ABSTRACT
Background The aim of this study was to compare the clinical and radiologic outcomes robot-assisted unicompartmental knee arthroplasty (UKA) those conventional UKA in Asian patients. Methods Fifty-five patients underwent 57 were assessed study. Preoperative postoperative range motion (ROM), American Knee Society (AKS) score, Western Ontario McMaster University Osteoarthritis Index scale score (WOMAC), patellofemoral (PF) values compared between two groups. mechanical femorotibial angle (mFTA) Kennedy zone also measured. Coronal alignments femoral tibial components posterior slopes component compared. Additionally, polyethylene (PE) liner thicknesses Results There no significant difference groups regarding ROM, AKS, WOMAC PF score. Robot group showed fewer outliers terms mFTA coronal alignment (p = 0.022, 0.037, 0.003). significantly different PE (8.4 ± 0.8 versus 8.8 0.9, p 0.035). only influencing factor for reducing outlier (postoperative mFTA) multivariate model (odds ratio: 2.833, 0.037). Conclusion In study, had many advantages over UKA, such as its ability achieve precise implant insertion reduce outliers. Although a short-term follow-up period not longer is needed determine whether improved accuracy robotic-assisted will lead better long-term survival.
