Get Back To Life Pain-Free with Dr. Morton

Latest Technology, Personalized Care

Hip and Knee pain is very common and can interfere with your everyday life and stop you from doing the things you want to do. The hip and knees are joints that are the largest joints in the body and very easy to incur. An injury to your hips or knees can prevent you from running, walking, sitting and many other day to day activities that we take for granted! Common causes of pain include arthritis, avascular necrosis, meniscus tears, fractures and ligament sprains (ACL).

Some orthopedic doctors only want to talk with you about surgery. There are many treatment options that might help you recover. Dr. Morton will talk with you about both surgical and nonsurgical options to recover quickly and get you pain-free faster.

Are you tired of suffering from Hip or Knee pain? You don’t have to suffer! Talk with Dr. Morton today about different treatment strategies.

Hi, I’m Dr. Paul Norio Morton.

I was raised in Kea’au on the Big Island. While attending college in Ohio, I was also a volunteer firefighter. The feeling I got when helping in rescue operations convinced me that I wanted to become a doctor. My love of sports, helping people, and technology have come together in my Orthopedic Practice at the Queen’s Medical Center.

I specialize in hips and knees and am the first Orthopedic Surgeon in Hawai’i who is Fellowship-trained in Robotic joint Replacement. Some of my patients have even nicknamed me “The Robot Doc.” I believe robotic surgery is more precise, less invasive has fewer complications, and will get you back out there feeling pain-free faster.

And although I use the latest technology, I still believe in good, old-fashioned, friendly, and personalized care.

If you’re having issues with your hips or knees, please give me a call today. Let’s find the best solution for you and get you back to being active, again!

Mahalo for entrusting me with your care,

Paul Norio Morton, M.D.

Smart Implants (Persona IQ®)

Smart implants are devices that are designed to monitor a patient’s condition and provide feedback to the surgeon on how the implant is performing. This information can be used to make sure that the implant is functioning properly and adjust the treatment accordingly if necessary. Dr. Morton offers the only smart implant for total knee replacements with Persona IQ®

Robotic-Assisted Hip and Knee Replacement Surgery

Robotic-assisted joint replacement surgery is a minimally invasive approach to hip and knee replacement surgery that is made possible by advances in surgical robotics technology. In traditional joint replacement surgery, large incisions are made in order to access the joint. However, with robotic-assisted surgery, smaller incisions are used and the surgeon is able to control a robotic arm to perform the surgery with greater precision. This approach results in less tissue damage, less pain, and a quicker recovery for patients.

Minimally Invasive Hip and Knee Replacement – Smaller Incisions, Faster Recovery

Minimally invasive surgery performed by Dr. Morton typically involves smaller incisions compared to traditional knee replacements. Below is a picture of a patient who recently underwent a right minimally invasive robotic total knee replacement 5 months after surgery compared to a scar from surgery performed several years ago by a different provider in Hawaii. Over time, the surgery scars gradually fade in color. The surgical incision is roughly half the length compared to the competitor’s incision. Dr. Morton’s philosophy is that with smaller incisions, there is less pain and a faster recovery.

Similarly, Dr. Morton performs minimally invasive robotic-assisted anterior hip replacements via the Bikini approach. The bikini incision is a variation of the anterior approach where the incision is parallel to the skin folds. By making the incision parallel to the skin folds, it follows Langer’s lines. Following the langer’s lines allows the incision to follow the natural orientation of the collagen fibers in the dermis, allowing for improved healing. Patients with elevated BMI, often have increased difficulty with healing due to the folds of the skin. This approach changes the location of the incision, decreasing the change of wound complications and infection. The term “bikini” is used because the incision is small and well hidden beneath clothing. These incisions are typically 2 – 4 inches long compared to the traditional 5 – 10 inch long incisions.

ACL Repair with BEAR®

The ACL (anterior cruciate ligament) is one of the major stabilizing ligaments in the knee joint. Tears of the ACL are common injuries that can cause knee instability. BEAR® (Bridge-Enhanced ACL Repair) is a new surgical technique that uses a biological bridge to repair tears of the ACL while minimizing damage to surrounding tissue. This allows for the restoration of the anatomy of the ACL.
