ABSTRACT
Objective To determine the angles of trochlear line(TL), antero-posterior line (APL) and posterior condylar line (PCL) with clinical epicondylar axis (CEA), analyze the variability difference in 3 axes relative to CEA. Methods The right knees in 36 patients with knee osteoarthritis (gradeⅣ) and who had underwent total knee arthroplasty were enrolled in this study, 11 male patients aged 60-81 (69.1 ± 6.3) years and 25 female patients aged 33- 85(67.7 ± 12.2) years. All of right knees were scanned using computed tomography. The angles between the CEA and each of the 3 axes (TL, PCL, APL) were measured using software. Results The angles of TL-CEA, APL-CEA and PCL-CEA was (6.10 ± 3.22)°, (85.80 ± 2.86)°and (2.70 ± 1.80)°. The F tests showed that the angel invariability between the TL and CEA the APL axis (α=0.58) or the PCL (α=0.28) for referencing the CEA had no significant differences. Conclusions The TL can be a relatively reliable reference axis to determine rotational alignment of the femoral component similar to PCL and APL.
