Figures & data
Figure 1. Scatter plot comparing the degrees of mechanical axis deviation as measured by each independent observer. The slope of the best-fit line equals 0.98, indicating insignificant variability between measurements.
Figure 2. The dotted line indicates the average CAS TKA postoperative mechanical axis (1.99°). The data points indicate the average conventional TKA postoperative mechanical axis for each group of 30 consecutive patients.
Figure 3. Effect of preoperative mechanical axis (°) on postoperative mechanical axis (°) in CAS TKA (a), conventional TKA (b), and conventional TKA in patients with preoperative mechanical axes of 10.0° or less (c). The vertical dotted line indicates a postoperative mechanical axis of 3.0°, a deviation from neutral that is widely considered acceptable.
