Kinematic Analysis of a PS, FB Primary Total Knee Arthroplasty (ATTUNE Knee System) Using Dynamic RSA

"The patient will undergo primary Total Knee ArthroplastY use ATTUNE Knee System. During surgery a navigation system will be used to record preoperative joint kinematics under different tests. During the test the 6 degrees of freedom (DOF) of the joint will be computed and shown to the surgeon; these are the femoral rotation and translation pattern against flexion ranges. Navigation system will be also used to monitor the implant positioning and possible surgical bias. Dynamic RSA will be used to analyze the in vivo kinematics of the prosthesis at 6 months follow-up.~The above mentioned motion tests will be performed 3 times. The first 2 will be executed to gain comfort with the experimental set-up with no X-ray exposure. During the last data is collected."
