- Primary Outcome Measures
Name Time Method Patients with varus gonarthrosis have a higher postoperative AOFAS score after TKA with kinematic alignment compared with patients after TKA with mechanical alignment.
- Secondary Outcome Measures
Name Time Method - The AOFAS score correlates negatively with the measured angle between knee and OSG (FCDT, PTTA).<br>- Patients with varus gonarthrosis have a higher postoperative EFAS score after TKA with kinematic alignment compared to patients after TKA with mechanical alignment<br>- EFAS score correlates negatively with measured angle between knee and OSG (FCDT, PTTA)<br>- TKA with Kinematic Alignment reconstructs the joint line of the OSG closer to the original joint line than TKA with Mechanical Alignment.<br>- Kinematic Alignment leads to a more physiological and ergonomic force transmission in dynamic pedobarography compared to mechanical alignment<br>- Kinematic alignment leads to a more physiological gait pattern in motion analysis compared to mechanical alignement.<br>- Patients with incipient OSG osteoarthritis have less pain in the OSG after TKA with kinematic alignment compared to kinematic alignment<br>- JLO has an influence on the position of the OSG<br>
