I had total knee replacement surgery and went to the rehab for a week, I have been home since thursday and it still hurts! I am taking pain medicine, but it just don't feel better. How long will this go on? Should I call a doctor? Do you know a good website that will tell me? Thanks for any info!How long till my knee feels better after total knee replacement surgery?Seems like a week is not enough of therapy for a knee replacement. Did they tell you yo continue these procedures at home? My brother had his knees done and I believe it was almost a month for him. He even used crutches for a week. Therapy has to keep bending your knee until it reaches a certain level of bending. Did you achieve that? If not, you need to go back to therapy. I would call the Surgeon who did it and inform him/her of how you feel. You might try medlineplus medical website and click on health topics. You could also try the mayoclinic.com. Wishing for you the very best young lady and good luck with that knee replacement.How long till my knee feels better after total knee replacement surgery?I would suggest going on to the website and doing some research after you consult with your doctor. Possibly, your doctor can steer you to some really good websites. I heard webmd.com is good.
