I am 83 years old. 3-1/2 years ago I had a hip replacement, followed by a broken femur 6 weeks later. That left me with my leg about 2 inches shorter than the other leg. I was told about purchasing built up shoes, etc. I wore lifts in my shoes that helped, but did not make-up the length difference. The results left me with back problems and other aches and pains. Last fall I found out that I could have my leg made longer (NO JOKE). Four months ago the surgeon went back into my hip/femur and made my leg longer. It has made a world of difference in my attitude, being able to stand level. My balance is perfect.
I suggest that your sister see an orthopedic doctor and discuss the option of having her leg made longer.

My thoughts and prayers go out for your sister, I have Peripheral Neuropathy and had 4 TKRs on my left leg. Not my L leg is approx 3" shorter than the other. I went to a orthotic shoe co and they made a shoe approx 3" greater in height. I have also had shoes modified as a local leather co so getting it done is not difficult. But for me, it is very difficult to walk with the shorter leg on a built up shoe. My ankle tries to roll over and even when it doesn't I feel like I am balancing on high heel shoes! Also, all my life I have worn 9-1/2 EE but after the problems with my legs I was told I should wear size 11 EE! I feel like I am in clown shoes. I was unstable and tripping over things but I changed to a size 10EE and it made a huge difference. Don't always believe everything doctors tell you. You know more about your body than they do. Pay attention to what is happening and make sure what they say makes sense,
Best wishes for a Happy 4th of July!

Hi Mamie I am just curious how your sister is doing today, I am three years post knee replacement surgery and have major leg length discrepancy and still have major pain. By back pain is also getting worse. I know this is all due to my leg length discrepancy but nobody believes me. Has your sister found any relief?
Hope to hear from you,
Nick

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
Nick
