In postoperative care for total knee replacement, which resting position is typically maintained?

• A. Knee in flexion
• B. Knee in extension
• C. Hip in internal rotation
• D. Ankle plantar flexion

Answer: (B)

After total knee replacement, the resting position is keeping the knee in extension. Maintaining the knee straight helps prevent flexion contracture, protects the new joint during the early healing period, and supports easier progress with ROM exercises later. Resting with the knee flexed can lead to stiffness and scar tissue formation, making it harder to regain full motion. Positions involving the hip rotating inward or the ankle pointed downward don’t support knee healing and can cause discomfort or misalignment, so they’re not the typical resting choice.
