@gh120 @heyjoe415, I do think each surgeon may have their own recommendations for a good recovery. I also had always heard that icing is needed to reduce the swelling along with elevating the leg. I've had more than one Mayo surgeon emphasize that point with me. It definitely helped reduce the swelling with my TKR.

From the American Academy of Orthopedic Surgeons
" Swelling
You may have moderate to severe swelling in the first few days or weeks after surgery. You may have mild to moderate swelling for about 3 to 6 months after surgery.

To reduce swelling, elevate your leg slightly and apply ice. Wearing compression stockings may also help reduce swelling. Notify your doctor if you experience new or severe swelling, since this may be the warning sign of a blood clot."
