| 目的 比较机器人辅助功能学对线全膝关节置换术（FA-RTKA)与传统方法机械学对线全膝关节置换术（MA-TKA）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）患者的临床和影像资料，按术式分为FA-RTKA组46例（48膝）与 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2011版美国膝关节协会评分（2011KSS）和遗忘关节评分（FJS-12）。 结果 FA-RTKA组的手术时间较MA-TKA组延长（P＜0.05），围术期失血量更少（P＜0.05）,软组松解率显著更低（P＜0.05）。FA-RTKA组术后JLO和CPAK分型保持与术前一致的比例更高（P＜0.05）。FA-RTKA组术后1个月的2011 KSS客观及主观评分优于MA-TKA组（P＜0.05），术后3个月的2011 KSS主观评分、FJS-12评分均优于MA-TKA组（P＜0.05），术后6个月的FJS-12评分优于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关节线倾斜度方面具有一定优势，早期临床疗效更好。 |

| Abstract: |
| Objective To compare the short-term outcomes of robot-assisted functional alignment in total knee arthroplasty (FA-RTKA) versus conventional mechanical alignment in total knee arthroplasty (MA-TKA). Methods A retrospective analysis was conducted on clinical and imaging data from 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 two groups based on the surgical technique, including the FA-RTKA group (46 cases, 48 knees) and the MA-TKA group (48 cases, 49 knees). Surgical-related indicators were compared between the two groups, including operative time, perioperative blood loss, and soft tissue release extent. Imaging parameters were analyzed according to the coronal plane alignment classification of the knee joint (CPAK), including arithmetic hip-knee-ankle angle (aHKA), joint line inclination (JLO), and CPAK phenotype. Clinical outcomes were evaluated at 1, 3, 6 months postoperatively using the 2011 American Knee Society Score (2011KSS) and the Forgotten Joint Score (FJS-12). Results The FA-RTKA group exhibited significantly longer operative time (P＜0.05), less perioperative blood loss (P＜0.05), and markedly lower soft tissue release rates (P＜0.05) compared with the MA-TKA group. The proportion of patients maintaining preoperative alignment status in terms of JLO and CPAK classification was higher in the FA-RTKA group (P＜0.05). The FA-RTKA group demonstrated superior outcomes compared with the MA-TKA group at 1 month postoperatively, with higher objective and subjective scores on the 2011 KSS scale (P＜0.05). At 3 months, the FA-RTKA group showed better subjective KSS scores, WOMAC scores, and FJS-12 scores (P＜0.05), while the FJS-12 score at 6 months remained statistically superior (P＜0.05). Conclusion Compared with MA-TKA, FA-RTKA can reduce perioperative blood loss and minimize soft tissue dissection. This technique exhibits advantages in restoring the knee joint's inherent phenotype and joint line inclination, thus leading to superior early clinical efficacy. |
