Abstract

Background: Achieving proper axis alignment can be difficult in the presence of posttraumatic extra-articular deformities in either the femur or the tibia. We present radiological outcomes following robot-assisted total knee arthroplasty (TKA) in patients with osteoarthritis of the knee accompanied by posttraumatic extra-articular deformities.

Methods: We analyzed the outcomes of five knees in five patients with (1) Kellgren-Lawrence (K-L) Grade III-IV osteoarthritic knees, (2) the presence of posttraumatic extra-articular deformities either in the femur or the tibia, and (3) who underwent robot-assisted TKA. Their radiological findings were evaluated.

Results: All five knees with initial deformity (mean 14.8°, range 12.7-18.5°) were corrected to neutral alignment (mean 0.7°, range -1.1-2.7°). There was no postoperative outlier of hip-knee-ankle (HKA) angle.

Conclusion: Our results indicate that robot-assisted TKA can be used to achieve proper limb alignment in patients with posttraumatic extra-articular deformities.

使用机器人辅助全膝关节置换术治疗创伤后冠状面畸形:一个病例系列。

背景:在股骨或胫骨创伤后关节外畸形的情况下，实现适当的轴对齐可能是困难的。我们介绍了机器人辅助全膝关节置换术(TKA)对伴有创伤后关节外畸形的膝关节骨性关节炎患者的放射学结果。方法:我们分析了5例患者(1)Kellgren-Lawrence (K-L) III-IV级骨关节炎膝关节，(2)股骨或胫骨存在创伤后关节外畸形，(3)接受机器人辅助TKA的患者的5个膝关节的结局。对他们的放射学表现进行了评估。结果:所有初始畸形的5个膝关节(平均14.8°，范围12.7-18.5°)均被矫正为中立位(平均0.7°，范围-1.1-2.7°)。术后髋关节-膝关节-踝关节(HKA)角度无异常值。结论:我们的研究结果表明，机器人辅助的TKA可以用于创伤后关节外畸形患者实现正确的肢体对准。
