Which postoperative measure reduces pain and swelling in the first 24 hours after arthroscopic knee surgery?

• A. Remain on bedrest for the first 24 hr
• B. Keep the leg in a dependent position
• C. Apply ice to the affected area
• D. Begin active range of motion

Answer: (C)

Cryotherapy, or applying ice, is the most effective way to reduce both pain and swelling right after knee arthroscopy. Cold constricts blood vessels, which lessens fluid leakage into the joint (edema) and slows the inflammatory process. It also numbs nerve endings, lowering pain signals. For best effect, use a cold pack wrapped in a thin cloth for about 15–20 minutes at a time, several times in the first day, with breaks to protect the skin.

Other options don’t offer the same benefits in the immediate postoperative period. Staying in bedrest doesn’t directly reduce swelling and can lead to stiffness; keeping the leg dependent promotes venous pooling and edema; starting active movement too soon can increase pain and swelling. Ice directly targets the acute inflammatory response and provides rapid relief.
