Enhanced recovery after joint replacement: less opioids, earlier walking, and what GPs can tell patients

Orthopaedic surgeons (names not clearly stated in Otter)

Two hip/knee arthroplasty surgeons practising at Gold Coast Private (and discussing public work at Gold Coast University / Robina). First names heard in the recording as Rick and Price (Otter also heard Bryce / Christ). Closing applause may include surnames, but Otter is unclear — we do not invent surnames. Colleagues named clearly: Nick Wickworth (next speaker that day) and Zeke Tan (upper limb).

Setting

Gold Coast CPD / ortho day, 6 June 2026. Practice relocating (as of the talk) toward an RDX building near Gold Coast Private.

Why this topic now

Surgeons love talking about the operation. This talk is deliberately about what happens afterwards — and the speakers call it one of the most dramatic changes in joint replacement worldwide.

• Theatre skill was already good; ward care historically was not: long GA, morphine, constipation, drowsiness, days in bed, miserable early experience.
• Knee dissatisfaction still matters: historically ~15–20% dissatisfied (roughly 80–85% satisfied; ~10% “don’t like it” despite okay mechanics; ~5–8% frankly bad — stiffness, infection, worse pain). Hips have usually scored better on satisfaction.
• Younger working-age patients now get replacements because implants last longer — they ask “how soon can I get back to life/work?”
• Cost across public and private: joint replacement is a large spend in an ageing population; doing it with similar or better outcomes for less waste frees capacity.

What recovery used to look like

Training-era pathway (as described): almost everyone got a general anaesthetic, long cases with more blood loss, drains, urinary catheters, then two days in bed on as much morphine as needed. Outcomes of the joint could still be good — but that first phase was awful.

Enhanced recovery is an evolution, not overnight magic. The goal is a better perioperative experience for frail elderly and young “go-getters” alike.

What keeps people in hospital

Speakers frame length of stay as the sum of correctable barriers:

Enhanced recovery building blocks

Nausea, steroids, and opioids

• Post-op nausea/vomiting is treated as largely preventable: multimodal antiemetics intra-op; pre-emptive post-op meds in high-risk patients.
• High-dose dexamethasone intra-op (speakers: even in many diabetics) — anti-nausea and anti-inflammatory. Day-1 white cell count around 22 can be expected; speakers say infection-risk fears have been dispelled in this context.
• Short oral steroid course home for ~3–4 days unless type 1 / insulin-dependent diabetes (as described).
• Less opioid → less nausea → more walking. Prefer oral tablets only on the ward — no PCA / IV / subcut opioids in their pathway — so home looks like hospital.

Short-acting spinal, no catheter habit

• Spinals now typically wear off in about 90–120 minutes; many patients move feet before leaving recovery and walk on the ward within ~2 hours.
• Urinary catheters largely dropped because old long spinals needed them.
• Morphine in the spinal largely abandoned (maybe fentanyl or plain local); speakers report far less urinary retention (one said none in ~2 years after stopping spinal morphine).

Local anaesthetic and blocks

Periarticular local anaesthetic / nerve blocks around the knee are described as a game-changer over ~5+ years — little pain for many in the first ~12 hours after the spinal wears off, enabling opioid avoidance.

Early mobilisation and “not a sick person”

• Sit out for meals day of surgery; own pyjamas/clothes; bathroom independence when safe.
• Walk as soon as spinal has worn off and blood pressure is okay — often within 1–2 hours of hitting the ward.
• That early window (blocks still working) builds confidence: “this is not that big a deal.”
• VTE: early walking linked to near-zero clot rates in mobilisers; historical high VTE reflected bed rest. Immobile, nauseated, high-pain patients remain the higher-risk group in their framing.

Global trends and Australia’s lag

Primary goal: easier, faster recovery. Secondary effect: length of stay falls because day-0/day-1 function matches what used to appear at day 4–5.

Drivers overseas: Scandinavian cooperative systems and data; COVID as a game-changer — UK ambulatory (day-case) facilities when wards were full; North American patients refusing COVID-full hospitals and asking for day surgery. Different drivers, same shift from “nice idea” to daily practice.

What they saw in US day centres

Speakers describe touring purpose-built northeast US orthopaedic day centres (~2 years before the talk). Differences were often subtle, not a totally different operation:

• Consistent messaging across the whole journey — hard when neighbours and mixed hospital staff still say “five days then two weeks rehab.”
• Nurse navigator (arthroplasty) — prep, day-of presence, calls day 1 / 3 / 7 — heads off “is my red swollen knee normal?” re-presentations.
• Early sit-out and walk rather than a day in bed.
• Clinical stack: short spinal, antiemetics, blocks/LA, (and locally) pre-op carbohydrate drinks for afternoon lists, tranexamic acid IV ± topical, no catheters, oral-only analgesia.

