Mom had both hers done over several years. She moaned and groaned about some of the pt but she is doing well since. Still mows her own yard including doing the trimming with push mower at 82.

Pulling for you Finney and “Momma Finney”!!!

 

 

 

 

 I am surprised that you did not rig up a chop saw to remove the worn “unit”, counterbore for the replacement, set a couple of Enerpacs, and glue it in with 11018MMR!!!!

I brought that up but it got shot down pretty fast!!!!!!

 There will be much pain with a knee replacement, they are hammered into place.  I have 1 of the hammers and it's practically a 1lb stainless dead blow. The newest tibia plates are all titanium forgings that are then machined to spec, on either a vertical mill or a horizontal one. They are now slightly angled for more mobility and flexibility. They are then glued to a poly piece that connects the bottom of the knee to the top.  Poly can be pre molded or bar stock depending on the knee. The pre molded only gets the bottom machined and the newest poly has vitamin e in it.   All poly is machined on horizontal mills.   Currently I no longer machine but write programs that check the parts to the blueprint.

Just got back from PT, made me cringe just watching.

What exercises are they having her do? Are they having her do her own at home? If so and she doesn’t want to, or do later have her break it up but to keep the joint moving for the workout even if a lighter workout is done, the pain and stiffness will subside and the big thing for me was once the swelling went down the exercises got easier even though they were more demanding, good luck, it sounds like she has a good kid helping her.

Have you done the regen joints? How much longer are they than the first time joints, I had both done the same day in ‘99, then I had the regen done in ‘12 and the regen literally kicked the devil out of me added to that was the self administered warfarin shot and I was not a happy boy til the swelling went down.

My grandpa got 1 knee replaced on June 21, he has been doing very well. Last week he got on the churches zero turn mower and mowed all the grass there- 3 hour job about. He hasn’t had much pain but in one spot where a nerve is still healing they think. The doctor thinks not much pain because his knees were so bad it kinda evens out with post surgery healing.

I had my left knee replaced in Jan 2000. Dr did what is called "noninvasive replacement" Not sure why they call it that as I had 32 staples to close the incision. With noninvasive they don't cut the muscles & knee cap is pushed to the side instead of removed as in normal need replacement. Recovery is suppose to be quicker. I didn't start physical therapy forb2 weeks but had lots of exercises to do. I was able to walk with a cane the day after surgery & was climbing stairs the next day. Three days after surgery could walk without the cane though I used it whennI was in public, people gave me more room when they saw the cane.

The physical therapist can be your best friend or your worst enemy. My knee replacement therapy wasn't nearly as had as the therapy after rotator cuff surgery. Do what they tell you to do but don't do too much.,Before replacement I couldn't walk over 100' without stopping to let the pain subside. Now I can walk as far as I want. I still have an unusual feeling on the lower, outer part of the knee, can't really explain the feeling, almost like it is too tight. Could be from have the lower part driven into to the bone like the poster who machined them said. Daughter had all surgery 14 years ago & says she has the same feeling.

Maybe me but the artifical knee seems a lot harder than my real knee. I sleep with a pillow between my knees, never did that before surgery.Im still reluctant to get down on the floor with that knee. Tried it once on a pillow & had a lot of discomfort. Dr says its a mental thing & I just need to get use to it.  Had a friend that is 82 that same Dr did same type replacement on last summer & he says he's never had those issues. Different people react different. I have a video of my surgery but haven't watched it, maybe some day. Dr says its pretty bloody.

"noninvasive replacement"

Same as my FIL's. His recovery was quite quick. I quiz him about it because I've had two surgeries on my right knee and it's become painful again. Xray two days ago shows little arthritis and still good spacing between bones so it's probably another soft tissue injury. Cortisone shot that day and if it doesn't improve, an MRI. It feels like another cartilage tear. Getting old isn't for wimps but beats a dirt nap.

I’ve held a few lower legs to the side, as the surgeon cut (Sawzall) and hammered (Hammer) the new parts in place.  Think that’s aggressive? You should see a Hip replacement.  Bigger hammer. 

