Conditions
Brief summary
This study is a prospective, randomized, longitudinal study of the clinical and biomechanical outcomes of osteoarthritis patients treated by two different alignment philosophies for total knee replacement. All patients will be treated with the same knee system, implanted using nagivated assisted technology. We hypothosize that Inverse Kinematic alignment (iKA) will result in better Oxford Knee score (OKS) and satisfaction visual analogue scale (VAS) score compared to mechanical alignment (MA).
Interventions
Patients will receive their total knee replacement according to inverse kinematic alignment principles. The implant will be aligned using computer navigated surgery.
Kinematic principles position the knee replacement in a way that respects the natural joint line and rotational axis of the knee. Each surgery will take approximately 2 hours. The surgeons performing the surgeries have a be fellowship trained in knee arthroplasty. Post-operative alignment will be confirmed using CT and long-leg rad