Implementing at Gold Coast Private

• Brought US lessons into local practice with hospital buy-in in theatre and on the ward.
• Nurses reportedly prefer these patients — less urinary retention, less bed-bound workload.
• Follow-up shifted to two weeks (when patients look more like old six-week reviews): wound check, opioid wean, encouragement to do more.
• Support network still evolving; formal hospital “enhanced recovery programme” discussed as delayed around ownership transition (speakers referred to Mata / Matha takeover timing).
• Health-fund payment quirks: hospitals can be paid less if discharge is “too early” (e.g. day 2 vs day 3) — described as a major Australian barrier vs flat-rate models.

Robotics as one theatre tool

Gold Coast Private described as an early, busy robotic joint centre (robot purchased ~late 2016 / 2017). Speakers: robots don’t operate alone — they help accuracy and soft-tissue sparing (CT-planned Mako emphasised). Cited associations: less soft-tissue damage, lower opioid need in studies, lower inflammatory response, better early scores. Registry/discussion points from the talk:

• Robotic knees rising nationally (speakers expected ~50% of knees in a near-term registry paper; hips ~11% at talk time).
• Cited Simon Young paper: shorter stay, fewer manipulations for stiffness, better mid-term PROMs, similar complications/readmissions vs non-robotic.
• AOANJRR framing: Triathlon with Mako vs other robotic TKAs — lower revision (p~0.002 cited); Triathlon alone already strong at 15 years; robot further improves, largely via less instability from better placement.

Inpatient rehab: evidence vs habit

• Australian rehab stays often ≥5 days (local rehab units may require minimum stay).
• Anecdote: revision patient who “must go to rehab” after prior Sydney messaging — walking independently day 1; rehab declined him as “too good”; mindset took days to shift.
• Claimed evidence direction: no better outcomes from inpatient rehab for many; some data that patients recover faster without it. Selected social/comorbid cases still benefit.
• Physio after discharge: prefer local clinic visits that normalise getting dressed and driving; “rehab at home” insurer products described as variable/poor lately; for well-informed motivated patients, literature cited as no difference at 6 weeks with/without physio.

Safety, readmissions, who benefits

• Every patient benefits from the principles — frail patients may go home day 4 instead of 7–8, not only the “day-case candidates.”
• Cited benefits: less hospital-acquired infection risk with shorter stay, better sleep/food at home, lower DVT risk with movement, patients control oral analgesia → observed lower opioid use than feared.
• One speaker: essentially unchanged readmission rate with shorter stay (one anxious overnight X-ray stay in 12 months recalled).
• Danish day-case vs overnight data: no difference in 30-day known revision / manipulation rates in the slide discussed; national day-case pathway with in-hospital Clexane only then nil on discharge cited with very low VTE (~0.2%) — speakers still anticoagulate in Australian practice (often low-dose aspirin ~1 month for routine patients) for medicolegal/hospital reasons.
• Western Health (Victoria): before/after ERAS — lower readmissions, shorter stay, fewer complications in hips and knees; applied to all joint patients (not only low-risk), average LOS ~5.5 → ~2.9 days.

What GPs can tell patients

• GPs are part of the support network and messaging. Conflicting neighbour/hospital folklore is a major barrier.
• Speakers hope less GP burden: they see patients at two weeks, check wounds, manage pep talks; software allows wound photos messaged to rooms.
• Some patients still need an early opioid top-up script at ~1 week — dose/home pack is gauged from first 24 hours; others take almost none.
• Expectations they push by ~2 weeks: stationary bike, pool, progressing off crutches, earlier driving if insurer/legal OK.
• If worried about any of their joint patients: contact the surgeon — “journey together.”

Q&A highlights

• VTE prophylaxis duration: more about agent than ERAS vs old pathway — routine patients often low-dose aspirin ~1 month rather than injectable DOAC/LMWH for everyone; risk-stratify prior clots / high risk.
• Dexamethasone home dose (as answered): typically 4 mg BD for 4 days.
• Aspirin on discharge: one speaker has used it ~15 years; US ~80% go home on aspirin — framed as international standard of care, not a fad.
• Public sector: hard to fund change when average LOS already meets KPI; Western Health report cited as ~$2.60 saved per $1 spent but still hard to move bureaucracy. Principles still applied at Uni Hospital with a more comorbid cohort.
• Selection bias worry on Western Health: speakers say protocol applied to everybody; point is better peri-op care, not only day surgery.
• US drivers: COVID and patient preference more than insurance copays as the main accelerator.

Take-home messages for clinic

1. Enhanced recovery = fix nausea, pain, long spinals, tubes, and bed rest — length of stay falls because readiness moves earlier.
2. Expect short-acting spinals, blocks/LA, dexamethasone (± short home course), oral-only opioids, early walk, fewer catheters.
3. Align your messaging with the surgeon: home can be the best rehab for many; inpatient rehab is not mandatory for good outcomes.
4. Two-week surgical review + wound-photo pathways should reduce — not increase — GP firefighting; still call early if unsure.
5. Robotics is one tool in a whole pathway; satisfaction and opioid sparing come from the package, not one gadget.
6. Australian system barriers (health-fund pricing, rehab culture, public KPIs) explain why local LOS still lags US/Europe — not because implants differ.
