Abstract

Introduction: Robotic assisted total knee arthroplasty (RATKA) was proven that improved component position, ligament balanced and decreased outlier leading to improved clinical results and implant survivorship. Aiming of this study is comparison of short-term clinical and radiologic outcomes between RATKA versus conventional TKA (CMTKA) in Thabo Crown Prince Hospital, Thailand.
Methods: Retrospective cohort study by single surgeon, from July 2020 to August 2022 compared 51 RATKA and 49 CMTKA. Baseline data and short-term clinical outcomes including knee society score (KSS), operative time, estimated blood loss (EBL), length of stay (LOS), complications and radiologic outcomes were collected at postoperatively 3 months follow up.
Results: There was no statistically significant difference in KSS, EBL, LOS and complications between RATKA and CMTKA (P < 0.05). Operative time was significant greater in RATKA (138 vs. 162 min, P < 0.05). Radiologic outcomes in CMTKA, posterior condylar Offset, posterior condylar deviation, tibial slope was significant higher (P < 0.05). In subgroup analysis, patients with post operative tibial slope ≥ 7° (poor clinical outcomes) in CMTKA significantly higher than in RATKA (P = 0.021).
Conclusions: Imageless - robotic assisted total knee arthroplasty demonstrated that more benefit in posterior condylar offset and posterior tibial slope restoration and seem to be better in short-term clinical outcomes.
