• A. it will improve sleep.
• B. it will help with appetite.
• C. it will assist with pain control.
• D. it is what the doctor ordered.

Answer: (C)

Moving the knee gently in small back-and-forth motions and allowing the leg to dangle after knee surgery helps control pain by promoting circulation, reducing swelling, and preventing stiffness. This gentle ROM decreases muscle guarding and joint stiffness that can intensify pain, so patients feel more comfortable and can move more easily as they recover. It’s not primarily about sleep or appetite, and it’s more than just following orders—the movement itself is a deliberate way to alleviate pain and improve joint function during early recovery.
