Uitkomstmaten
Primaire uitkomstmaten
Pre operative approved planning for the femur and tibia component were compared with the post operative achieved alignment of each component on radiographs. <br>
Biomechanical limb alignment and implant position were measured with a calibrated protocol on digital images on a PACS system [Boonen et al 2012,Boonen et al 2013]. Biomechanical axis (HKA: Hip-Knee-Ankle angle) was evaluated on standardized 1-year postoperative coronal full leg standing radiographs. Varus/ valgus position of the femur (FFC) and tibia (FTC) components perpendicular to the HKA angle were measured on the same coronal radiographs.
