The surgery went well and the X-rays look good.
Your surgeon is pleased, your incision healed months ago, and the arthritis pain that drove you to the operating table in the first place is genuinely gone.
And you’re still limping.
If that’s you, two things are worth knowing right away.
First, this is common — far more common than the recovery pamphlets probably suggest.
Second, in most cases it isn’t a sign that something went wrong with the joint – it’s usually a sign that something around the joint hasn’t caught up yet.
As a home health physical therapist, I see this all the time and most patients are told the limp will eventually go away on its own.
And sometimes it does.
But the hip replacement fixed the joint surface, it didn’t rebuild the muscles that hold your pelvis level (and it didn’t erase the walking habit you built up over the years the hip was hurting).
But no worries, both of those are fixable (but they’re fixed with work, not with time).
First: How Long Is a Limp Supposed to Last?
Timelines vary with your age, your surgical approach, how long you were limping beforehand, and how much rehab you actually did.
Plus, everyone responds differently to surgery, so it’s challenging to compare yourself to others.
Broadly, though:
| Time since surgery | What’s typical |
|---|---|
| 0–6 weeks | A clear limp, usually with a walker or cane. Entirely expected |
| 6 weeks–3 months | Steadily improving. Cane use tapering. Limp noticeable but shrinking |
| 3–6 months | Most people are walking without an obvious limp on level ground |
| 6+ months | A persistent limp is worth actively addressing, not waiting out |
A persistent limp doesn’t automatically mean your hip replacement failed. Common contributors include hip-abductor weakness, an old walking pattern, stiffness, or a difference in leg length. If the limp isn’t improving, a PT gait assessment can help identify what’s actually driving it.
The common guidance is to raise it with your medical team if a limp is still there past the three-month mark.
That’s reasonable advice, and it’s also where a lot of people fall through a gap — they’ve been discharged from physical therapy, their surgeon’s follow-up is a quick X-ray and a handshake, and nobody is watching them walk down a hallway.
If you’re past six months and still limping, that’s not something to keep waiting on. It’s also not usually a surgical problem.
Why the Limp Persists
Four reasons account for most of it. They overlap, and plenty of people have more than one.
1. The muscles on the side of your hip are weak
This is the big one.
Every step you take is a brief stand on one leg.
Around 40% of the walking cycle is spent balanced on a single limb, and during that moment a group of muscles on the outside of the standing hip —the hip abductors, mainly the gluteus medius — has to hold your pelvis level against gravity.
Those muscles take a beating around a hip replacement, from several directions at once:
- They were likely already weak before surgery. If you limped for two years while the arthritis got worse, they’d been under-used for two years.
- The surgery itself affects them. Depending on the approach, the abductors may be cut, detached and repaired, retracted hard, or simply disturbed. All of it costs strength.
- The mechanics can change. Where the new components sit affects how much leverage those muscles have. Research on limping after hip replacement points to relative insufficiency of the abductors — sometimes related to the position of the greater trochanter and the center of the prosthesis — as a direct mechanical cause (review of hip biomechanics and limping).
- Post-op precautions can limit early loading. Necessary, but the muscles don’t get worked during the period they most need it.
When those muscles can’t hold the pelvis level, one of two things happens: your pelvis dips on the swinging side, or your upper body tips over the operated leg to compensate.
Either produces a visible limp, and neither hurts.
That mechanism is covered in more detail in limping with no pain, including how to tell which side is actually weak — it’s the side you’re standing on, which catches almost everyone out.
2. You’re still walking the way you walked before surgery
This one gets overlooked constantly, and it’s the reason a technically perfect operation can leave you limping.
If your hip hurt for two or three years, you spent those years learning to walk in a way that hurt less.
Shorter step on that side, less time on that leg, a slight lean, toes turned out, etc.
Your body got really used to walking like that and habits can be tough to break.
Then a surgeon removed the reason for it — and left the habit completely intact.
Nobody’s motor pattern updates itself just because the pain stopped.
The old walk has to be deliberately unlearned and a new one deliberately practiced. Strengthening alone won’t do it, which is why some people get measurably stronger and still limp.
3. Your legs may not be exactly the same length
Leg length differences after hip replacement are common, usually small, and often the difference between an old shortening being corrected and a new one appearing.
