PAO recovery timeline, week by week.

Clinical procedure: Periacetabular osteotomy (PAO).

Typical, evidence-anchored estimate only. It is not medical advice, not a prediction for your body, and not a substitute for your surgeon or clinician.

Periacetabular osteotomy is a different animal from the keyhole hip surgeries. The pelvis is cut in several places and repositioned, which means the early recovery is governed by bone healing, not soft-tissue irritation — crutches are measured in months, not weeks, and the people going through it are overwhelmingly young women in their twenties and thirties juggling work, study, and sometimes a second hip waiting its turn.

The encouraging part is that the outcome data is genuinely good. In the ANCHOR multicenter cohort — 391 hips followed prospectively — hip pain scores improved from 56 to 84 out of 100 and 93% of patients said they were satisfied at an average of 2.6 years. The early-week pain data is thinner: one diary study tracked people daily through the first six weeks, and between week six and month six the published literature simply goes quiet. This page is explicit about which numbers are measured and which are bridged.

what shapes recovery here

The single biggest variable is your surgeon's weight-bearing protocol. Across 63 published studies, protected weight-bearing — usually about 20-25% of body weight, foot flat, on two crutches — lasts six weeks in some protocols and eight in others, with outliers from four to sixteen. Nothing you do in rehab moves that date much, because it is waiting on the osteotomy cuts to consolidate on x-ray, not on your strength.

Beyond the protocol: whether anything was done alongside the PAO (a hip scope for the labrum adds its own restrictions), whether this is your first side or the second of a staged pair, and what your job asks of your body. Desk work commonly restarts around twelve weeks; heavy physical work closer to six months. One honest caveat for this page: the week-7-to-25 pain numbers are interpolated, because no study has published pain scores in that window.

weeks 02

Weeks 0-2 · the hospital fortnight

The first days are the hardest of the whole arc. A daily diary study that followed PAO patients by automated text message put average pain at 5.9/10 on the first day, 4.7/10 at one week, and 4.1/10 at two weeks — with wide spreads in both directions. Anesthesia teams increasingly use regional blocks (a TAP-block trial cut 48-hour opioid use roughly in half), so your day-one experience depends partly on what was infused before you woke up.

Mobilization starts surprisingly early: most protocols have you up on crutches with foot-flat, roughly 20-25%-of-body-weight contact by day one or two. That isn't walking in any meaningful sense — it's teaching the leg the pattern while the pelvis is protected. Opioid use in the diary cohort peaked around day eight and was essentially zero by week six.

If your pain is rising rather than falling after the first week, or the leg stops tolerating the protected touch-down it previously tolerated, call your surgical team. The modal trajectory is steady decline from day one.

weeks 28

Weeks 2-8 · the long protected stretch

This is the part nobody warns you about emotionally: pain drops to a 2-3/10 plateau by week three and mostly stays there, but you are still on two crutches at a quarter of your body weight, because the bone simply isn't ready. The diary cohort's averages fluctuated between 2.0 and 3.0 from day 20 through day 42 — recovery here is measured on the x-ray, not on the pain scale.

The Delphi consensus that North American hip-preservation physios published in 2022 keeps this phase deliberately boring: hip flexion limited to about 90 degrees and external rotation to about 20 for the first four to six weeks, a stationary bike from week six-ish, and no decisions about weight-bearing made by feel. The protected period ends when your surgeon sees consolidation — six weeks in about a fifth of published protocols, eight in another fifth.

Use the time for the things rehab can legitimately progress: upper body, the non-operative leg, core work within the motion limits, and sleep logistics. People who treat this stretch as a project tend to come out of it less deconditioned than people who treat it as a sentence.

Around week 5, the typical band sits at 2.6/10 (range 0-5.9). Interpolated between adjacent measured points.

weeks 816

Weeks 8-16 · weight comes back

Somewhere in the 8-12 week window — x-ray permitting — you transition to weight-bearing as tolerated, then wean from two crutches to one to none. The physio consensus deliberately refuses to give a calendar date for the last crutch: the criterion is a symmetric gait without a Trendelenburg lean, whenever that arrives. For most people that's somewhere between weeks 8 and 16.

