Robot-assisted Knee Arthroplasty: Randomized Clinical Trial

BACKGROUND: Osteoarthritis of the knee joint leads to a decrease in volume movements, violation sliding articular surfaces, and change axis limb under load, which affects biomechanics walking. AIM: This study aims compare results robot-assisted total arthroplasty (TKA) manual techniques, their influence on biomechanical podometric parameters patient’s walk. METHODS: A prospective randomized 68 patients was carried out period from 2020 2021. Our follow-up 1 year. All were performed one joint. The main Group “A” included 33 TKA with use an active robotic setting “TSolution-One” (“THINK Surgical, Inc.” [Fremont, California, USA]); comparison “B” consisted 35 technic TKA. We studied pain syndrome visual analog scale, functional state Oxford Knee Score (OKS) Western Ontario McMaster Universities Arthritis Index (WOMAC), ROM deviation mechanical by teleroentgenography lower limb. Objective analysis function «Alter-G» «C-mill». RESULTS: Post-operative 1st day after surgery is stronger 7.9%, but 5th A, 14.3%. better 16% 3 months surgery, year 10%. positioning accuracy implant 30% better. There are no statistically significant differences OKS WOMAC scales between groups. restoring normal step 13.5% than B. CONCLUSIONS: Robot-assisted gives more accurate alignment axis, improves
