Surgical accuracy and clinical outcomes of image‐free robotic‐assisted total knee arthroplasty

Abstract

AbstractBackgroundThe development of total knee arthroplasty (TKA) for knee osteoarthritis (OA) has a good reputation for its effectiveness in reducing joint pain and improving range of motion. We aimed to review our early results using the image‐free robotic‐assisted technology in knee arthroplasty.MethodsA total of 71 patients suffering from end‐stage OA knee receiving TKA operated by robotic‐assisted surgery between the years 2018 and mid‐2021 were recruited. Clinical and radiological outcomes were compared with age and sex‐matched control group (conventional TKA).ResultsThe radiological outcome showed significantly more postoperative lower limb alignment outliers in conventional side than robotic‐assisted sides. Postoperative knee scores were similar among both groups. Robotic‐assisted TKA required a longer implantation time but a shorter hospital stay.ConclusionRobotic‐assisted TKA achieved a lower rate of mechanical axis Outlier in the coronal and sagittal plane with a shorter hospital stay. Yet both methods achieve a similar functional outcome.
