Introduction: The outcomes of unicondylar knee arthroplasties (UKA’s) have demonstrated inconsistent long-term survival. In this study, we had the intention to report the clinical series of UKA using a semi-active robot system fort the implantation of an inlay unicondylar knee arthroplasty. Patients and Methods: 108 knees in 100 patients who underwent robotically-assisted tibiofemoral arthroplasty between November 2010 and November 2012 included in the study. Minimum follow-up was 24 months (mean 28 months). The patients with a broad BMI range and a wide range of deformity are included in this study. Oxford Knee Score (OKS), Knee Society Score ( KSS) and Functional Score were recorded in the clinical follow ups of patients. Results: The OKS improved from preoperative mean of 21.90±8.16 to a mean of 38.92±6.26, the KSS improved from preoperative mean of 53.69±11.23 to a mean of 86.37±9.31, the FS degree improved from preoperative mean of 46.81±16.25 to a mean of 80.80±13.43 at 2 years follow up. Conclusion: We noticed that OKS, KSS and FS was remarkably improved in the robotic unicondylar prosthesis patients with a broad BMI range and a wide range of deformity.
