An observational study in Rheumatoid Arthritis, sponsored by Leiden University Medical Center. Completed at 1 site in Netherlands. Per ClinicalTrials.gov, last updated 2010-04-13.
Sponsored by Leiden University Medical Center · Observational
The aim of this study is to accurately assess the relationship between knee joint kinematics and migration of the tibial component of a high congruent, rotating platform total knee prosthesis by using fluoroscopy synchronised in time and space with a force plate, an external motion registration system and Electromyography (EMG).
3,554 studies on the registry are indexed under Arthritis; 318 are open to participants now.
This study's enrollment of 11 is below the median of 155 across 1,057 observational studies indexed under Arthritis.

Exclusion Criteria:
Migration
Roentgen stereophotogrammetric analysis is used to determine the migration of the prosthesis with respect to the bone.
Time frame: 24 months post-operatively
anterior-posterior translation patterns
Fluoroscopy was used to determine the anterior-posterior translation patterns of the femoral component with respect to the tibial component.
Time frame: 6 months post-operatively
Axial rotation patterns
Fluoroscopy was used to determine the axial rotation patterns of both the insert and the femoral component with respect to the tibial component
Time frame: 6 months post-operatively
Muscle activity
Bipolar surface EMG data of the flexor and extensor muscles is collected.
Time frame: 6 months post-operatively
Shear forces
A force plate is used to measure the ground reaction forces which can be used to calculate the shear forces.
Time frame: 6 months post-operatively
