So, you’re in Honolulu, your knee is screaming after a weekend at Sandy’s, and you keep hearing one name: Jay Marumoto MD Honolulu. People talk about him like he’s the guy who fixes the "unfixable" joints. But here’s the thing. Most people think an orthopedic surgeon is just someone who hacks into bone. That’s a huge misconception. Dr. Jay Marumoto is basically a craftsman of the microscopic. He’s the guy who spends his days doing "intra-articular suturing"—which is basically high-stakes sewing and knot-tying inside the tiny, cramped space of a human joint.
It’s pretty wild when you think about it.
Honestly, finding a doctor in Hawaii who has the technical chops of a Swiss-trained specialist but also understands the local culture isn't as easy as you'd think. Dr. Marumoto is a local boy, born and raised. His roots go deep. His grandfather was a Supreme Court Justice and his mother was a State Representative. That legacy matters because it means he’s not just passing through; he’s part of the community fabric.
Why the Advanced Arthroscopy Training Actually Matters
Let’s get technical for a second. Most surgeons can do basic arthroscopy. But Marumoto went to the Southern California Orthopedic Institute (SCOI). That place is widely considered the mecca for "advanced" techniques. Instead of opening you up like a holiday turkey, he uses incisions that are barely a quarter-inch wide.
Through those tiny holes, he’s repairing cartilage and tendons with fiber-optic cameras.

He also spent time in Davos, Switzerland, at the AO Institute. If you know anything about hardware, you know the Swiss don't mess around with precision. He brought that reconstructive-fracture expertise back to the islands. This is why he ended up as the Chief of Orthopedic Surgery at Queen’s Medical Center. He wasn't just doing the work; he was leading the department.
The Sideline Years: More Than Just a Title
You’ve probably seen him on the sidelines if you follow University of Hawaii athletics. He wasn't just a "consultant." From 2001 to 2007, he was the guy June Jones relied on for the UH Football team. He was there for the legendary 2007 Sugar Bowl run. He’s also been courtside for UH Men’s Basketball.
When a 250-pound linebacker goes down, the pressure is on. You have to make a call that affects a kid's entire career. That kind of high-pressure environment is where Marumoto honed his ability to diagnose sports injuries fast and accurately. He’s not just looking at an MRI; he’s looking at the mechanics of how the injury happened in real-time.
What He Actually Treats (It’s Not Just ACLs)
While he’s famous for knee reconstructions, his scope is actually way broader. A lot of patients come to him for Shoulder Impingement Syndrome—that annoying, pinching pain that makes it impossible to reach for the top shelf.

Here is a quick look at what his practice at Orthopedic Associates of Hawaii actually handles:
- Complex Knee Work: We're talking ACL, MCL, and meniscus transplants. He’s one of the few doing the BEAR implant for ACLs, which helps the ligament actually heal itself.
- Shoulder Mastery: Rotator cuff repairs and labral work for people who’ve "thrown out" their shoulder.
- Joint Replacement: When the cartilage is just gone, he does total and partial knee replacements using computer-assisted technology.
- Ankle and Elbow: From Achilles tendon ruptures to tennis elbow that won't quit.
The Patient Experience: The "Good and the Bad"
No doctor is perfect, and if you’re looking for a surgeon who is going to spend three hours holding your hand, you might be looking in the wrong place. Surgeons are busy. Jay Marumoto MD Honolulu is no exception. He’s a high-volume specialist.
But if you look at the data—over 150 reviews with a 4.7-star rating—the consensus is clear. Patients say he "explains conditions well" and is "trustworthy." The staff at his Hale Pawa’a office on Beretania Street are known for being efficient, but the office is busy. You're going there because you want the best hands in the state, not necessarily because you want to hang out in the waiting room.
He’s an Assistant Clinical Professor at the University of Hawaii, too. That means he’s literally teaching the next generation of surgeons how to do this. If the guy teaching the class is the one doing your surgery, you’re usually in a good spot.

Real Talk on Recovery
Surgery is only 50% of the battle. Marumoto is a big advocate for aggressive, smart rehabilitation. He’s even published research on things like "Accelerated Recovery Performance" (ARP) trainers, which use high-pulse electrical stimulation to stop muscles from wasting away after an ACL reconstruction.
He knows that for a surfer or a hiker in Hawaii, "getting better" isn't enough. You want to get back to the water.
Actionable Next Steps for You
If you’re considering seeing Dr. Marumoto, don't just walk in blind. Here is how to actually navigate the process:
- Check Your Insurance Early: He takes almost everything—HMSA, UHA, Medicare, Aetna, Cigna—but always call the Hale Pawa’a office (808-536-2261) to confirm.
- Bring Your Imaging: If you already have an MRI or X-ray on a disc, bring the physical disc. Don't rely on the "portal" to work perfectly when you're sitting in the exam room.
- Ask About Minimally Invasive Options: Specifically ask if you are a candidate for arthroscopic repair versus an "open" procedure. The recovery time difference is night and day.
- Prepare for Waipahu or Honolulu: He has offices in both locations. If the Honolulu schedule is backed up, ask if he has a sooner opening at the Ka Uka Blvd location in Waipahu.
Don't wait until you can't walk to get a consult. Orthopedic issues like rotator cuff tears or meniscus frays tend to get worse, not better, with "rest" if the mechanical tear is significant enough. Getting an expert opinion from someone like Marumoto isn't just about surgery; it's about getting a roadmap for your mobility.
