DawnMarie, My knee was really swollen after my injury and got worse after surgery. I did PT and ice packs, etc. to get very little results. Until a nurse told me to fill little dixie cups with water half full and freeze, ever 1 1/2 hours put your leg flat on the couch with a towel underneath and gently rub the ice cube from dixie cup all around the knee (front, back and sides). It is super cold but worked 100% better than ice packs. Doing this religiously for 4 weeks helped much better than PT. But for you doing this with the PT should put you on your way to an extra speedy recovery.
