Table 1 Correlation analysis between the ACL tibial footprint and other radiographic landmarks

From: Variations in sagittal locations of anterior cruciate ligament tibial footprints and their association with radiographic landmarks: a human cadaveric study

Radiographic landmarks Mean (range) SD CCb p valueb
Sagittal location of ACL tibial footprinta 40.9 (38.0 ~45.0) 2.0   
Geometry of Blumensaat’s line
 Sagittal location of Blumensaat’s linea 26.7 (22.0 ~34.0) 3.1 0.572 0.033
 Angle between Blumensaat’s line and tibia articular margin (°) 63.9 (57.8~74.0) 4.9 0.704 0.005

  1. aData are presented as the percentage that was measured by the proportion of sagittal landmark in Amis and Jakob’s line
  2. bStatistical analysis was performed using the Pearson’s correlation analysis
  3. Abbreviation: SD (standard deviation), CC (correlation coefficient
