摘要

目的：本研究的目的是比较机器人辅助（RA）和传统的基于夹具的双十字保留全膝关节置换术（BCR TKA）术后短期患者报告的结果测量（PROMs）。方法对33例RA-BCR TKA患者（Robot组）和32例常规TKA患者（conventional组）进行回顾性单外科连续队列分析。通过三维计算机断层扫描（3DCT）测量比较两组股骨外侧远端角（LDFA）、胫骨内侧近端角（MPTA）、股骨和胫骨组件旋转对齐、股骨远端和股骨后侧截骨（mm）。术后1年多收集膝关节社会评分（KSS）、西安大略和麦克马斯特大学关节炎指数（WOMAC）、遗忘关节评分和髌骨评分。结果Robot组术前膝关节评分（平均值：20.5）明显高于常规组（平均值：16.8），而功能评分（平均值：57.7）明显低于常规组（平均值：69.6）。机器人组在术后伸展角（p < 0.01）和2011年KSS的标准和高级活动（p < 0.01）方面有明显更大的改善。两组间LDFA、MPTA和股骨及胫骨组件旋转对中无显著差异。常规组股骨内侧远端截骨（mm）明显大于常规组（p < 0.01）。机器人组股骨后外侧截骨（mm）明显大于机器人组（p < 0.01）。与常规组相比，机器人组有更多的关节线恢复和后髁外侧偏移减少的病例。结论RA-BCR TKA比常规TKA更能改善2011年KSS的术后伸展角和标准及晚期活动。证据等级三级。

Purpose

The aim of this study was to compare post-operative short-term patient-reported outcome measurements (PROMs) between robotic-assisted (RA) and the conventional jig-based technique using bi-cruciate retaining total knee arthroplasty (BCR TKA).

Methods

This retrospective single-surgeon consecutive cohort analysis compares 33 RA-BCR TKA patients (Robot group) to 32 conventional TKA patients (Conventional group). Lateral distal femoral angle (LDFA), medial proximal tibial angle (MPTA), femoral and tibial component rotational alignment, distal and posterior femoral osteotomy (mm) were compared between the two groups using three-dimensional computed tomography (3DCT) measurements. 2011 Knee Society Score (KSS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Forgotten Joint Score and Patella score were collected more than 1 year after surgery.

Results

Pre-operative knee scores were significantly higher in the Robot group (mean: 20.5) than in the Conventional group (mean: 16.8), while functional scores were significantly lower in the Robot group (mean: 57.7) than in the Conventional group (mean: 69.6). The Robot group showed significantly greater improvements in post-operative extension angle (p < 0.01), and standard and advanced activity in the 2011 KSS (p < 0.01). LDFA, MPTA and rotational alignment of the femoral and tibial components showed no significant difference between the two groups. Medial distal femoral osteotomy (mm) was significantly greater in the Conventional group (p < 0.01). Lateral posterior femoral osteotomy (mm) was significantly greater in the Robot group (p < 0.01). The robotic group had significantly more cases of joint line restoration and reduced lateral posterior condylar offset than the Conventional group.
