The authors investigated the agreements between three different methods of estimating gap balance in cruciate-retaining (CR) total knee arthroplasty (TKA) with the use of a subvastus approach. One hundred consecutive CR TKAs were prospectively included in this study. After completing soft tissue release and bone cutting for CR TKA, flexion-extension gap balance was assessed using a distractor, spacer blocks, and trial components. Levels of agreement between the estimation techniques used were substantial. All three techniques were reliable in the assessment of gap balance. But, observations made during this study suggest that if more than one estimation technique is applied during CR TKA, the incidence of undetected gap imbalance can be reduced.
作者使用股直肌下入路，研究了三种不同方法在十字韧带保留型（CR）全膝关节置换术（TKA）中评估间隙平衡的一致性。本研究前瞻性纳入了连续100例CR TKA患者。在完成CR TKA的软组织松解和截骨后，使用撑开器、间隔块和试验组件评估屈伸间隙平衡。所用评估技术之间的一致性程度很高。所有三种技术在评估间隙平衡方面都是可靠的。但是，本研究中的观察结果表明，如果在CR TKA中应用不止一种评估技术，可以降低未检测到的间隙不平衡的发生率。
