Hello, I am a 36 yr old female with avascular necrosis in several joints in my body. I have received a total left knee replacement at 33 yrs old. I also had a core decompression on my left hip at age 31. I was recently diagnosed with avn in my right talus. Ortho doc said it was significant avn but has not yet collapsed. He said that all he could do is a bone fusion. However for the next 2 months he wants me to wear a brace to see if that helps. I m just wondering is this is all that can be done. To me a bone fusion seems pretty drastic and if there are any other options out there I would like to know about them. Thank you
