Hi @roknrol101 - First, welcome to Connect! I'm glad you found this group. Great people here with plenty of TKR experience. I have had both knees replaced - two years apart. My most recent one was January of this year. I definitely think physical therapy could help you regain ROM. Anytime we exercise and work out our joints and muscles, it helps increase flexibility and doing it under the direction of a knowledgeable therapist should just add to the benefit. At the same time, I'm thinking that after 5 years, you might want to schedule a re-check with you orthopedic surgeon just to ensure that there aren't other contributing factors like scar tissue, etc. When you say limited ROM and swelling, can you share some specifics... how much ROM? a little swelling occasionally or lots of swelling every day? Also, what do you think about having the OS do a re-check?
