difficult to achieve using manual instrumentation.A new robotically guided technology has been shown to improve post-operative implant positioning, and limb alignment in UKA.This multi-center study examines the survivorship of this robotically guided procedure coupled with a novel, anatomically designed UKA implant at two years post-operative.Methods: 273 patients (301 knees) in an initial series and part of an IRB approved study underwent robotically guided surgery to receive a medial UKA from two surgeons at separate institutions.All patients received a fixed bearing metal backed onlay as the tibial component.Patients were consecutive for each respective surgeon.Each patient was contacted at a minimum two year follow up and asked a series of 5 questions to determine implant survivorship and patient satisfaction.59 patients were either lost to follow up or deceased.201 (224 knees) patients were successfully enrolled in the study and surveyed.There were 109 male patients and 92 female patients; the average age was 72±10 years and the average BMI was 29.4±4.9 at the time of the index procedure.The average follow up was 32 ± 5 months.Results: One knee was reported as revised for an overall revision rate of 0.4% at a minimum two year follow up.The revision was reported due to mechanical failure and occurred 12 months after the index procedure; the patient returned to the same surgeon for the revision procedure.89% of patients reported feeling either "Very Satisfied" or "Satisfied".Conclusions: Excellent survival and satisfaction outcomes were noted in this subset of patients.This robotically guided procedure shows promise of improved survivorship rates for UKA compared to what is currently reported in implant registries and comparative studies.This study remains ongoing to include a larger cohort.
