Southern California Orthopedic Knee & Hip Specialist

Orange County • Los Angeles • Long Beach

Prem N. Ramkumar MD, MBA is a dual fellowship trained orthopedic surgeon with focused expertise in hip and knee conditions. He treats Southern California and traveling patients at Long Beach Lakewood Orthopedic Institute. 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.

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. Since he first began studying the biomechanics and material properties of modern total hip replacements at the age of 12, his commitment and passion for studying the hip and knee has only exponentially grown. As a result of his extensive analysis of the impact of orthopedic hip and knee conditions from medical, socioeconomic, political, and technologic perspectives, Dr. Ramkumar is renowned as both a clinician-scientist and editorial columnist.
