Hi, all,
Well, today I had a consultation with a revision sub-specialist about the issues I've been having with my knee, due to the laxity. These include swelling, some minor pain, clunking, irritation and the need to wear a fabric knee brace all the time. I apologize in advance, as this post may be a bit lengthy.
Some background rehash: My osteoarthritis was caused by a sports injury when I was a teen, where I tore 3 ligaments, and the ligaments were repaired. It was a serious injury. The knee was casted, and it has always been very loose since then.
I got plenty of answers from the revisionist. Very definitive answers.
Here is what the revision specialist said:
- Based on my previous injury, and the fact that my knee was so loose, the OS should have taken special care to balance the ligaments in my knee when doing the TKR. He did not do this.
- A posterior stabilized knee was not the correct choice for me. Some OS's will use these in an effort to negate the effects of loose ligaments. But in my case, this was not the correct approach. The revisionist would have used a PCL sparing knee, and balanced the ligaments.
- The OS should have used a quad sparing procedure. My quads were cut. Cutting the quads makes the situation with the loose ligaments even worse, and is a red flag in cases like mine, with loose ligaments.
- Doing a revision to just increase the size of the spacer (as my first OS suggested) will not help the problem of the loose ligaments. If anything, it will reduce my flex and extension, and create more stiffness. Not the correct approach. If I did this, I would likely be looking at a 3rd surgery.
- The stabilizing post on the plastic spacer of my posterior stabilized knee is taking a lot of stress, and is at risk for fracture. This could happen in one year, or several years, or not at all. I can reduce the risk by wearing a stabilizing hinged knee brace. I would need to be fitted for one.
- For a revision, it would be best to use a special Depuy stabilizing knee, based on the fact that I no longer have a PCL, and the looseness of my ligaments. Sorry, I forget the exact type of stabilizing knee he referred to (there was an acronym). By this point in time, I was in a state of shock, and probably had a deer in the headlights look.
- Plan A: I should return and get fitted for a stabilizing hinged knee brace. This will make me more comfortable, and should help with the laxity symptoms. But, it won't last forever, because....
- I have recurrent tendontitis and synovitis from the laxity in the knee. It is a viscous circle.
- Plan B: Depending on how long I can go with the knee brace, I will need a revision with the new special knee. Complete redo of the TKR, and another 12 weeks of rehab.
- He feels that my chances of a very good to excellent revision outcome are about 85%, based on all my history.
- The original OS was very conservative about how much bone he cut away for the tibial component, so I have plenty of bone to work with. The revision will not require a special tibial component with a long stem. That was the only good news.
- He knows the OS who did my original surgery. He is a general practice OS, he is not a knee replacement specialist, and he does not do many revisions.
So there you have it. When I left the office, I was in a state of shock, and I had to wait about 1/2 hr before I could drive home. I called my wife, and told her everything. I was very angry. I've calmed down a bit now.
I SO much wanted this TKR to work out. I'm very sad right now. I don't know if it's my fault for not getting a second opinion before moving ahead with the TKR from the first OS, or if it is the OS's fault for not properly balancing my ligaments and not using the correct knee and procedure? He knew how extremely loose my knee was prior to surgery. Probably both of us are at fault.
So now, I need to schedule an appointment with the revisionist to get the knee brace fitted. I will NEVER go see the first OS again! Then, I have to figure out how long before I have the revision done. I'm having a hard time bearing the thought of a revision, with another 2 months on disability leave from work, and 12 weeks to rehab the same knee. And what if the outcome is not good (if I fall into the 15%)? I'd like to put it off until I retire, in 7 years, but the plastic spacer stem may not hold up that long.
I'm going to tag a few folks who may be interested in this opinion. Comments are very welcome.
I'm trying to think of a new name for my thread. I was thinking "Botched TKR, now need a revision...". That may be a bit harsh. I'll wait a couple of days and try to calm down, then I'll try to think of one.
