About Paul N. Morton, MD

Fellowship-Trained Hip & Knee Replacement Surgeon in Hawai‘i · FAAOS · FAAHKS

A local boy from Kea‘au who trained at the University of Chicago and Charité Berlin, came home, founded Pacific Bone & Joint — and quietly made Hawai‘i one of the most advanced places in the Pacific to get a new hip or knee.

From fire trucks to operating rooms

Dr. Morton was born and raised in Kea‘au, just outside Hilo on Hawai‘i Island, and graduated from Kea‘au High School. College took him 4,000 miles away to Antioch College in Yellow Springs, Ohio, where he double-majored in chemistry and biomedical science — and trained as a firefighter on the side.

It was the fire service that revealed the career. As a firefighter and EMT with Miami Township Fire-Rescue, he pulled patients from wrecked cars, worked search-and-rescue calls, and answered medical emergencies at all hours. The adrenaline was part of it; the durable part was the satisfaction of taking care of people on the worst day of their lives. He went looking for a way to do that for a living — and found medicine.

He came home to earn his MD at the University of Hawai‘i’s John A. Burns School of Medicine, spending half of his third-year clinical rotations back on Hawai‘i Island. Even then his training looked outward across the Pacific, with rotations in medicine and surgery at the University of Santo Tomas in Manila and in orthopedics at the Hamamatsu School of Medicine in Japan.

Residency in orthopedic surgery took him to St. Luke’s University Health Network in Bethlehem, Pennsylvania — including pediatric orthopedic training at Children’s Hospital of Philadelphia — and in his final year he served as chief orthopedic resident. Then came fellowship training: an ACGME-accredited fellowship in adult hip & knee reconstruction at the University of Chicago, where his mentors taught him robotic joint replacement and how to rescue joint-replacement disasters, and an AO Trauma fellowship at Charité Universitätsmedizin in Berlin, one of the largest university hospitals in Europe.

Coming home — and building something new

He could have practiced anywhere. He chose home — because his dream was always to bring that training back to the islands, and because patients in Hawai‘i and the Pacific shouldn’t have to fly 2,500 miles for mainland-quality joint care.

To deliver it, he founded Pacific Bone & Joint and PB&J Physical Therapy — bringing surgical care, physical therapy, and imaging under one roof, with clinics in Honolulu (Ala Moana), Kunia (West O‘ahu), Hilo, and Kailua-Kona. From a sports injury to a failed hip or knee replacement no one else will touch, his practice is built to carry patients from first visit to full recovery without leaving the islands. In clinic, patients are cared for by Dr. Morton alongside physician assistant Justin Kapono Grandalen, PA-C, and the PB&J Physical Therapy team — meet your team.

Firsts

Milestones he brought to Hawai‘i

  1. 2022

    Hawai‘i's first robotic-assisted total hip replacement

    Performed in 2022 on the ROSA platform.

  2. 2022

    First robotic joint replacement on Hawai‘i Island

    Performed March 3, 2022 at Kona Community Hospital.

  3. 2022

    Hawai‘i's first Persona IQ® smart knee replacement

    Implanted October 4, 2022 with robotic assistance — the first smart knee implant authorized by the FDA (De Novo, 2021).

  4. 2025

    Hawai‘i's first arthroscopic MACI cartilage implantation

    In 2025 he became the first surgeon in Hawai‘i to perform arthroscopic MACI — restoring knee cartilage with the patient’s own cultured cells through a minimally invasive approach. An early adopter of robotic knee replacement, he has helped bring each new generation of the technology to the islands.

An early adopter of robotic knee replacement in Hawai‘i, Dr. Morton pioneered the technique at The Queen’s Medical Center and brought the first robotic joint replacement to Hawai‘i Island. He is certified on all four robotic joint replacement platforms — ROSA®, MAKO, CORI, and VELYS — and was the first surgeon in Hawai‘i fellowship-trained in robotic joint replacement. Patients gave him a nickname for it. The story behind “The Robot Doc” →

What he does

The latest advancements in hip & knee surgery

Hips, knees, and the SI joint — nothing else. That focus is what lets one surgeon take a patient from joint preservation through robotic replacement to the complex revisions other practices refer out.

How Dr. Morton practices

Dr. Morton’s practice centers on the hip and knee — and on helping each patient choose the right operation, or none at all. His focus:

Dr. Morton leads surgical decision-making and performs the joint replacement operation, while other parts of the care pathway may involve physician assistants, nurses, physical therapists, anesthesia providers, and other members of the orthopedic team —meet your team. His practice is Hawai‘i-based, with clinics in Honolulu, West O‘ahu, Hilo and Kona; patients come fromevery part of the islands. Read how he approaches each decision in Not every hip or knee replacement is the same.

