does anyone know how many knee replacements a person can have?

@amandaburnett That is so kind of you. Thank you so much. This Mayo Clinic Connect is such a great resource and I am so grateful!

Not sure if you will like my comments. I had a bad experience with my TKR so i did alternative therapy. From stem cells to PRP. I am bone on bone but have had great success with PRP. I do it yearly. I play golf, bike, garden etc. I am also 80. I did lose 15 pounds. I notice every year with PRP i am doing better. Arthritis seems to be ok and i do wear a special brace designed for active people. MY surgeon said i am 80 going on 70. I use Regenexx but i would say be careful who you see. A bunch of pirates out there. In other words do your homework.

To say one more thing PRP is great on arthritis. Takes a few days or a week to sit around. Better than surgery. Luck to you.

@katienaturegirl I read recently that although they thought initially that the robot-assisted surgery might have better results that now that it is in practice more often they are not finding that so, it's pretty much the same. I'm sure that's something that you can find if you google for it.

I am not 100% certain of this, others might know more than I do, but one of the minuses of it is that it is only available for certain brands of knee replacements. Personally, I'm all for custom made knees of course. Since they mimic your natural knee the recovery period is supposed to be shorter. Mine was very good but I never did reach the flex that I would have liked to have reached. I blame myself for that, I didn't do enough of the PT between sessions.

Thank you for you response. Curious why you had a bad TKR? Also are you doing the stem cell therapy in your other knee, or knee with TKR? My right knee is bone on bone. I ended up getting the hyaluronic acid injection last week. And to my surprise it started working that next day. I have no pain! I was told that the stem cell and PRP would not work for me, because I’m bone on bone. But you have definitely made me curious now! You sound like your more like 60 with how athletic you are. That is fantastic!

My TKR was one of pain and swelling. I would work out in the pool and swelling would happen. My knee is still swollen 7 years later. I have had tests to see if it came loose. I was told doing another TKR would only see a 10% improvement. So i have learned to live with it. I opted for stem cells and PRP as i did not want to go through another TKR where it may work or not. I
I also had PRP on my back for l4 and l5 and it has worked great. I noticed many NFL players are using it.
The question comes up about costs. After having a "free "tkr i will be happy to pay for stem cells and PRP. Many companies in our area are covering the costs. But i tell me people ,weigh the options and make a decision and live with it. If a peron as arthritis PRP seems to work well to eliminate the pain.

I've had 4 replacements on my right leg,and as a result of those tell and broke my femur same leg.It's been tough.

I have had two friends that both had amputations after TKR’s. They were both diabetics which is always a complicating factor, at least from what I have heard.

God bless you … I have had right knee done twice within the year… my first was too big …. I can definitely not see going through again even though the revision worked out great … I just would not put myself through again …. Takes so much I give you so much credit you must be very strong individual……I hope you find one day of relief than many more

I was hit by a drunk driver and had my left knee replaced at age 45. After rigorous PT and 2 MUAs I had a partial revision, another MUA (with 3 days in hospital on CPM with an epidural) and then a total revision (different surgeons). Then I went on to have arthroscopic surgery to clear scar tissue and another MUA.
Still stuck, implant loosening. Went to another surgeon experienced in multiple revisions 2 hours away and went on to have 2 more total revisions on that same knee a year apart. Now the joint is unstable (my latest surgeon retired) and it's being recommended that I have the spacer sized up but I am consulting with Mayo Clinic because each surgery ends up in the same place- contracture 80 degrees flexion and -7-10 degrees extension. I am now 51 and can barely walk with my good leg starting to show signs of wear and tear because it's doing all of the work. I am so exhausted and trying to maintain some hope that I can resume a somewhat normal life again. I have brought up amputation as an option and no one has said "no" or even been surprised I would consider it. But I see amputees able to do way more than I can and it no longer seems extreme. Generally it's considered with chronic infection and as a last resort but in my case, I am hoping for a better outcome on the knee but I have a life to live. Perhaps it's not the worst thing.

Long story to say- I've had multiple total and partial revisions on the same knee in the span of 6 years and no one has said another cannot be done. The posts are long and getting them out will not be without significant risk of catastrophic breakage but at my age, I will need it done again someday and likely more than once. So I am hoping the technology is advanced at that point and I will be able to retain my leg AND have better function.
