Does elevation help with knees?!

Does elevation help with knees?

Just wondered if elevation will help with knees? i scraped myself just below the right knee. Cause just whenever I elevate my right legs and when I have to leave the bed its hurts bad..wondering if it hurts bad maybe I am not getting enough circulation in my right leg, where my injury on my knee is?

also, would cold compress on the knee injuty make it heal faster ?

The old saying "R.I.C.E." comes into play here: Rest, stay off of it as much as is possible. Ice; to remove swelling. Compression to reduce swelling and pain. Elevation: Also reduces swelling and relieves pain.
