Twenty-One Years on a Chromium Cobalt Hip

People say titanium. Mine is chromium cobalt — a cobalt-chrome alloy, which is one of the standard bearing materials in hip replacement and has been for a long time.

I mention it because the material is the part everyone gets wrong and the part nobody should care about, and because it's the only genuinely technical thing in this post. What follows is not engineering. It's twenty-one years of one man paying close attention to one joint.

The number

I had the replacement on 25 July 2005, at nineteen.

At the time, the figure I was given for how long one lasts was fifteen to twenty years, and the whole argument against operating on a nineteen-year-old was that I'd burn through it and need a revision in my thirties.

It's 2026. I'm forty-one. I have not had a revision, and I throw about a hundred pitches a game in Florida summer heat.

I want to be careful with that fact, because it is one person's outcome and not a promise. Implants and techniques have changed enormously since 2005; my surgeon, my anatomy and my luck are not yours. But it's true, and I'd have wanted to hear it at nineteen.

The thing that mattered most, by a distance

If you take one sentence from this: strength around the joint is the whole game.

Not mobility. Not supplements. Not any specific exercise. The muscle surrounding a replaced hip is what determines how much load reaches the hardware. Strong support means the joint absorbs less. Weak support means the implant takes everything, every step, for decades.

Twenty-one years in, that's the only variable I'm confident about. It's also the least interesting answer, which is why nobody sells it to you.

What I do, honestly

Lifting, continuously. Not in phases, not seasonally. The years I've been strongest are the years the hip has been quietest.

Yoga. I found it during rehab at twenty and it did more than any protocol I was given. Not as stretching — as relearning how the joint moved and how aware I was of it. Every stretch of my life where I've had a consistent practice, everything else has fallen into line.

Warm-up, without exception. More on this below.

Bodywork. I see a chiropractor — he's on my list of the people who got me here, which tells you what I think of it — and I use stretch therapy. When you have one joint that can't be replaced casually, the joints around it doing their share stops being optional.

Attention. This is the one I'd underline after strength. Twenty-one years in, I know what this hip feels like on an ordinary Tuesday. So I notice immediately on the day it doesn't. That awareness isn't caution — it's the reason I'm still going.

What changed

Warm-up stopped being optional. In my twenties I could skip it and get away with it. I cannot now, and the price of relearning that is a bad week rather than a bad rep.

I got better at knowing, and worse at recovering. Those trade against each other more evenly than you'd think. I'm not as good as I was at twenty-five. I'm considerably better at knowing what my body needs, and it turns out that matters more over a long enough run.

The lessons compound. That's the honest description of ageing with a replaced joint. Twenty-one years of paying attention to one hip has made me more durable than I was at twenty-two with two original ones and no idea what I was doing.

What I stopped

Distance running. I move constantly and I sprint in the course of playing, but I have never taken up running for its own sake. Repetitive impact is the mechanism people worry about with wear, and that's a trade I chose not to make. If I wanted to, I'd have a long conversation with a surgeon first.

Assuming. I've never had a season where I ignored the joint. The people I've watched get into trouble aren't the ones who did too much — they're the ones who did too much without noticing.

What I don't know

A short list, because a post like this usually pretends otherwise.

I don't know how much of this is the work and how much is luck, my anatomy, or a good surgeon in 2005.

I don't know how long it has left. Nobody does.

I don't know whether pitching professionally for seven years on it cost me time at the back end. It might have. I'd make the same trade again, but I'd be lying if I said I knew the bill.

And I don't know whether any of this transfers. Twenty-one years is a long time and a sample of one.

The part I'd actually give someone

I'm not a doctor, a surgeon or a physical therapist. I can't clear you for anything and I haven't seen your imaging.

What I have is this: at nineteen I was handed a projection built on patients whose goal was to walk without pain, and I've spent twenty-one years finding out the projection wasn't a ceiling — it was a description of the average.

Get strong around it. Warm up every time. Learn what it feels like on a normal day so you notice the abnormal one. Say your actual sport out loud to your surgeon instead of asking whether you can "stay active."

Then go and find out where your own ceiling is. Mine wasn't where they told me it would be.
