Abstract：
BACKGROUND: In this study, the traditional \"Anatomical Landmark-Distance Method (AL-DM)\" in the formation of joint line (JL) was compared with \"Adductor Tubercle-Ratios method\" (AT-RM), and the effect of reestablishment of JL on clinical and functional outcomes were evaluated.
METHODS: 16 revision total knee arthroplasties (rTKAs) were performed by using \"AT-RM\" (group 1) and 16 rTKA by using \"AL-DM\" (group 2) in our clinic between 2015 and 2018. The data were prospectively collected and a total of 32 knees of 31 patients were analyzed. At the final follow-up, knee functions were evaluated by using Knee Society Score (KSS) knee and function, Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores, Short Form-36 (SF-36) questionnaires and physical examinations.
RESULTS: Postoperative flexion arc was higher in Group 1. KSS knee and function scores were better in group 1. In group1, JL was reestablished successfully in all revision rTKAs in terms of ATJL and the tibial tubercle TT-JL ratios. The improvement in KSS knee and function scores and WOMAC scores were also better in group 1. Measurements showed that the improvement in KSS scores increased as AT-JL and TT-JL distances approached the calculated values.
CONCLUSIONS: \"AT-RM\" was shown to be superior to the traditional distance method in terms of JL reestablishment. Functional results and patient satisfaction increased when JL was reestablished.

摘要：
背景：在这项研究中，将形成关节线(JL)的传统“解剖界标-距离法(AL-DM)”与“内收肌体-比率法”(AT-RM)进行了比较，并评估了JL重建对临床和功能结局的影响。
方法：在2015年至2018年期间，在我们的诊所使用“AT-RM”（第1组）和使用“AL-DM”（第2组）进行了16次rTKA。前瞻性收集数据，并分析了31例患者的32个膝盖。在最后的后续行动中，膝关节功能采用膝关节社会评分(KSS)评价,西安大略省和麦克马斯特大学关节炎指数（WOMAC）得分，简表36(SF-36)问卷和体检。
结果：第1组术后屈曲弧度较高。第1组KSS膝关节功能评分较好。在第1组中，就ATJL和胫骨结节TT-JL比率而言，在所有翻修rTKA中成功重建了JL。第1组KSS膝关节和功能评分及WOMAC评分的改善也较好。测量表明，随着AT-JL和TT-JL距离接近计算值，KSS得分的改善增加。
结论：\“AT-RM\”在JL重建方面被证明优于传统的距离方法。重新建立JL后，功能结果和患者满意度增加。
