OBJECTIVES
The present study had the objective of evaluating the effect of the use of intraoperative radioscopy in cases of primary knee arthroplasty, on the final alignment of the tibial component.
METHODS
Patients who underwent total knee arthroplasty (TKA) between April 13, 2013, and April 20, 2013, were included in the study. These patients were evaluated retrospectively and two groups were identified: one in which intraoperative radioscopy was used to assess the positioning of the tibial component during the surgery and the other in which this resource was not used.
RESULTS
The mean angle of alignment of the tibial component in relation to the tibial diaphysis was greater in the group without use of intraoperative radioscopy (90.82) than in the group with radioscopy (90.63), which was a statistically significant result (p < 0.05).
CONCLUSION
Use of intraoperative radioscopy during TKA produced a better mean angle of alignment between the tibial component and the tibial diaphysis, in comparison with nonuse.
目的
本研究旨在评估在初次膝关节置换术中使用术中透视对胫骨部件最终对线的影响。
方法
纳入2013年4月13日至2013年4月20日期间接受全膝关节置换术（TKA）的患者。对这些患者进行回顾性评估，并分为两组：一组在手术过程中使用术中透视来评估胫骨部件的位置，另一组未使用该资源。
结果
未使用术中透视的组中，胫骨部件相对于胫骨干的平均对线角度（90.82）大于使用透视的组（90.63），这是一个具有统计学意义的结果（p < 0.05）。
结论
与不使用术中透视相比，在TKA过程中使用术中透视可使胫骨部件与胫骨干之间产生更好的平均对线角度。
