I had to have my knee replacement revised as we were having problems with it. I had a lot of pain and now that seems to be fixed. But, I read that if you have a revision, you have a higher risk of breaking the thigh bone later. Is this true?

After a knee replacement, the femur, or thigh bone, can be fractured, either due to a trauma like a fall, or just from stress from the bone and the replacement. This does not happen often, but it does happen.

Researchers have found that of the people with these fractures, more patients had had revisions than first time surgery. Therefore, having had a revision, you do have a higher risk of a fracture.
