Fig. 4From: The superior accuracy of a novel method in total hip wear calculations following radiographic measurementThe conventional method to calculate the bedding-in and wear rate. Pk was calculated for each postoperative period (tk) using Eq. (6). The best-fit line for multiple penetration data (tk, Pk) was identified using the least-squares method. The wear rate and bedding-in were indicated by the slope (Wc) and y-intercept (Bc) of the line, respectivelyBack to article page
