Prem N Ramkumar, MD, MBA is a dual fellowship-trained orthopedic surgeon with focused expertise in hip and knee conditions, from sports medicine & arthroscopy to joint replacement & adult reconstruction. Dr. Ramkumar is proud to serve his hometown counties of Los Angeles and Orange County.

Education

He received his medical education and surgical training at Cleveland Clinic, Harvard/Brigham and Women’s Hospital, and Hospital for Special Surgery – the #1 ranked orthopedic hospital in the country. He was privileged to serve as Assistant Team Physician to the NBA’s Brooklyn Nets and MLS’ Red Bulls during his time at Hospital for Special Surgery.

He acquired his MBA from Cornell University’s campus at Cornell Tech campus in New York City to continue leveraging emerging technologies to improve the clinical practice of hip and knee conditions. Specifically, his research team is currently evaluating the impact of a combined deep learning, computer vision, and segmentation algorithm to automate the detection and quantification of abnormal hip and knee anatomy with preoperative CT scans.

Medical Approach

Dr. Ramkumar’s core value is caring for patients. He does so by treating his patients like he would his own family, listening to them, and understanding their priorities in life. In return, Dr. Ramkumar will always be transparent about the realities and evidence surrounding a patient’s underlying condition and treatment options.

It is not common for orthopedic surgeons to be dual fellowship trained. Dr. Ramkumar specifically chose to pursue two hip and knee fellowships to be a comprehensive, one-stop shop for any patient with a hip or knee condition – from arthroscopy and repair to resurfacing and replacement. He appreciates the difficulty of navigating the world of healthcare and finding access to the right doctor who can actually help. His patient-centered and dual-training focus on the hip and knee affords him the ability to expand his medical and surgical “toolbox” to more finely tailor the treatment plan to the patient’s specific problem and personal goals.

Specialties

Dr. Ramkumar has expertise in the following surgical procedures: hip arthroscopy, hip resurfacing, ACL reconstruction, cartilage repair, knee osteotomy, partial knee replacement, total knee replacement, total hip replacement, revision joint replacement, robotic joint replacement, direct anterior hip replacement.

Beyond clinical expertise, Dr. Ramkumar is renowned as both a clinician-scientist and editorial columnist. In both capacities, he has extensively analyzed and described the impact of orthopedic hip and knee conditions from medical, socioeconomic, political, and technological perspectives. Since he first began studying the biomechanics and material properties of modern total hip replacements at the age of 12 at Los Angeles Orthopaedic Hospital, Dr. Ramkumar’s commitment and passion for studying the hip and knee has only exponentially grown.

Awards & Recognitions

To date, he has authored 124 peer-reviewed publications, written 11 textbook chapters, published nine articles in Forbes (among other circulations), received four institutional grants, lectured nationally and internationally on over 40 occasions, served on the editorial board for the Journal of Arthroplasty, reviewed for every major hip and knee journal (Journal of Bone and Joint Surgery, American Journal of Sports Medicine, Bone and Joint Journal, Arthroscopy, Journal of Arthroplasty), won national awards for his commitment to research and policy from both the American Orthopaedic Society for Sports Medicine and the American Association of Hip and Knee Surgeons, holds three orthopedic patents, contributed to multiple design teams for novel implants and technologies sponsored by industry-leading orthopedic manufacturers, and established the world’s first laboratory dedicated to evaluating the applications of artificial intelligence in orthopedic surgery.

When he is not in the office or the operating room, Dr. Ramkumar enjoys being a full-time father (girl dad and dog dad), husband, and unabashed Lakers fan. As a former nationally ranked collegiate tennis player, he enjoys recreational sports and is particularly excited to be back home exploring the beautiful outdoors our great state has to offer.

Testimonials

The patient perspective

Check out what Dr. Ramkumar’s patients have to say about their treatment experiences and results.

Dr. Ramkumar walked into my room with his hand out and said ‘Hi, Coral. I’m Prem’… After that humble introduction, I knew I was in the right hands for this hip replacement! For the first time in 4 years, I can walk without a cane and I have no pain. I even had a first being able to stand up straight at an x-ray machine. I cried and shared that with him.
Coral October 2024
The first time I met Dr. Ramkumar, I felt comfortable and at ease. I came to him with “knee pain” but after being assessed and taking a few x-rays, he quickly informed me that the issue was not my knee but was actually my hip. My experience with him has been nothing short of amazing…The hip impingement surgery went well and recovery was better than I expected…

Dr. Ramkumar performed a total left knee reconstruction on my mom one month ago. He was very professional by explaining it was a high risk complicated surgery due to her diabetes. Thankfully everything went well and my mom is healing good day by day. We are very pleased of Dr. Ramkumar’s amazing, skilled and dedicated work! Definitely recommend!
Adrian R September 2024
I am fortunate to have Dr. Prem Ramkumar as my orthopedic surgeon. He accurately diagnosed my issue and was successful in surgically repairing it… After my five years of severe pain, during which I incurred multiple surgeries, shots, and pain pills, I am finally back to my active lifestyle. I am also impressed by how nice his office is and the professionalism of his staff.
Glenn G September 2024
After several doctors could not figure out my history of symptoms and pain, I went to Dr. Prem N Ramkumar, who took the time to discover this rare and unique condition I had been living with. Over the years, I gave my blood, sweat, and tears to this injury. I highly recommend Dr. Prem N Ramkumar to anyone needing Ischiofermoral Impingement decompression and sciatic neuroplasty surgery; I cannot speak highly enough of his and his staff’s care.
