| ［摘要］ 目的 研究机器人辅助功能学对线全膝关节置换术（FA-RTKA）的短期疗效。方法 回顾性分析2023年3月至2025年9月于广西壮族自治区人民医院接受全膝关节置换术（TKA）的94例（97膝）患者的临床资料，按术式分为FA-RTKA组（46例，48膝）和MA-TKA组（48例，49膝）。比较两组手术相关指标，包括手术时间、围术期失血量、软组织松解情况。根据膝关节冠状面对线（CPAK）分型进行影像学评估，比较两组手术前后算术髋膝踝角（aHKA）、关节线倾斜度（JLO）、CPAK分型的变化情况。评估临床疗效，包括术后1、3、6个月的美国膝关节协会评分（KSS）和遗忘关节评分（FJS-12）。结果 与MA-TKA组比较，FA-RTKA组手术时间较长，围术期失血量较少，术中软组织松解率较低，术后JLO类型和CPAK分型与术前一致的比例较高，差异有统计学意义（P<0.05）。FA-RTKA组术后1个月的KSS客观及主观评分显著高于MA-TKA组（P<0.05），术后3个月KSS主观评分、FJS-12显著高于MA-TKA组（P<0.05），术后6个月的FJS-12显著高于MA-TKA组（P<0.05）。结论 与MA-TKA相比，FA-RTKA可减少围术期失血量，减少软组织松解，在维持膝关节表型和JLO方面具有一定优势，早期临床疗效更好。 |

| ［Abstract］ Objective To study the short-term outcomes of functionally aligned robotic-assisted total knee arthroplasty(FA-RTKA). Methods A retrospective analysis was conducted on the clinical data of 94 patients(97 knees) who underwent total knee arthroplasty(TKA) in the People′s Hospital of Guangxi Zhuang Autonomous Region from March 2023 to September 2025. All the patients were divided into FA-RTKA group(46 cases, 48 knees) and conventional mechanically aligned total knee arthroplasty(MA-TKA) group(48 cases, 49 knees) according to the surgical techniques. The surgical-related indicators were compared between the two groups, including operative duration, perioperative blood loss, and the extent of soft tissue releases. The imaging evaluations were conducted according to the Coronal Plane Alignment of the Knee(CPAK) classification. The changes in arithmetic hip-knee-ankle angle(aHKA), joint-line inclination(JLO) and CPAK classification were compared between the two groups before and after surgery. The clinical outcomes were evaluated at 1, 3 and 6 months postoperatively using the American Knee Society Score(KSS) and the Forgotten Joint Score-12(FJS-12). Results Compared with the MA-TKA group, the FA-RTKA group had significantly longer operative duration(P<0.05), less perioperative blood loss(P<0.05), and lower intraoperative soft tissue release rate(P<0.05), and the FA-RTKA group had significantly higher proportions of the patients whose JLO types and CPAK classifications after the operation kept consistent with those before the operation(P<0.05). One month after the operation, the objective KSS and subjective KSS values in the FA-RTKA group were significantly higher than those in the MA-TKA group(P<0.05). Three months after the operation, the subjective KSS and FJS-12 values in the FA-RTKA group were significantly higher than those in the MA-TKA group(P<0.05). Six months after the operation, the FJS-12 values in the FA-RTKA group were significantly higher than those in the MA-TKA group(P<0.05). Conclusion Compared with MA-TKA, FA-RTKA can reduce perioperative blood loss and soft tissue releases, and has advantages in keeping the knee joint phenotype and JLO, thus leading to better early clinical outcomes. |
