Fig. 1From: Computer-assisted total knee arthroplasty using mini midvastus or medial parapatellar approach techniqueBoxplot of the mechanical leg axis (degrees) for MIS and conventional TKA groups. The mean mechanical leg axis in the conventional group was 0.97° ± SD 1.87°, in the MIS group 0.54° ± SD 2.53°. The difference of the mean mechanical leg alignment between the groups was not statistically significant (‐0.43° (95 % CI ‐1.50 - 0.64); p = 0.43)Back to article page