And they don’t  compare to rotator cuff surgery. 

Joint replacement technology improves Every year.  Anything done 20, 10, even 5 years ago is now out dated. The new devices and procedures are different as will be the rate of exercise and progression. 

Listen to your Doctors and Therapists.

I've machined several thousand knees, it's amazing how advanced of a piece of engineering those are. 

Were they done “inframe”?  Machined on the patient?

 

Or were you implying that you were machining replacements?

Dang. I am in this same boat. Both my knees have been killing me the past several years, and I have just been ignoring it and carrying on, and basically taking over the counter pain killers, which haven’t done much good.

I’ve finally reached my breaking point. My job at work is being severely affected by the pain, as well as working around my home and property. Friday afternoon I went in to see an orthopedic knee and hip specialist. They took  X-Rays from various angles of both my knees. I was horrified to hear what the doc had to say. For one thing I found out I have osteoarthritis in my knees, and my knee cartilage is all but used up.

He injected cortisone steroid into both my knees and said that should bring me some relief. He wants to see how I do on that, and also told me that a gel shot in the  knees may also be an option if my pain persists. 

But he basically told me my knee joints are shot, and there’s no bringing them back. He said the cortisone shots may be needed every 4 to 6 months, but that will be just “kicking the can down the road” for maybe 1 to 2 years, if even that long, and then knee replacements will be needed. I was really bumming on the way home from my appointment and actually started tearing up over it as well. I guess I’ve been rough on my knees over the years, used and abused.

I hope the cortisone steroid shots bring me some relief for now. I’m fixing to retire anyway from my full time job, looks like now my last day will be Friday October 15. If I can even last that long. Currently debating whether to give my boss a 2 week notice or a 1 month quitting notice. I have been having a beeotch of a time climbing ladders, walking on uneven terrain, walking on slanted roof tops, or carrying heavy objects which puts even more weight and stress on my knees. I’m afraid  I’m going to have to tell my boss that I’m going to have to place some self imposed restrictions on myself going forward. Not good. Dam it all to h_ll. I am just sick over this.

well fooey rick, sorry to hear the used up knees.............prolonging the inevitable - our invincible mortality is humbling to say the least - if your boss is a good man and knows you have been a good employee i would think they know you will do your best regardless of your pain/circumstances. If not, you know what you need to do at that point. 

I hope you find some relief to carry on well and get to push it down the road a while longer

Welcome to the bad knee club Rick. I first tore a meniscus in my 20s taking a big step onto a wing carrying a heavy generator. It hurt then but I was able to carry on. Later that evening a couple of us in the flying club took two T34s to another airport for dinner. I slipped on clear ice, twisted the same knee and was totally incapacitated. My buddies tossed me on the floor in the back of a friends airplane and flew me back to Hanscom where I had recovered enough to drive home. A Dr. visit sent me to get a dye radio graph as that was before MRI existed. The doc drained my knee, inflated it with CO2, injected a dye, and took pictures while I was sinking my teeth into the stainless steel table. He kept saying "look at this" while I could barely keep from screaming. Interestingly, after that exercise I felt pretty good and while I could never really run much on the knee I never had it fixed. In those days there was no arthroscopy, they sliced your knee wide open and recovery was months. The other knee I tore twice and had arthroscopic surgery twice and recovery was quick but I'm pretty sure I've torn something again. 

Funny aside: Leaving the torment room and walking down the hall my knee was still inflated like a balloon and the gas was making subtle fart sounds shifting in my knee as I walked. I came across a couple of pretty candy stripes so stopped and pretended to look at pictures of past hospital administrators.

I wouldn't worry too much about knee replacement as every one I've spoken with who has had one or both reports pain free and as good or nearly as good as new. That included one of our pilots who had them both replaced (one at a time) a couple of years before he retired. Each time he was out for about a month. When he came back from the first replacement he said although the PT was a little tough he was quite ready to have the other done.
