Dr. Arianjam is a Board Certified Orthopedic Surgeon who specializes in Sports Medicine, Arthroscopy, and Joint Replacements. He graduated as a Renaissance Scholar magna cum laude at the University of Southern California. He attended Keck School of Medicine at USC to finish his medical training before going to the San Francisco Orthopedic Residency Program. He then returned to Southern California to complete his surgical training with a fellowship in Orthopedic Sports Medicine at Kaiser Permanente Orange County. Throughout his career, his passion in sports medicine has led him to serve as team physician and provide care for various athletes in the Bay Area Orange County, and the High Desert. As part of his fellowship, he helped care for the Los Angeles Angels of Anaheim baseball team, as well as student athletes at the high school and university level. In addition to treating ligamentous and soft tissue injuries, he is well versed in the latest cartilage restoration techniques. He is certified to perform Autologous Chondrocyte Implantation (ACI) as well as cartilage transplantation procedures, and has experience with Platelet-Rich-Plasma (PRP) and viscosupplementation injections. As part of his continuum of care, when joint preservation options are exhausted, he is also adept at performing reconstructive surgeries and joint replacements.

Dr. Arianjam prides himself on his excellent bedside manner, attention to detail, and staying current with the latest research.

Many orthopedic injuries can be treated with nonsurgical remedies including physical rehabilitation exercises and medication. Dr. Arianjam helps guide and educate patients to make the right decision on their treatment.

As a native of Southern California, he is excited to be close to his childhood home and care for athletes and patients in his local community. Dr. Arianjam enjoys spending time with his growing family. He likes to stay active; his hobbies include hiking, biking, and playing recreational sports.

Research and Education

Dr. Arianjam has also performed considerable clinical research. Alongside one of the pioneers of shoulder arthroscopy, his work includes a 10-year follow­up study on the outcomes of the arthroscopic remplissage, a now widely-used procedure for shoulder instability. His most recent publication features work with a national community­-based ACL registry to identify which techniques give patients the best outcomes for Anterior Cruciate Ligament Reconstruction. He continuously strives to practice medicine and surgery with the most current evidence­-based literature.
