背景：在单室膝关节置换术中，为了提高胫骨切割的准确性，实施了导航辅助膝关节置换术。据报道，使用导航系统的没有经验的外科医生比没有使用导航系统的有经验的外科医生取得了更好的对准效果。然而，还没有报告比较由有经验的外科医生和没有经验的外科医生进行的导航辅助下UKA的对位和临床结果。这项研究的目的是比较有经验和没有经验的外科医生在导航辅助下进行UKA时的这些参数。1名有经验的外科医生施行128次UKA(E组)，6名经验不足的外科医生施行81次UKA(I组)。胫骨冠状平面的目标值在内翻时设定为2.0度。结果：除活动度外，两组患者的假体对线和临床结果均无显著差异。I组手术时间明显长于E组(P
Background: To improve the accuracy of tibial cut during unicompartmental knee arthroplasty (UKA), navigation-assisted UKA has been implemented. It has been reported that inexperienced surgeons who use a navigation system achieve better alignment than experienced surgeons who do not use a navigation system. However, there have been no reports comparing the alignments and clinical outcomes of navigation-assisted UKA performed by experienced surgeons in comparison with that by inexperienced surgeons. This study aims to compare these parameters of navigation-assisted UKA performed by experienced and inexperienced surgeons.Methods: A total of 209 UKA procedures using an image-free navigation system were included. One experienced surgeon performed 128 UKAs (E group), and six inexperienced surgeons performed 81 UKAs (I group). The target value in the coronal tibial plane was set at 2.0 degrees in varus. Prosthetic alignments and clinical results were compared between the two groups.Results: No significant differences were found between the two groups for prosthetic alignments and clinical outcomes, except for range of motion. The operation time of the I group was statistically longer than that of the E group (P
