Fig. 4From: Effects of extremity positioning on radiographic evaluation of femoral tunnel location with digitally reconstructed femoral lateral radiographs after anterior cruciate ligament reconstructionFemoral ACL tunnel aperture location expressed as percentage along the line perpendicular to the Blumensaat’s line (%DP) in relation to degree of rotation for various rotation types. For valgus rotation, P values were significant (P < 0.05) only for compared degrees - ‘0 vs 10’, ‘0 vs 15’, ‘0 vs 20’, and ‘5 vs 15’. For varus rotation, P values were not significant (P > 0.05) for all pair-wise comparisons. For external rotation, P values were significant (P < 0.05) only for compared degrees - ‘0 vs 10’, ‘0 vs 15’, ‘0 vs 20’, ‘5 vs 15’, and ‘5 vs 20’. For internal rotation, P values were significant (P < 0.05) only for compared degrees – ‘0 vs 10’, ‘0 vs 15’, ‘0 vs 20’, ‘5 vs 10’, and ‘5 vs 15’Back to article page
