Reliability of Roentgenographic Knee Alignment Measurements in Gonarthrosis: Methodological Issues to Avoid Misinterpretation

摘要

I was interested to read the article by Huang et al published in the Journal of Knee Surgery, 2018. A reliable method of measuring knee alignment is critical in the preoperative planning of high tibial osteotomy (HTO). There are two commonly used methods for measuring knee alignment: the mechanical axis and the anatomical axis. The authors aimed to determine which method would be more reliable and reproducible. Fifty consecutive patients (50 knees) with medial gonarthrosis were treated with valgus-producing HTO.
