About Dr. Marumoto

Jay M. Marumoto, M.D. is a Board Certified orthopedic surgeon, specialty-trained in Arthroscopic Surgery & Sports Medicine.  Dr. Marumoto completed this specialty training at the Southern California Orthopedic Institute (www.scoi.com), regarded as the premiere center in the U.S. for innovative techniques in Arthroscopic Surgery.

Arthroscopic Surgery is a "minimally-invasive" technique that utilizes tiny incisions (usually 1/4 to 1/2 inch), fiber-optic camera-scopes, and miniature instruments to repair and reconstruct damaged cartilage, tendons, and ligaments. Dr. Marumoto's training allows him to use "Advanced" techniques that involve "intra-articular suturing," (sewing and knot-tying) within the confines of the joint without the need for "open" incisions.

Dr. Marumoto also completed specialty training in Reconstructive-Fracture Surgery in Switzerland at the AO institute's Davos Hospital (www.ao-asif.ch).

Academically, Dr. Marumoto is an Assistant Clinical Professor of Orthopedic Surgery at the University of Hawaii. He has published medical research and continues to lecture nationally and locally on injuries of the ACL, meniscal cartilages, rotator cuff, shoulder dislocations, ankle cartilage and ligaments, Achilles tendon, elbow ligaments, and many other sports injuries.

Never far from sports, Dr. Marumoto can be found on the sidelines as the Team Doctor for the University of Hawaii Football team..

Dr. Marumoto is a local boy, born and raised in Honolulu.  His late grandfather, former Supreme Court Justice Masaji Marumoto, and his mother, State Representative Barbara Marumoto, have built strong roots in the local community that Dr. Marumoto is proud to hail from.
