Experimentální: Knee Flexion
Participants in this arm will receive the knee flexion intervention.
|
Participants will receive knee flexion postoperatively following primary total knee arthroplasty.
The surgical knee will positioned at approximately 60° flexion using an abduction pillow as a jig underneath the knee during the immediate postoperative recovery period.
Positioning will occur following surgery while the participant is still in the operating room.
This is a soft construct and a noninvasive intervention.
A goniometer will be used to approximate 60° of flexion as closely as possible.
It is expected that the knee will be positioned for 2-4 postoperative hours until a physical therapist comes to mobilize the patient.
However, the duration may vary because of the pragmatic context.
There is no minimum or maximum positioning time that would make the intervention duration ineligible.

|
Aktivní komparátor: Usual Care
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.

|---|---|---|
|
Knee Passive Total Arc of Motion
Časové okno: At 6 weeks after surgery
|
Passive total arc of motion will be evaluated through goniometric assessment of maximal passive knee flexion and passive knee extension.
Both measures will be recorded, but a single endpoint will be derived by subtracting available extension from available flexion.
|
At 6 weeks after surgery
|
|
Maximum Pain Intensity
Časové okno: At 7 days after surgery
|
Pain intensity will be evaluated via the patient-reported Numeric Rating Scale (NRS) for pain.
The rating is from 0 to 10, with a higher score indicating worse pain.
The worst (i.e., maximum) pain intensity will be used.

Knee Passive Total Arc of Motion
Časové okno: At 2.5 weeks, 3 months, 6 months, and 12 months after surgery
|
Passive total arc of motion will be evaluated through goniometric assessment of maximal passive knee flexion and passive knee extension.
Both measures will be recorded, but a single endpoint will be derived by subtracting available extension from available flexion.
|

|
|
Total Opioid Consumption
Časové okno: Postoperative days 0 through 14
|
Consumption of opioids standardized in oral morphine milligram equivalents based on medical records for in-hospital administration, prescriptions, and patient report for at-home consumption.
Consumption will be summed across days, with higher numbers indicating greater opioid consumption.
|
Postoperative days 0 through 14

|
Knee Injury and Osteoarthritis Outcome Score for Joint Replacement
Časové okno: At 6 weeks, 3 months, 6 months, and 12 months after surgery
|
The Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR) is a patient-reported measure of knee health (i.e., pain and function).
Scores range from 0 to 100, with higher scores indicating better health.
|
At 6 weeks, 3 months, 6 months, and 12 months after surgery
|
|
Veterans RAND 12-item Health Survey
Časové okno: At 6 weeks, 3 months, 6 months, and 12 months after surgery
|
The Veterans RAND 12-item Health Survey (VR-12) is a patient-reported measure of global physical and mental health.
It provides a physical component summary score and a mental component summary score.
These are T-scores with a mean of 50, and higher scores indicate better health.
|
At 6 weeks, 3 months, 6 months, and 12 months after surgery
|
|
Goodman Satisfaction Score
Časové okno: 12 months after surgery
|
The Goodman Satisfaction Score assesses patient satisfaction with total hip or knee arthroplasty outcomes.
Scores range from 0 to 100, with higher scores indicating greater satisfaction.
