An observational study in Total Joint Arthroplasty, sponsored by University of Utah. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-11-20.
Sponsored by University of Utah · Observational
The objectives of this study are:
In orthopaedic and trauma surgery post-operative mobility is very important. Six-month mortality and patient satisfaction has been associated with mobility. Elderly patients may suffer from severe complications caused by immobility due to a high prevalence of comorbidities.
Measuring postoperative mobility has primarily been based on advanced technology and complicated gait laboratories (treadmill, force plate, videoanalysis). The recent introduction of mobile insole force devices, such as the pedoped loadsol® (Novel) may allow for a cost-effective and clinically relevant use of providing biofeedback.
Using video analysis to evaluate the insole device will allow for measurements in realistic situations like walking stairs, stand up from a chair, sit down, turning and walking. The investigators had previously completed this in the lab setting and further the feedback mode of the loadsol will be used for training the patients in terms of symmetry after a total knee replacement.
This study may have an important influence on the aftercare of the investigators patients. Determining the postoperative mobility and evaluating gait analysis in real time will allow the investigators to compare between different operative approaches, operative techniques, Implants and more. If the feedback mode is working as expected the investigators might use it in the close future in the investigators standard aftercare for all patients.
