本研究旨在量化全膝关节置换术（TKA）中股骨远端截骨与固定屈曲矫正之间的关系。之前的两项研究报告了相互矛盾的结果。连接到股骨试模部件的融合器模拟额外的股骨远端截骨，并使用计算机导航记录膝关节屈曲度。2 mm垫块产生的屈曲畸形平均为3.37 v，4 mm垫块产生的屈曲畸形平均为6.68 °，6 mm垫块产生的屈曲畸形平均为11.38 °。截骨前屈曲挛缩的程度显著影响每种垫块的效果。根据我们的结果，需要额外切除3.55 mm的股骨远端骨以矫正10 °固定屈曲，并且传统上认为TKA对屈曲畸形的矫正较少。(C)2016 Elsevier Inc. All rights reserved.
This study aims to quantify the relationship between distal femoral bone resection and correction of fixed flexion in total knee arthroplasty (TKA). Two previous studies have reported conflicting results. Spacers attached to the trial femoral component simulated additional distal femoral resection and the degree of knee flexion was recorded using computer navigation. The 2-mm augment produced an average of 3.37v of flexion deformity, 4-mm augment 6.68 degrees, and 6-mm augment 11.38 degrees. The amount of pre-resection flexion contracture significantly impacted on the effect of each augment. From our results, an additional 3.55 mm of distal femoral bone resection is required to correct 10 degrees fixed flexion and produced less correction of flexion deformity as traditionally believed in TKA.
