Abstract: | IntroductionRobotic-assisted unicompartmental knee arthroplasty (UKA) is associated with improved component positioning and comparable short- and mid-term implant survivorship with manual UKA. This study aims to evaluate clinical and radiological outcomes following robotic-assisted UKA as well as any potential learning-curves associated with the introduction of such new technology.MethodsProspective study of patients undergoing robotic-assisted UKA. Outcome measures were patient-reported outcome measures (PROMs) including Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee Society Score (KSS) and Oxford Knee Score (OKS), complications, implant survivorship, component positioning and learning curve.ResultsEighty-five patients comprising 100 knees were recruited and followed up for 21.0 ± 4.3 months. At two years, there were significant and sustained improvements in PROMs and 100% implant survivorship rate. A high degree of implant accuracy was achieved with the robotic system. A cumulative learning curve of 20 cases was noted.ConclusionRobotic-assisted UKA achieves excellent implant accuracy and clinical outcomes in the short-term. Long-term follow up is needed to evaluate this relationship. |
