Since hip replacements make one leg shorter , how do you prevent walking from left to right?

Shoes with differing sole thickness.

Where on earth would I purchase shoes that are so different?

The difference shouldn’t be huge. Try adding 1 or 2 aftermarket shoe inserts to the shorter leg shoe…

Also. There is a custom shoe place in my city. There may be one where you live. The prices are not much more than normal.

The doctor should be able to help you out with this issue.

Depends on his age I guess. My F-I-L had both done at the same time so I guess they both shortened the same amount.
He exercised religiously to recuperate…........for a week and then quit and started just living again. He never got back to the way he was but he did mover fairly well. A little stiff starting up in the morning but seemed to loosen up as the day progressed. He was a very active man all his life however.

@Aster Your husband has really had some struggles with his health.

Please help him look into some orthotics. It’s not uncommon to have one leg shorter than the other – many people are born that way – and the adjustment should be simple and inexpensive.

With a new hip, he should be doing so much more than watching TV and napping. I hope he can reclaim more quality of life.

I have a natural leg length discrepancy and I have a lift that fits in my shoe, made by a doctor.

I’m sorry you both are going through this. It must be so frustrating.
Time, shoe lifts and exercise will help.

While you are waiting please enjoy this short video by NPR entitled Why We Can’t Walk Straight .
Synopsis: “Try as you might, you can’t walk in a straight line without a visible guide point, like the Sun or a star. You might think you’re walking straight, but as NPR’s Robert Krulwich reports, a map of your route would reveal you are doomed to walk in circles.”

So, we all walk in circles. But, some people’s circles are tighter than other’s.

I bought him a set of lifts for his shoe but he said, “it’s too uncomfortable.” He likes the shoes a lot but they’re very heavy leather with velcro closures. He needs lightweight shoes, in my opinion. But he can’t do laces.
He is quite difficult when it comes to listening to me or to doctors. Sadly, I know he’ll change when it’s too late.

@Aster the shoes can take some getting used to, maybe he’ll come around. It sounds like a lot of adjustments all at once, which can be hard for anyone.