Two practical milestones cluster here. Driving: the only brake-reaction-time study in PAO patients (small, n=26) found most people were not safe at six weeks but had normalized by twelve. And work: in a 242-patient cohort the median return was sixteen weeks, with a quarter back by twelve — desk jobs at the early end, anything physical much later.

Pain in this window is the least-documented of the whole recovery: no study publishes three-month pain scores, so the 2-3/10 you'd expect here is interpolated between the week-six diary data and the six-month cohorts. If your reality is meaningfully above that band — especially groin pain that spikes with each step — flag it rather than assuming it's normal.

Around week 12, the typical band sits at 2.5/10 (range 1.5-5). Interpolated between adjacent measured points.

weeks 1626

Weeks 16-26 · impact, carefully

Running is the gate everyone asks about, and the consensus answer is weeks 20-26, gated on hip-abductor strength reaching roughly 80% of the other side plus your surgeon's sign-off — criteria, not a date. Institutional protocols put elliptical and pool running earlier, around weeks 10-16, which is where most people scratch the cardio itch first.

By six months the Aarhus prospective cohort gives us the first hard pain numbers since week six: rest pain averaging 1.4/10 and activity pain 4.1/10. That gap — quiet at rest, loud under load — is the defining texture of the second half of PAO recovery, and it narrows slowly rather than suddenly.

Heavy or physical work typically restarts in this window or just after it; in the return-to-work cohort, 86% were back by twenty-four weeks across all job types.

weeks 26104

Months 6-24 · sport, bone, and the long tail

Return to sport averages just under nine months across the published series, with return rates between 63% and 91% depending on the sport and the series. The honest footnote: studies measure a real shift from high-impact toward lower-impact sport after PAO — most people get back to being athletes, not always to the exact same athletics.

Bone keeps healing long after function returns. The superior pubic ramus — the slowest of the cuts — shows non-union in roughly half of patients at six months, falling to under 10% by a year, and almost all of those are painless and need nothing. Separately, about one in five patients eventually has the fixation screws removed for irritation, typically a year or more out; it's a small, planned procedure and 75% feel better afterward, so treat it as a common epilogue rather than a complication.

By two years, the Aarhus data shows rest pain at 1.4/10 and the ANCHOR cohort's pain scores at 84/100 — most people are simply living their lives. The fair summary of the literature: expect nine to twelve months before you stop thinking about the hip daily, and up to two years for the last few percent.

questions

Common questions about periacetabular osteotomy (pao) recovery

How long will I be on crutches after PAO?

Plan for two to three months in total. Protected weight-bearing (about 20-25% of body weight, two crutches) runs six to eight weeks in most published protocols, then you progress to full weight and wean off crutches as your gait normalizes — commonly somewhere between weeks 8 and 16. The final crutch is dropped on gait quality, not on a calendar date.

When can I drive after a PAO?

The only published brake-reaction-time study in PAO patients found most were not yet safe at six weeks but had returned to baseline by twelve. Twelve weeks is the defensible planning number for a right-side PAO with a manual transmission; left-side and automatic drivers are sometimes cleared earlier, but that's surgeon discretion, not published data.

When do people go back to work?

Median sixteen weeks in the largest cohort (242 patients), with a wide spread: about a quarter back by twelve weeks, 86% by twenty-four. Desk work sits at the early end — some people manage partial remote work within a few weeks — while heavy physical jobs realistically take five to six months.

Will I get back to sport?

Most likely yes, but on a long clock: the published average is just under nine months, with return rates of 63-91% across series. Studies also document a real shift toward lower-impact sport afterward, so the honest framing is a return to athletic life, not a guaranteed return to your exact pre-dysplasia sport at the same level.

Is it normal to still have pain months after PAO?

Some, yes — especially with activity. At six months the best prospective data shows rest pain near 1.4/10 but activity pain near 4.1/10, and that gap closes slowly through the second year. Pain that is rising rather than flat-or-falling, or rest pain that stays high, is the pattern worth raising with your surgeon.

Do the screws come out?

Only if they bother you. Across published series, roughly 13-24% of patients have symptomatic hardware removed, typically a year or more after surgery, and about three-quarters of them feel better for it. It is a small planned procedure, not a sign the PAO failed.
