Many total knee replacements are performed each year, but there is no clear recommendation regarding knee positioning following this surgery. While the surgical knee is usually positioned in a straight position immediately after surgery, there may be benefits of positioning it in a partially bent position. A trial will compare the outcomes of two groups of patients: a) those whose knees are positioned in a partially bent position for a few hours after surgery and b) those who receive usual care where the knee is most likely positioned in a straight position. The investigators are looking to see whether knee motion and pain differ for patients in the two groups.

Participant arm assignment will be concealed from the surgeon who will leave the operating room before the knee is positioned. The surgeon will also be the assessor of the primary 6-week knee total arc of motion endpoint. The patient and investigators assessing other endpoints will not be masked to the arm.
Participants in this arm will receive the knee flexion intervention.
Participants in this arm will receive usual care. No specific attention will be placed to knee positioning in the immediate period after surgery. However, the current usual practice in the health system is that the knee is positioned in extension.
