About
There are many factors that can influence patient satisfaction and patient related outcomes following total knee replacement including the surgical alignment of the joint components. Historically, total knee replacements have been performed with an aim aiming to achieve neutral alignment or a mechanical weight axis in the lower extremity . However, only 0.1 % of the population have a pre-surgical anatomical neutral alignment, and therefore the constitutional anatomy of the patient is neglected. There is a growing trend to return patients back their anatomical constitutional alignment after a knee replacement, referred to as Kinematic Alignment using robotics. The aim of this randomized controlled trial is to examine how mechanical alignment and kinematic alignment impacts function, pain, mood and fatigue following TKR for the treatment of osteoarthritis. Outcomes will be measured at 6 week, 6 months, 1 year and 2 years after surgery.
