@ndreyer Welcome to Mayo Connect. Uneven leg length is a not uncommon result of hip replacement surgery. It is sometimes unavoidable if the joint was very damaged before replacement, and insertion of the properly shaped femur head and acetabular cup make the leg longer. One of my best friends is still adjusting, one year after her replacement (due to a broken femur head.) Now she only has issues if she is very tired.
Another thing to know is that most of us have some discrepancy in the lengths of our legs naturally or have developed them as joints wear, but our bodies have accommodated to them.
I have had five hip replacements and/or major revisions. Each one presented a new challenge as far as length. On my fourth surgery, the orthopedic surgeon tried to reduce the discrepancy between my legs by using a shorter stem, smaller ball and acetabular cup. That was a problem! The muscles and tendons were too long for the smaller implant and it dislocated.
Instead, intensive physical therapy and gait training taught my body to accommodate the difference. As I was adjusting, I used progressively thinner lifts in the shoe on the shorter leg, until I no longer needed any (took about 2 years.)
Have you talked to the physical therapist about gait training and using a heel lift in your shoe?
