Function, Pain, and Alignment Following Knee Replacement for the Treatment of Osteoarthritis
August 3, 2022 updated by: Monakshi Sawhney, North York General Hospital
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: Manual Adjusted Mechanical Alignment
Usual care:
|
Surgical technique for Total knee replacement will be standardized with a MicroPort prosthetic knee joint, patella replacement is optional based on the surgeon's assessment.
The participants will receive local anesthetic infiltration by the surgeon, and a similar anesthetic technique with spinal anesthesia using epidural morphine and single shot peripheral nerve blocks.
They will receive weight based antibiotics and tranexamic acid.
Participants will be randomized to one of three groups.
1)Manual adjusted mechanical knee alignment (usual care) involves the surgeon manually.
2) Robot assisted surgery will include using the ROSA© device from Zimmer©.
Robot assisted mechanical alignment aims for neutral alignment of the knee joint.
3) Robot assisted restricted kinematic alignment aims to place the knee joint closer to the participant's anatomical positioning.
