Prem N Ramkumar, M.D.

Biography

Prem N Ramkumar, M.D. MBA is a dual fellowship trained orthopaedic 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 orthopaedic 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 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 orthopaedic 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 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 orthopaedic hip and knee conditions from medical, socioeconomic, political, and technologic 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 9 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 orthopaedic patents, contributed to multiple design teams for novel implants and technologies sponsored by industry-leading orthopaedic manufacturers, and established the world’s first laboratory dedicated to evaluating the applications of artificial intelligence in orthopaedic 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.