One review of hip arthroplasty describes leg length inequality as the leading culprit behind persistent limp, while also making a point patients are rarely told: geometrically equal leg lengths aren’t achievable in every case, because leg length and joint stability are linked, and surgeons sometimes have to prioritize a stable hip over a perfectly matched one.
That’s worth sitting with.
A small length difference isn’t necessarily an error — it can be a deliberate trade for a hip that won’t dislocate.
It’s also worth knowing that a leg can feel longer or shorter than it measures – I hear this one from patients all the time.
After years of a shortened arthritic hip, a corrected leg often feels too long for a while, even when both legs are even.
That sensation usually settles over several months as your body recalibrates.
If a real difference is confirmed and it’s causing problems, a shoe lift is a simple fix.
That’s a conversation with your surgeon or a physical therapist who can actually measure you — not something to self-diagnose.
And don’t worry, measuring leg length difference is easy and painless.
4. Stiffness and soft tissue
Scar tissue, a tight hip flexor from months of sitting, restricted extension, and general soft-tissue guarding all limit how freely the hip can move through a stride.
A hip that won’t extend behind you can’t produce a full step on that side, which shortens the step and produces a limp — the same mechanism described in how to improve your step length.
Figuring Out Which One Is Yours
Do these with a counter or doorframe in reach.
If you’re less than three months out, or you haven’t been cleared for independent exercise, check with your surgeon or PT first.
The mirror test. Stand facing a full-length mirror, fingertips on a counter. Lift the non-operated leg so the knee comes up. Hold 30 seconds. Watch your pelvis, not your foot. Does the free-side hip sag? Does your torso tip toward the operated leg? Either one points at abductor weakness. Compare against the other side.
The extension check. Stand in a split stance with the operated leg behind you and gently press your hips forward. Compare how far that hip extends against the other side. A clear difference points at stiffness rather than weakness. If you had an anterior approach, make sure you’re clear from all precautions before trying this one.
The video test. Have someone film you walking 30 feet from behind and from the side. Watch for a pelvic dip, a torso lean, a short step on one side, or a foot that turns out. This is also the single most useful thing you can bring to your next appointment.
The habit check. Try walking deliberately slowly while consciously spending equal time on each leg. If your limp noticeably improves when you concentrate, that’s a strong sign the problem includes a motor habit — because a purely mechanical limp doesn’t respond much to attention.
That last test is the one most people find surprising, and it’s genuinely good news.
That said, I know from experience that breaking a years old habit can be tougher than you think.
What to Do About It
Two parts: most people do the first and skip the second, then wonder why the limp is still there.
Part 1: rebuild the muscle
Start where you can succeed, not where you think you should be.
And again, please clear this with your surgeon or PT first, especially the side-lying work — hip precautions vary by surgical approach and by how long ago you had surgery.
| Exercise | Dose | Notes |
|---|---|---|
| Side-lying leg raise | 3 × 12 each side, daily | Lead with the heel. Confirm this is allowed for your approach |
| Standing hip abduction, hand on counter | 3 × 12 each side | Torso stays upright — no leaning away |
| Wall press | 3 × 20 seconds each side | Stand side-on to a wall, press the inside knee into it. Works the standing leg |
| Supported single-leg stance | 3 × 20–30 seconds each side, daily | Fingertips only, mirror in front of you |
| Sit-to-stand without hands | 3 × 5-10 | General strength, and a good daily marker of progress |
| Step-ups onto a 6-inch step | 3 × 10 each side | Watch that the knee doesn’t cave inward |
Expect 6 to 12 weeks of consistent work before your walking looks different. That’s not slow, that’s normal — and knowing it in advance is what keeps people from quitting in week three.

Part 2: retrain the walking pattern
This is the half that removes the limp, and almost nobody is told to do it.
Mirror walking. Walk toward a full-length mirror with one instruction: keep the hips level. Visual feedback beats verbal cues for this.
Equal-time walking. Walk deliberately slowly, consciously spending the same amount of time on each leg. Slowing down strips out the momentum you’d otherwise use to hurry past the weak side.
