背景：全膝关节置换术（TKA）是治疗终末期膝关节骨关节炎（OA）的唯一有效方法。下肢中立位对线一直是预测假体寿命的标准，然而，最近对此存在争议。有研究者认为下肢静态对线对假体寿命影响不大，也有研究者发现动态力学对线可能影响假体寿命，有待进一步研究。研究方法：对87例膝关节OA患者在TKA术前和术后6个月进行三维步态分析，计算动态力学对线和基本步态参数。根据术后X线片上下肢的静态对线情况，将其分为中立对线组（58例）、内翻对线组（20例）和外翻对线组（9例）。简单线性回归用于评估静态和动态对准之间的相关性。单因素方差分析（ANOVA）用于比较组间和组内步态参数的差异。结果：87例患者术后平均随访6个月。三组患者术后步态参数无显著性差异。尽管患者在术前表现出显著的线性相关性，但在TKA术后未发现静态对线和动态对线/膝关节内收力矩（KAM）之间存在相关性。术前、术后动态对线与KAM呈显著线性相关。结论：静态对线对术后步态功能无明显影响。静态对线不再是TKA后6个月动态对线或KAM的有效预测因子，尽管它们在TKA前是相关的。动态对准允许更好地预测KAM，这可能是假体寿命的风险因素。
Background: Total knee arthroplasty (TKA) is the only effective treatment of end-stage knee osteoarthritis (OA). Lower limb neutral alignment has been a criterion to predict prosthesis life; however, there has been recent controversy over this. Some researchers believe that lower limb static alignment does not significantly affect prosthesis life and some researchers have found that dynamic mechanical alignment may affect prosthesis life, which needs to be further studied. Methods: Eighty-seven patients with knee OA were evaluated by a three-dimensional (3D) gait analysis system before TKA and six months after TKA, dynamic mechanical alignment and basic gait parameters were then calculated. Based on the static alignment of the lower limb on the postoperative X-radiographs, they were divided into a neutral alignment group (58 cases), varus alignment group (20 cases), and valgus alignment group (9 cases). Simple linear regression was used to assess the correlation between static and dynamic alignment. One-way analysis of variance (ANOVA) was used to compare the differences in gait parameters between and within groups. Results: Eighty-seven patients were followed up for an average of six months after the operation. There was no significant difference in all gait parameters among the three groups after TKA. There was no correlation found between static alignment and dynamic alignment/knee adduction moment (KAM) after TKA, although patients showed a significant linear correlation before operation. There was a significant linear correlation between dynamic alignment and KAM before and after the operation. Conclusions: Static alignment has no significant effect on postoperative gait function. Static alignment is no longer an effective predictor of the dynamic alignment or KAM six months after TKA, although they are correlated before TKA. The dynamic alignment allows for better prediction of KAM, which may be a risk factor for the life of the prosthesis.
