Jaime D. Hernandez, MD, is a board-certified orthopedic surgeon who specializes in hip and knee replacement. Each year, he performs over 400 joint replacements. He was specialty-trained in joint replacement surgery at Harvard Medical School's Brigham and Women's Hospital. While in Boston, Dr. Hernandez gained tremendous experience performing complex joint replacements and revising failed joint replacements. He was further trained in techniques of partial knee replacement, anterior hip replacement, and hip resurfacing.

While at Harvard, Dr. Hernandez was a member of the trauma team, treating upper and lower extremity injuries at the region's level 1 trauma center. Caring for patients with these devastating injuries and helping restore their level of function is particularly rewarding to Dr. Hernandez.

He has given several national and international presentations, including one on his technique of computer-navigated knee replacement, which was presented at the International Computer-Assisted Orthopedic Surgery meeting in Paris, France.

Dr. Hernandez was born and raised in the Lehigh Valley of Pennsylvania and attended Easton Area High School. For college, he traveled to upstate New York to attend Cornell University and majored in biology. During his undergraduate years, he took part in basic science and clinical research programs at some of the nation's top research centers, including The Harvard School of Public Health, UCSF's Cardiovascular Research Institute, and UCLA's School of Medicine. Dr. Hernandez graduated from Cornell with honors.

He then attended Northwestern University's Feinberg School of Medicine in Chicago and developed an early interest in orthopedics, specifically in joint replacement. He worked with surgeons in the orthopedic department, researching the use of computers in joint replacement. This work, which was published in the Journal of Arthroplasty, showed that surgeons who use computer navigation in knee replacement achieve better alignment than surgeons who do not.

After graduating from medical school, Dr. Hernandez spent time volunteering in rural hospitals in Colombia, South America, and treated patients with a variety of illnesses.

Returning to New York for his orthopedic surgery residency, Dr. Hernandez chose to attend the State University of New York at Buffalo, as it is the nation's premier center for CAOS (computer-assisted orthopedic surgery) and the site where the first computer-navigated knee replacement in the United States was performed. During residency, Dr. Hernandez's research efforts focused on hip arthroscopy, a minimally invasive technique used to treat sports injuries and some degenerative conditions. His work, which explained how to safely repair the hip labrum, was published in Arthroscopy. Dr. Hernandez excelled during his surgical training, and upon graduation, was honored as the recipient of The Chairman's Award.

In his free time, Dr. Hernandez enjoys traveling, hiking, golf, and reading.

Eric Montoya, PA-C, is the physician assistant to Dr. Hernandez. They are available to see patients at the Van Nuys office.

"I am a 44-year-old with bad hips. I used to jog several miles a week for exercise and to clear my mind. A few years ago, I started experiencing pain in my hips. I thought maybe I was overdoing my running. But I continued to run, just not as far. Last year is when I realized I had enough of the pain. I saw 4 different doctors. I was given shots and had taken medication but was still in pain. I was told I was too young for hip replacements. Finally, I went to SCOI. I saw Dr. Gazmarian first then he sent me to Dr. Hernandez. SCOI staff are on top of everything! I had my surgery set up in 2 weeks. It went very well. Dr. Hernandez checks in with me to make sure I'm doing ok. The care and professionalism is top notch. I am so glad I have been in Dr. Hernandez and his staff's care. Dr. Hernandez is amazing! Thank you so much for giving me my life back!" – L. K. 

"My surgery experience and recovery process for my TKR were better than I expected. I had great results and I will refer Dr. Hernandez to others as well as come to him when it's time for my other knee." – Laura N.   

"Extremely pleased with Dr Hernandez in all phases of care. Provided detailed information and answered all questions prior to surgery. Surgery went as planned and as I was prepared for. Post op has been exactly as I was told it would be and I am very happy with the outcome." – Rich M. 

