Early Migration in a High Congruent Rotating Platform Total Knee Prosthesis Design (ROCC)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
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).
