How Long Does a Hip Replacement Last?

Search this question and you get a number. Fifteen years. Twenty years. Ninety percent still working at ten.

Those numbers are real. They come from joint registries, which are enormous databases tracking hundreds of thousands of replacements. They are the best information anybody has.

They also could not be less useful to the person actually asking, and it took me years to understand why.

The averages describe a population you may not belong to

The typical hip replacement patient is in their late sixties. The registry average is built mostly from those people, living those lives.

I got mine at nineteen.

So when I asked how long it would last, the honest answer was that nobody knew, because there was almost nobody like me in the data to compare against. I wasn't a data point in the average. I was outside it.

If you're young, or an athlete, or planning to work a physical job for another thirty years, you are outside it too. The number you found is describing somebody else's hip in somebody else's body doing somebody else's week.

That cuts both directions, and this is the part almost nobody says out loud. Being outside the average doesn't only mean worse. It can mean better. Younger patients heal faster, build more muscle around the joint, and hold that muscle longer. Whether the activity or the strength wins out is not something an average can tell you.

My data point

I've had a total hip replacement since I was nineteen. Chromium cobalt, left side, after Legg-Calvé-Perthes wrecked the joint starting when I was seven.

Twenty-one years later, I'm forty-one and I still pitch. Real innings — a hundred pitches in Florida summer heat.

In between, I pitched seven professional seasons on it. The Frontier League, the Golden Baseball League, the Mexican League, the Can-Am, the Czech Extraliga. I threw a no-hitter on it. I threw more than five hundred strikeouts on it.

That is one person. I want to be direct about that, because the internet is full of people generalizing from a sample size of themselves. I am a single data point, not evidence. What I can tell you is that I represent the far end of what a replaced hip has been asked to absorb, and it's still here.

What I think actually mattered

I am not a surgeon and this is not a prescription. It's what twenty-one years of paying attention has taught me about my own joint.

The muscle around it does the work, or the joint does. This is the whole thing, and it's the part I'd underline if I could only keep one sentence. A hip replacement is a mechanical bearing. Every rep of load that your glutes, hamstrings, and core fail to absorb gets absorbed by hardware instead. Weak hips don't protect the implant by staying still. They just hand it more of the job.

Range of motion is not optional. Six months after surgery I was throwing off a mound, and I had roughly half again the range of motion I'd had before the operation — because the arthritic joint had been locking up for a decade. I kept that range with yoga, and I've kept doing it for twenty-one years. The years I let it slip are the years I felt worse.

I rehabbed like it was the job, because it was. A book called Core Performance by Mark Verstegen taught me most of what I know about maintaining a body. Not a hip protocol — a body. That distinction turned out to matter.

Bodyweight is load, every step, forever. Nobody enjoys hearing it. It's still true, and it's the one variable most people can move.

The part I don't know

I don't know how much longer mine lasts.

That's not modesty, it's the actual situation. Revision surgery is a real thing that happens to real people, and twenty-one years in, it is a legitimate possibility in my future rather than an abstraction. If it comes, it comes. I'll have gotten twenty-plus years and a professional career out of a joint that was supposed to end the career before it started.

What I won't do is pretend I beat something. I got a good implant, a good surgeon, and I did the maintenance for two decades. Some of the rest is luck, and anyone who tells you otherwise is selling something.

What to actually ask your surgeon

The internet cannot answer your version of this question. Your surgeon can get closer. Most people don't ask well, so:

• What bearing surface am I getting, and why that one for me? The materials that rub together are the wear surface. It's the most direct answer to "how long" that exists.
• Given my age and what I want to do, what's your honest expectation for revision? Not the registry number — their expectation for you.
• What activities do you actually want me to avoid, and which ones are you telling me to avoid because you tell everyone? These are different lists. Find out which is which.
• What does the strength work look like at year five, not week five? Almost all rehab conversation covers the first three months. The other twenty years are where the implant is won or lost.
• If I need a revision someday, does anything I do now make that harder? Worth knowing before, not after.

If you're deciding right now

The question underneath "how long does it last" is usually not really about the hardware. It's am I going to get my life back, and for how long.

I can't tell you your number. What I can tell you is that at nineteen I was told a lot about what this joint would prevent, and then I spent seven years being paid to do the thing it was supposed to prevent, and I'm still doing a version of it at forty-one.

That isn't a promise. It's just proof that the ceiling people describe to you is an average, and you are not an average.

If you're facing one of these and want to talk to somebody who has lived on one rather than read about them, that's what I do.