Counted steps. Count one-two, one-two out loud as you walk, forcing an even rhythm. An uneven limp shows up as uneven timing, and the count makes it audible.
Long-corridor walking. Find the longest straight, uninterrupted walk you have access to and use the cue heel first, push back.
Do these when you’re fresh. Gait practice at the end of a tiring day rehearses the compensations rather than the correction.
And keep the cane honest
If you’re still using a cane past the point you need it, it could be quietly holding the limp in place — it lets you offload the operated side, which means the abductors never get asked to do their job.
The reverse is also true: dropping the cane too early forces a bigger compensation and can entrench a worse pattern.
This is a judgment call worth getting from a physical therapist who watches you walk, and it’s also worth checking you’re using the device correctly in the meantime.
As a physical therapist myself, I’ve had more patients than I’d like tell me that their health care provider told them to stop using their cane way too early so that their hip would get stronger.
It’s true, removing the cane will ask your hip muscles to work harder – but if they’re not ready to handle the load yet, doing so can increase fall risk or make the limp worse (which can aggravate your knees, back, or other body parts).
If you’re not sure about whether you actually need your cane any longer, it’s worth a physical therapy consult.
When to Call Your Surgeon
Most persistent limps are muscular. Some are not. Contact your surgeon promptly if you have:
- Pain that is getting worse rather than better, particularly in the groin or thigh with weight-bearing
- Fever, chills, redness, warmth, or drainage around the incision, at any point after surgery
- Night pain that wakes you
- A sensation of the hip giving way, clunking, or slipping
- A new limp that appears after a period of walking well
- Numbness, tingling, or weakness in the leg or foot
- A leg that suddenly feels noticeably longer or shorter than before
None of these are things to work through with exercises. Get them looked at.
Final Thoughts
A limp six months after a hip replacement is a frustrating place to be, precisely because everything on paper says you should be finished.
But the operation replaced a joint, not a walking pattern.
The muscles that hold your pelvis steady were weak before surgery and disrupted by it, and the way you learned to walk while your hip hurt is still sitting in your nervous system waiting to be overwritten.
Neither of those resolves on its own with more time – they resolve with loading and with deliberate practice.
Start with the mirror test this week and write down what you see.
If your pelvis dips or your torso leans, you need to strengthen those hip abductors.
And if your limp improves when you concentrate on walking evenly, you’ve found a habit — and that’s the most trainable version of this problem there is.
And if you’re past three months with no clear plan, ask your surgeon for a referral back to physical therapy.
Being discharged from rehab isn’t the same as being finished, and a persistent limp is a legitimate reason to go back.
Frequently Asked Questions
Is it normal to limp six months after a hip replacement? It’s common, but it isn’t something to accept as permanent. A lot of people walk without an obvious limp on level ground by three to six months. Past six months, a limp usually reflects abductor weakness, an unbroken pre-surgical habit, or both — and both respond to targeted work.
Will the limp go away on its own? Usually not, past the early months. Time heals the surgical site; it doesn’t strengthen muscle or rewrite a motor pattern. Those need loading and deliberate practice.
Does a limp mean the surgery failed? Rarely. Persistent limp is far more often about the muscles and habits around the joint than the joint itself. That said, worsening pain, fever, night pain, or a feeling of instability are different — those warrant a call to your surgeon.
Why does my operated leg feel longer? Very common, and often a sensation rather than a measurement. After years with a shortened arthritic hip, a corrected leg frequently feels too long while your body recalibrates. If it persists or causes problems, ask to have it measured properly.
I finished physical therapy and still limp. What now? Ask for a referral back. Discharge from rehab is usually driven by insurance authorization and functional milestones, not by whether your walking pattern is necessarily fully restored. A persistent limp is a reasonable reason to return, and a fresh gait assessment is worth asking for specifically.
Can I do these exercises if I had an anterior approach? Precautions differ by approach and by surgeon, and they change as you get further out. Ask your surgeon or physical therapist about the side-lying and crossing-over movements specifically, rather than assuming the general rules apply to you.
This article is educational and is not a substitute for individual assessment. Do not begin new exercises after joint replacement surgery without clearance from your surgeon or physical therapist. Worsening pain, fever, or a feeling of instability should be reported to your surgeon promptly.
