I have AVN and for the 3rd time I have to have a joint (knee/hip) replacements. I’m not really freaking out over it but am starting to get a little anxious. What would you do to get over the pre-surgery jitters? I’m so sick of this crap. (AVN is when the blood supply is, for some reason, cut off from the joint, the bones die and you’re left with bone on bone when it dies and collapses). It’s *very* painful!!! Any comments or people out there w/AVN would be very helpful, I’m sure. Thanks in advance.

my husband had many radiation treatments on his left leg and it is now weak and the bone won’t heal. he had a rod placed inside the bone because of a fracture. the surgeons don’t hold out much hope that it will heal. the last x-ray proved that statement to be true. It is not healing. i was wondering if the femur itself could be replaced along with a knee replacement.

I’ve had 3 joint replacements and now I have the same crunching in my ‘good’ knee!!! The crunching in it means the joint is bone on bone which will lead to another knee replacement. I see my orthopod next week and he will do xrays of it. The problem is that i’ve had 4 major surgeries since 2006 and i don’t think i can handle another one, nor do I think that my body can take more surgery. Do I wait till it totally craps out or do I go ahead with the surgery. My knee really hurts along with the crunching…Help anyone??? What would you do if you were faced with more surgery? Would you have it or what? I need advice….please!!!!

I had a knee/hip replacement last year. My knee (the latest sugery) still hurts like hell and I have avascular necrosis (dead bone) in my “good” knee but it’s not collapsing like the other knee did. Anyone else out there who has had this disease? Does it still hurt or not? Are you able to do all the things you used to do? Also, do you have to lift under 30# or not gain more than 30# after this surgery for the rest of your life as they say? Only serious answers please as this is a serious condition and anyone who has had this or knows someone with it would know that. Thanks a bunch in advance!
My joint replacements were because of AVN…avascular necrosis … when the blood supply doesn’t go to the bone for some reason and the bone dies. Yes, they had to make a special prosthesis for me as mine was pretty bad, but sometimes it REALLY hurts….I’m still limping on BOTH sides so it looks like I’m walking like frankenstein….if it didn’t hurt, it would be funny. Thanks for your answer

How Does Partial Knee Replacement Surgery Differ From Total Knee Replacement?
By Jeremy Reitherand Chris Al-Aswad

Arthritic knee joints may be repaired either partially or totally – known as partial knee replacement and total knee replacement. A partial knee replacement is also called unicompartmental or “UNI”. If the bone disease is restricted to the inner side of the knee (the ‘medial’ side), the surgeon will simply reshape those damaged surfaces. The repaired surfaces on that one side of the knee are then partially covered with a combination of metal and plastic bearings. For this reason, a UNI knee replacement is considered less invasive and can provide much shorter recovery times from the operation.

The primary limitation with the UNI procedure is that the surgery only works for bone that has not been too damaged by the arthritis. It also requires that the other (‘lateral’) side of the knee joint have healthy cartilage. The average age of UNI knee patients will therefore be a lot younger than those going for total knee replacement. This means that the UNI resurfacing option may only be a good choice for a small percentage of knee patients.

Generally speaking, UNI knee replacements are not performed on patients with arthritic damage on both sides of the knee. In more arthritic knees, there will be considerable erosion and deformity on both sides of the knee joint (as in ‘medial’ and ‘lateral’ sides). This will require more repair of the upper joint bone and the lower joint bone and sometimes also behind the knee cap. The UNI knee cannot accommodate such destructive changes in bone structure. Therefore in this case a surgeon will often opt to perform a total knee replacement – resurfacing bone with metal cap and tray.

Note that the most common method of fixing both implants to the bone is with bone cement. There are also options to provide for bony attachment and ingrowth onto the implants (bone ingrowth fixation). The final step is to insert a plastic cover onto the metal tray to act as the bearing knee for the knee joint.

There are other options to consider. The majority of knee patients do not get their patella replaced although this may become an option further down the road. There are also indications for knee operations that make use of smaller incisions (MIS: ‘minimally invasive surgery’) and use different kinds of instrumentation such as computer-assisted navigation (NAV).

Your doctor should explain to you which type of knee replacement surgery is best for you and why.

BoneSmart.org is a National Public-Awareness Campaign for Candidates of Hip Replacement Surgery and Knee Replacement Surgery. The BoneSmart(r) National Consumer Awareness Campaign’s mission is to raise patient awareness of the options available to persons diagnosed as a hip replacement or knee replacement candidates by providing an Internet portal for awareness of the latest advances in joint replacement materials, their longevity and suitability for various applications. With this information the potential patient may be better informed when discussing options with his or her surgeon.