Care philosophy: your goals set the plan

Dr. Morton believes everyone deserves a patient-centered, individualized approach — a holistic one that folds your desires and expectations into the treatment of your hip, knee, or SI joint problem.

Not every patient with the same X-ray wants — or needs — the same treatment.

That’s why every consultation covers both non-operative and surgical options, and why the first questions are about you: what hurts, what you’ve tried, and what getting your life back actually looks like — the water, the trail, the golf course, the grandkids. He partners with each patient to understand the problem and the desired outcome, then builds an evidence-based plan around it.

When surgery is the right answer, patients get modern orthopedics —chosen joint by joint, not one-size-fits-all: robotic joint replacement, rapid-recovery protocols, advanced analgesia, opioid-sparing pain control, and cosmetic wound closure. And because he participates in research and regularly visits national and international experts to study emerging techniques, his patients receive the next generation of musculoskeletal care — honestly presented, without a hard sell.

In his own words

Meet Dr. Morton

Two minutes with the surgeon before you ever book a visit — how he thinks about joint pain, surgery, and getting people back to the water, the trail, and the course.

Beyond the operating room

Still a local boy

Out of scrubs, Dr. Morton trains Brazilian Jiu-Jitsu and can be found ringside covering local mixed martial arts events. The rest of his off-hours look like Hawai‘i: biking, swimming, water sports, hiking, and traveling — often to visit the surgeons and engineers building the next generation of joint replacement.

Giving back to the community that raised him is part of the practice, too — from holiday toy drives and support for island keiki programs like the Keiki O Ka ‘Āina family learning centers to educating the public on joint health through local TV, print, and his YouTube channel.

Where he operates

Dr. Morton performs most robotic hip and knee replacements as same-day surgery. Hospital-based surgery, overnight stays when your health calls for them, and hip & knee trauma coverage are on O‘ahu; Hilo Community Surgery Center on Hawai‘i Island is same-day surgery only:

  • The Queen's Medical Center — Honolulu
  • Adventist Health Castle
  • Hilo Community Surgery Center

Clinic visits are available in Honolulu (Ala Moana), Kunia (West O‘ahu), Hilo, and Kailua-Kona — see all locations or call (808) 439-6201.

What are Dr. Morton’s credentials?

Dr. Paul Norio Morton, MD, FAAOS, FAAHKS is certified by the American Board of Orthopaedic Surgery and fellowship-trained in adult hip & knee reconstruction at the University of Chicago and in orthopedic trauma at Charité Universitätsmedizin in Berlin. He is an AO Trauma Fellow, a Fellow of the American Academy of Orthopaedic Surgeons, a Fellow of the American Association of Hip and Knee Surgeons, and the founder of Pacific Bone & Joint.

Why do they call him “The Robot Doc”?

The nickname came from his patients. After Dr. Morton performed Hawai‘i’s first robotic-assisted total hip replacement and first Persona IQ smart knee replacement in 2022, patients started calling him “The Robot Doc” — and the name stuck. He is certified on all four robotic platforms used in joint replacement: ROSA, MAKO, CORI, and VELYS.

What does Dr. Morton treat?

His practice focuses exclusively on hips, knees, and the sacroiliac (SI) joint — from joint preservation, injections, cartilage restoration (in 2025 he became the first surgeon in Hawai‘i to perform arthroscopic MACI), and hip & knee sports injuries to robotic joint replacement, same-day surgery, and complex revision of failed or painful implants.

Where does Dr. Morton see patients?

Clinics in Honolulu (Ala Moana), West Oahu (Kunia), Hilo, and Kailua-Kona — plus telehealth for neighbor island patients and pre-travel video calls for Pacific and international patients. Call (808) 439-6201.

Will Dr. Morton perform my surgery himself?

Yes. Dr. Morton leads surgical decision-making and performs the joint replacement operation himself — no resident or fellow does your case. Other parts of the care pathway may involve physician assistants, nurses, physical therapists, anesthesia providers, and other members of the orthopedic team. In clinic you may see physician assistant Justin Grandalen, PA-C, for some visits and questions, and you can always ask to see Dr. Morton.

Is Dr. Morton from Hawai‘i?

Yes — he was born and raised in Kea‘au, near Hilo on Hawai‘i Island, and returned home to practice after his mainland and international training. He describes himself as a local hapa boy who came home to take care of his own community.
