Robotic Hip Replacement in Honolulu
Serving Honolulu and urban Oahu. Robotic-assisted hip replacement pairs precise 3D planning with the muscle-sparing anterior (bikini) approach — designed for accurate implant positioning and a faster, more confident recovery.

How robotic-assisted hip replacement works
The robot is a tool that helps Dr. Morton plan and execute your procedure precisely. It assists the surgeon — it does not perform surgery on its own.
3D plan from your CT
A pre-operative CT builds a 3D model of your hip, so implant size, leg length, and alignment are planned to your anatomy with the ROSA® or CORI® system.
Surgeon-controlled precision
Dr. Morton uses the system's real-time data to position the socket and stem accurately, helping restore leg length and reduce the risk of dislocation.
Anterior, muscle-sparing
Where appropriate, the anterior (bikini) approach works between muscles rather than cutting through them — designed to support a quicker early recovery. Recovery varies.
Guided recovery
You're up and moving soon after surgery with a plan from our in-house PB&J Physical Therapy team — right here on Oahu.
Where Your Care Happens
Local clinic, expert surgery
Robotic-assisted total hip replacement is performed at Adventist Health Castle with the CORI® system, using the muscle-sparing anterior (bikini) approach.

Is It Right For You?
Who is a candidate for hip replacement
Hip replacement is usually considered for advanced arthritis when non-surgical care — activity changes, therapy, medication, and injections — no longer gives lasting relief. The American Academy of Orthopaedic Surgeons notes that the decision is based on your pain and loss of function, not your age.
Because we offer both surgical and non-surgical care, Dr. Morton will review every option honestly and recommend surgery only when it is the right fit. Not everyone is a candidate.
You may be a candidate if
- Hip or groin pain limits walking, stairs, or sleep
- Stiffness makes putting on shoes or socks hard
- Non-surgical care no longer gives lasting relief
- X-rays show arthritis or joint damage
What To Expect
From evaluation to recovery
Timelines are general and vary by patient.
Before surgery
An evaluation and X-rays confirm the diagnosis. If you proceed, a pre-operative CT builds your 3D plan, and we coordinate medical clearance and prehab exercises to prepare.
Day of surgery
Your procedure takes place at Adventist Health Castle or The Queen's Medical Center, with the full resources of a hospital on hand.
Recovery
You begin moving soon after surgery with guidance from our in-house PB&J Physical Therapy team, coordinating your rehab right here on Oahu.

2-Minute Check
Am I a candidate for robotic hip replacement?
Answer a few quick questions. This is educational and is not a diagnosis — only an evaluation can tell for sure.
Do you have hip or knee pain that limits walking, stairs, or sleep?
Have non-surgical treatments (therapy, injections, medication) stopped giving lasting relief?
Have X-rays shown arthritis or joint damage, or has a provider mentioned it?
You may be a strong candidate.
Your answers suggest robotic hip replacement could be a good fit. The next step is a simple evaluation, where we'll confirm with an exam and imaging and review every option with you — surgical and non-surgical.
This tool is educational and not a diagnosis. Not everyone is a candidate; only a clinical evaluation can determine what's right for you.
You might be a candidate — let's talk.
Some of your answers point toward robotic hip replacement, but the right path depends on the details. A short evaluation will give you a clear, honest answer and a plan.

Let's take a closer look.
Your answers don't point clearly to robotic hip replacement yet — but that doesn't mean we can't help. We'll evaluate what's going on and point you to the care that fits, often starting with non-surgical options.

Evidence & Research
What the evidence says about robotic-assisted hip replacement
Robotic assistance and the muscle-sparing anterior approach are tools that help the surgeon plan and position your implant. Here is a plain-language summary of what peer-reviewed research and the American Academy of Orthopaedic Surgeons report — with the honest limits.
Total hip replacement is one of the most successful operations in modern medicine — it reliably relieves arthritis pain and restores mobility for the great majority of patients.1
It is also durable. The American Academy of Orthopaedic Surgeons reports that the majority of hip replacements continue to function well many years after surgery, and that serious complications are uncommon.2
Robotic assistance is designed to improve accuracy. In a systematic review and meta-analysis, robotic-arm–assisted hip replacement was associated with more accurate placement of the socket within the target ("safe") zone than manual technique.3
The muscle-sparing anterior approach may support faster recovery in the first few weeks, though differences between approaches tend to even out within a few months. Recovery varies for every patient.4
Robotic technology assists the surgeon; it does not perform surgery on its own. Comparisons are to conventional (non-robotic) technique only. Not everyone is a candidate, and individual results and recovery vary. This page is educational and is not a substitute for medical advice.

Patient Reviews
What patients say
“Dr. Morton has an excellent bedside manner. He really took the time to talk with me about all of my options for my hip replacement. He did my re-do hip replacement 3 months ago and I haven't felt this good for years! Thank you Dr. Morton for helping me walk again.”
— Verified patient· Healthgrades review
“I had left hip surgery on Tuesday and went to physical therapy at his office the next day. I am doing awesome — I have minimal pain! Dr. Morton and the office staff, Bryson and Chelsea the PTs, Carol the scheduler... this is where you want to have surgery!”
