摘要
Background This study was designed to analyze three tibial axis reference lines including the anterior tibial cortex （ATC） line, the fibular line （FL）, and the anatomical axis of tibia （AAT） line, to determine which line most closely parallels the mechanical axis （MA） of the tibia in the sagittal plane. The clinical relevance of the study is that through finding a reliable landmark on the leg, a surgeon may minimize posterior tibial slope measurement errors thereby and improving the technique for assuring proper alignment of total knee arthroplasty.