"After researching SCOI, I found them to be on the cutting edge for this type of surgery. I also chose Jaime Hernandez, M.D. for the method he uses to line up the knee replacement with his computerized system to get the replacement in the perfect spot. I have had my other knee replaced 14 years ago & had it done by Dr. Khrazzi at Kerlon Jobe & the knee has been great, but this doctor no longer does knee replacements. I was also referred to SCOI by my nurse practioner, Stephanie Wade. I know the importance of getting the knee replacement done correctly or you can have no success. I have seen so many people with botched knee replacements. I was amazed at 71 years old how fast I progressed with my recovery. My P.T. therapy instructor said I should be the poster child for SCOI & Dr. Hernandez, as he had never seen anyone recover so fast with such success. Dr. Hernandez even told me his other patients that were in same time frame as me were all complaining of not being able to sleep, in pain etc. I went off pain meds after the 2nd week of surgery. I attribute my success to Dr. Hernandez' technique with the computerized system in lining up the knee to my success. I am very grateful I found SCOI." - Shirley D.

"I broke the neck of my femur. Dr. Hernandez saw me right before the operation and was very calming and encouraging. He explained exactly what he was going to do and what I could expect. He told me I had the best break possible and could expect a rapid recovery. I felt reassured and positive. I have a small scar and my recovery has gone very well. Dr. Hernandez is a great surgeon!" - Barbara B.

"It is hard to believe, but I have never had a better experience before and after surgery. My doctor was right on time. Him and his staff made me feel I was in good hands." - Michael M.

I walked around for nine months, being misdiagnosed, from one Doctor to another, until I went to Dr. Hernandez. He showed me my X-ray which showed that my hip was bone on bone. I scheduled surgery to have hip replacement, in November. It was a total success. I now walk limp free, no pain or discomfort of any type. The procedure he used was called anterior which was much quicker to recover. I am so grateful to Dr. Hernandez and his PA Mr. Montoya, plus the whole team. All were very professional and caring. I feel like I got my life back and can do all the things I used to do. - Dawn P.

"I am 65 years old and have always been very active, but eventually, the pain in both of my knees became unbearable. My husband just had hip replacement at SCOI under the care of Dr. Hernandez. We were so impressed with his care that I made an appointment. After talking with Dr. Hernandez, I knew I would be in very competent hands. He also relayed to me that I would have to have total knee replacement on both of my knees. In November 2013, I had my right knee replaced and was up and around after two weeks. I had no pain and was walking on my own after three weeks! I also had an issue with my hips, which caused them to be uneven and my walk to be unbalanced. Our goal then became, during my second total knee replacement, to correct that deformity as much as possible. This past July, I had total knee replacement of my left leg. By my second week and first follow up, I was walking on my own without a cane! My hips are aligned and I no longer look off balance. I love both of my new knees, and look forward to getting back on my bicycle. My quality of life has greatly improved, and I smile each time I see myself in the mirror!! There are no words of appreciation for the gift you have given me. I recommend Dr. Hernandez and his caring staff to anyone inquiring about hip or knee replacement. There are no better or more qualified place. Dr. Hernandez, you are my hero!" -- Karen M.

"Dr. Hernandez is amazing!  I had a total hip replacement on my right side.  He was very thorough when I met with him for the pre-op appointment to ensure that the correct size stem was used based on the size of my bones. He had encouraging words about what I'd be able to do after my surgery. In fact, his words repeated in my mind with any activity I engaged in after surgery. My surgery was performed at Northridge Hospital Medical Center. I received clear instructions on preparing for the day of surgery. After surgery, the hospital staff was fabulous as I was in recovery.  I recommend Dr. Hernandez to anyone who needs a hip replacement." -- Janine J.

"Just over a year ago, I was trying to get on my roof when the extension ladder I was climbing slipped under me and dropped me on my driveway.  Thanks to a friend's recommendation, I got a visit with Dr. Hernandez. I knew my hip was hurt, but he quickly noticed my wrist and brought his college Dr. Simic to investigate. The two of them worked all afternoon on the wrist to avoid emergency surgery, but after few hours, they realized I needed surgery quickly before the nerve died. Just after 10 pm that Friday night, Dr. Simic performed the first of the 4 surgeries I would receive from these two amazing men.

After going through the first hip rehab, with my wrist in a cast, and then the wrist rehab, I have a new appreciation for the therapists of the world, and especially, the ones at SCOI.  Every day they meet people who are hurt physically and mentally, and just when they get them fixed up, they have to say goodbye and hopefully for a long time. To say the least, I'm back in the shape I was in before the accident, running, biking, swimming, and working out just as hard as I did previously, but now with additional knowledge of how to stretch when I'm sore. As a thank you, I included all of them on my Christmas card list, and plan to continue, as I want them to know how I'm doing, thanks to their help." -- David D.
