Hip joint center (HJC) errors and soft tissue artifact (STA) measured dynamically.
- class="label">•
HJCs were generated from dual fluoroscopy (DF) and skin marker (SM) solutions.
- class="label">•
HJC errors were 16.6 mm and 11.7 mm when using SM and DF solutions, respectively.
- class="label">•
STA caused 2.2 mm (3.1 mm) of spurious HJC movement for 6 DOF (3 DOF) hip motion.
- class="label">•
STA led to 17.2 ± 5.3 mm error in tracking the position of the pelvis.
