After my right hip replacement on august 29th, my right leg was longer. My surgeon said this could happen, but it may correct itself. I felt I was limping because of the increased length. Physical therapy suggested an insert in my left shoe. That helped. 7 weeks post surgery and I don’t need the insert and I am walking without a limp.
In my case the discrepancy in leg length has corrected itself.
Perhaps in time your situation will improve.
