I have the exact same problem! I came out of surgery in so much pain and even had to stay an extra day due to pain management. I kept telling them my leg was to long and it felt stretched. They just told me that it was impossible to come out of a TKR with a longer leg. One surgeon ever said that if they would have done that I would be in a lot of Pain because you can’t stretch tendons that long. I’m now 3 year post op and the pain is 24/7 and I am still taking oxy for the pain. Yep 3 year of oxy just do I can walk. I’m about ready to have them just remove the leg to stop this pain.
I’d love to hear how your sister is doing.
Thanks for listening
