Introduction Primary total knee arthroplasty has long been proven effective in the treatment of stage 3-4 knee osteoarthritis. It is well known that this intervention not only improves the quality of life, but also helps to restore the function of the joint and eliminate axial deformities.Purpose To compare early results of total knee arthroplasty using robot-assisted technology with conventional manual technique.Materials and Methods 20 patients diagnosed with stage 3 osteoarthritis of the knee joint and varus deformity of the knee joint axis were included in a prospective randomized study. Patients were divided into 2 representative groups, 10 subjects underwent robot-assisted knee arthroplasty, and the conventional manual technique was used in the other 10 patients. For clinical assessment, functional scales KSS, WOMAC, Lysholm Score were used, postoperative radiographs were evaluated.Results According to clinical functional scales, 10 days after surgery, there was an improvement in performance in the patients of both groups (p
