Knee Revision surgery and leg length discrepancy

Posted by playfairy @playfairy, Oct 16, 2022

Has anyone had a knee revison or replacement surgery and after the leg is longer than the other leg which had already been replaced?

I found this after a search:

"Generally speaking, the length of your leg is governed by the medial and lateral collateral ligaments – the MCL and LCL. These are the large strap-like ligaments that run down the inside and outside of the knee. As a knee replacement doesn’t affect those ligaments, leg length remains unchanged."

Here is the link, with more information.

FWIW, I had both knees replaced this year and haven't noticed a leg-length disparity. I did wonder about it before surgery but never asked. I suggest you confirm with your surgeon.

All the best,

Joe

I had my right hip replaced 7 weeks ago and my right leg is definitely longer than my left. So much so that my PT suggested 1/4" lifts in my left shoe to start. My surgeon stated that my brain would eventually correct this problem, but so far lifts are helping.
