Revision Hip Replacement: When a Hip Is Redone, and What It Involves

A revision hip replacement is a second operation that removes a worn, loose, dislocating, or infected artificial hip and replaces some or all of its parts. It is the word that hovered over my own decision more than any other, because at 58 I knew I might be young enough to face one. So I went and learned what it actually means, rather than letting it sit in my head as a vague threat.

The short version is that a revision is not a failure of you or your surgeon. It is the planned-for fact that a mechanical joint, like anything that bears your weight thousands of times a day, has a working life. What follows is what gets revised, why, and how the second operation genuinely differs from the first.

What “revision” actually means

Revision is an umbrella word, and that is the first thing worth knowing. It covers everything from a small repair to a near-complete rebuild. A first hip replacement (primary total hip arthroplasty) fits a stem in the thigh bone, a cup in the pelvis, and a ball-and-liner bearing between them. A revision might swap just one of those pieces, or all of them.

At the simple end, the surgeon exchanges only the plastic or ceramic liner that has worn, leaving the well-fixed metal parts in place. At the complex end, a component that bone has grown firmly onto has to be carefully removed, often taking some bone with it, and the lost bone is rebuilt with graft or specialist parts before new components go in ¹. Knowing which end of that range you are facing changes almost everything about what to expect, so it is the first question I would ask.

Why a hip gets revised

A hip is revised when something has gone wrong that cannot be fixed by leaving it alone. The main reasons sort into a handful of groups.

Wear and loosening over many years is the classic one: the bearing surfaces wear, or the implant slowly works loose from the bone, and the joint becomes painful again. This is a decades-long process and the reason follow-up X-rays continue even when you feel well, because loosening often shows on a scan before you feel it. Repeated dislocation, where the ball keeps slipping out of the socket, is another, and it points to a positioning or soft-tissue problem that a revision can correct. Deep infection of the joint is a serious, separate reason that often needs its own staged approach. Less commonly, a fracture of the bone around the implant, or specific wear-related reactions to certain older metal-on-metal bearings, lead to revision too.

I cover the early problems, the ones that tend to appear in the first weeks and months rather than years later, in hip replacement risks and complications. Revision is mostly, though not only, about the long-term ones.

How often it is actually needed

Revision is uncommon, and the numbers helped me more than any reassurance did. In large national joint registries and pooled studies, around 90 to 95 percent of hip replacements are still in place at 10 years, and about 6 to 8 in 10 are still working at 25 years ². Turned around, that means roughly 1 in 20 has been revised by the 10-year mark, and the majority of people never need a second operation at all.

The figure that mattered for me personally was age. The younger and more active you are when you have the first hip done, the more years the implant has to survive, so the higher your lifetime chance of a revision. That is not a reason to delay surgery when you genuinely need it, but it is exactly why a younger patient should have the “you may need this done again one day” conversation early and unhurried, rather than discovering it later. If you want the longevity side in full, I wrote how long does a hip replacement last for that.

How the operation differs from the first

A revision is usually a bigger undertaking than the original, and it helps to know that going in rather than expecting a repeat of the first day. The surgeon has to get past scar tissue from before, remove components that bone has often grown onto without taking more bone than necessary, and only then fit the new parts. That extra work means the operation is frequently longer and the planning more detailed ¹.

Because of that, revision is often done by surgeons who do a lot of them, with specialist implants on hand: longer stems, augments, and reinforcement parts that grip bone in different places when the usual surfaces are worn. The anaesthetic, the blood-clot precautions, and the surgical safety checklist are the same careful framework as any major operation ³. What changes is the variability. Two people both having “a revision” can have very different operations, which is why a generic timeline is less useful here than for a first replacement.

Recovery, honestly

Recovery from a revision varies more than from a first hip, and the honest answer is that it tracks the size of the operation. A straightforward liner exchange can recover almost like a primary replacement, with many people up and walking with aids within a day or two. A complex reconstruction, where bone has been rebuilt, may come with restrictions on how much weight you can put through the leg for a period of weeks, and the whole arc back to normal daily life can run longer, often in the region of 3 to 6 months and sometimes more.

The emotional side is its own thing. Going through it a second time, when you remember the first recovery, can feel harder before it feels better, and I think it is fair to name that rather than pretend a revision is just round two. The flip side is that you already know the drill: the precautions, the physiotherapy, the slow daily gains. For deep infection specifically, recovery often involves more than one stage, because the implant may be removed and the joint treated with antibiotics over weeks before a new hip is fitted. The evidence comparing single-stage and two-stage approaches for an infected joint is still developing, and the right choice depends on your particular infection and health ⁴.

What a revision is likely to give you

A well-done revision can last many years, and for most people who need one it is the last hip operation they have. On average the survival of revision implants is a little below that of a first replacement, and the chance of needing a further revision is somewhat higher, which is precisely why surgeons work so hard to identify the true reason for the original failure before operating ¹. Fixing the wrong problem is the thing that leads to repeat operations.

I will end where the word started for me. Revision sounded, before I understood it, like the catastrophe that undid everything. It is not that. It is a well-established operation that exists so that a worn-out hip can be made to work again, and the fact that it is there is part of why having the first one was the right decision and not a gamble. If you are still earlier in the process and weighing whether to have a hip replaced at all, signs it is time for a hip replacement is the more useful place to begin.
