Total Knee Anthroplasty Clinical Trial
Official title:
Kinematics Analysis: Comparison Between the Cruciate Retaining, Fixed Bearing Primary Total Knee Arthroplasty ATTUNE TM Knee System and the Fixed Bearing PFC Sigma Curved Total Knee Arthroplasty
The primary objective is to quantify and compare the three-dimensional kinematics of the
cruciate retaining (CR), fixed bearing ATTUNETM TKA to the kinematics of the PFC Sigma Curved
CR Fixed Bearing TKA (both DePuy Synthes, Johnson and Johnson) during daily activities.
The secondary objective is to describe the kinematics in terms of range of motion, patterns
of anterior-posterior motion of the nearest medial and lateral points ("posterior femoral
rollback") and tibio-femoral internal/external rotation as well as the kinetics during daily
activities, such as level gait, a deep knee bend (only ATTUNETM subjects), sitting down onto
a chair, standing up from a chair and stair descent by means of video-fluoroscopy.
Furthermore, the encoded data will be handed over to DePuy Synthes (Johnson and Johnson) and
to the Center for Orthopaedic Engineering of the University of Denver, where it will be used
within a musculoskeletal model with the aim of simulating tibiofemoral contact mechanics and
changes in the musculoskeletal system due to the TKA.
