Physical Activities That Cause High Friction Moments at the Cup in Hip Implants
The Journal of Bone & Joint Surgery, 2018, doi: 10.2106/JBJS.17.01298

Selected data samples of the in vivo measured hip joint loads are available at the OrthoLoad Database.

In the diagrams and tables the moments are given in the dimension %BWm (percent of body weight times meter). To get the value of the highest moment Mmax (1) in the dimension Nm instead, multiply the value of Mmax in %BW*m (2) with 1% of the BW in N (3). In the example, the maximum moment is Mmax = 1.34 * 8.58 Nm = 11.5 Nm.
