Intervention / Traitement |
|---|---|
|
THA using direct-anterior surgical approach
Patients will have undergone THA using a direct-anterior surgical approach and will undergo fluoroscopy surveillance while walking.
|
While each subject performs a gait activity (normal walking) under fluoroscopic surveillance on a level treadmill, a data acquisition (DAQ) system will be used to determine the vibrations/sounds occurring during walking.
