I'm having the same problem. I only have 60 degrees ROM. My right is twice the size of my left I can only barely work 2 hours a day. I have no quality of life. Not able to do anything physical. Waiting for my pool to open. Only relief I get. I think I'm allergic to the surgical cement. It was like pulling teeth to get the info and name of the cement but got it. Scheduled at large trauma center hospital here in Milwaukee with top dermatologist to be tested to metal, nickle and all the compounds in the cement. Bad part is that this my revision already had a replacement w yrs ago when the cement was first put in my knee. Have never had any relief since replacement dec 2022. Then manipulation, scope a d revision last Sept. That's when they put back into twice as much cement. My doctor used top of the line nickle free replacement for my revision incase I had a nickle allergy.....never tested me for anything! It's mentally so frustrating going from somebody that was active 100% of the time and had a job that required me to be on my feet 90% of the time to being 90% disabled. I can't walk up a curb or get in my car safely, I've fallen 3 times on the ice. It's been a living nightmare. I'm sorry for such a long chat but it gives me support to know someone else understands what I'm going through. Please feel free to stay in touch .

I've attached a picture from a few days ago.
