Why opioid-sparing matters — especially here
Opioids control pain at a price: nausea, constipation, fog, falls, and for a meaningful minority, dependence that outlives the surgery. Hawai‘i's families know these stories. The modern answer isn't asking patients to tough it out — it's engineering the operation and anesthesia so severe pain never gets established. Studies associate fellowship-trained joint surgeons with lower patient opioid use; protocol design is a large part of why.
Layer one: create less pain in the first place
Pain control starts with the scalpel, not the pharmacy:
- Subvastus knee approach — the quad is never cut, so it doesn't scream during rehab
- Anterior hip approach — between muscles rather than through them
- Tourniquet-free technique — eliminates the deep thigh ache patients historically blamed on 'the knee'
- Robotic precision — less soft-tissue disruption per millimeter of correction
Layer two: multimodal anesthesia
During and after surgery, several small hammers replace one sledgehammer: regional anesthesia for the operation itself, targeted nerve blocks, long-acting local anesthetic infiltrated around the joint, and scheduled non-opioid medication — acetaminophen and anti-inflammatories on the clock, not as afterthoughts — plus cryotherapy, elevation, and compression at home (the full home plan lives at medication after surgery). A small opioid supply exists as rescue, not backbone; many patients barely open it.
Layer three: iovera° — freezing pain before surgery
For knee replacement, Dr. Morton offers a step most practices don't: iovera° cryoneurolysis before surgery. A handheld device precisely freezes the sensory nerves around the knee — no drugs, no permanent damage — dialing down pain signaling for roughly up to six months while nerves regenerate. Patients arrive at surgery with the pain pathway already quieted, needing less of everything afterward. It's also used standalone for arthritis pain in patients not ready for surgery.
