摘要

背景：适当的软组织平衡对于全膝关节置换术（TKA）至关重要。目前广泛应用的评估软组织平衡的技术是利用张力装置、机器人和导航来测量关节间隙。我们比较了使用张紧器、导航和机器人工具评估的软组织平衡。方法纳入81例行双十字稳定（BCS） TKA的患者。41例采用导航（N组），40例采用机器人（R组）。最终植入后，N组采用张紧器（JLT）和导航器（JLN）测量关节松弛度，r组采用张紧器和机器人（JLR）测量关节松弛度，分别在屈曲10°、30°、60°和90°时进行评估。比较两组采用不同工具评估的关节松弛度。结果两组间各屈曲角度的jlt均无明显差异。在90°时，jlt大于jlt。在30°、60°和90°处，JLTs大于JLRs。在膝关节屈曲角度为60°时，jlt与jlr之间的差异大于jlt与JLNs之间的差异。侧室60°和90°处jlt小于JLNs。结论采用张紧器对两个隔室分别施加80 N的牵张力评估关节松弛度与机器人和导航在伸直位置评估关节松弛度相似。然而，使用张力装置评估的关节松弛度比机器人和导航在屈曲位置评估的关节松弛度大。

Assessment of joint laxity following total knee arthroplasty: A comparison of tensioner device, navigation, and robot evaluation

Background

Appropriate soft-tissue balance is essential for total knee arthroplasty (TKA). Widely used techniques to evaluate soft-tissue balance are measuring the joint gap using tensioner devices, the robot and the navigation. We compared soft-tissue balance evaluated using tensioner, navigation, and robot tools.

Methods

81 patients who underwent bi-cruciate stabilized (BCS) TKA were included. 41 patients were performed using the navigation (Group N) and 40 patients were performed using the robot (Group R). After the final implantation, the joint laxities were measured using tensioner device (JLT) and navigation (JLN) in group N and measured using tensioner device and robot (JLR) in group R. The evaluations were performed at a flexion of 10°, 30°, 60° and 90°. Joint laxities evaluated by the different tools were compared in both groups.

Results

No significant between-group differences were observed for JLTs at each flexion angle in both compartments. The JLTs of were larger than JLNs at 90°. The JLTs were larger than JLRs at 30°, 60°and 90°. At a knee flexion angle of 60°, the difference between JLTs and JLRs were larger than that between JLTs and JLNs. The JLTs were smaller than JLNs at 60°and 90°in the lateral compartment.

Conclusion

Joint laxities evaluated using the tensioner device with a distraction force of 80 N for both compartments were similar to those evaluated with the robot and the navigation in extension position. However joint laxities evaluated using the tensioner device were larger than those evaluated with robot and the navigation in flexion position.
