Use of Tekscan K-Scan Sensors for Retropatellar Pressure Measurement Avoiding Errors during Implantation and the Effects of Shear Forces on the Measurement Precision
Figure 5
Relative decrease of the patellofemoral force over 12 measurement cycles with linear regression line for the measurements at 30 and 40 Nm. The first measurement cycle at 20 and 40 Nm is shown as 100%. Measurement cycles 1–3 and 7-8, 30 Nm torque. Measurement cycles 4–6 and 10–12, 40 Nm torque.
