Sumit H. Rana, MD


Dr. Sumit H. Rana is a board-certified and fellowship-trained Orthopaedic Surgeon.  His practice is focused on hip and knee replacement surgery, including: partial and total knee replacements, anterior and posterior hip replacements, knee arthroscopy, orthopaedic trauma and fracture care, and revising hip and knee replacements that have failed.  He is best known for his excellent bedside manner, ability to listen to his patients’ needs and concerns, keen attention to details, and superior surgical skills and outcomes.

He was raised in Diamond Bar and attended Webb High School; where he played soccer, ran track and field, and graduated top of his class. For college, he was selected into the ultracompetitive Baccalaureate/MD Program at the University of Southern California, where out of thousands of college applicants, only twenty are chosen and granted admission to the medical school based on their high school achievements. He was also the recipient of the Trustee Scholarship, which is a merit-based academic scholarship that provides for the recipient’s full-tuition. During undergrad, he continued to receive multiple awards and honors such as the USC Renaissance Scholar award, and induction into Phi Kappa Phi and Kappa Beta Honor Societies. He graduated magna cum laude with a major in Biology and a minor in Business Administration in 2004. He then matriculated to the University of Southern California – Keck School of Medicine where he was elected into the prestigious Alpha Omega Alpha Honor Society and graduated with “Highest Distinction” – the highest award bestowed at graduation – in 2008. While in medical school, he became interested in orthopedic surgery.

After medical school, Dr. Rana got into his top choice for residency and completed his orthopedic surgery training at the University of California – San Diego. He enjoyed all aspects of orthopedics, and performed cutting-edge orthopedic research that culminated in several orthopedic journal publications and presentations at the national level.

While in residency at UC San Diego, Dr. Rana developed an interest in innovative techniques for managing hip and knee arthritis, and he went on to complete a fellowship specializing in joint reconstruction at Stanford University. During his fellowship, Dr. Rana also served as a clinical instructor at Stanford University training orthopaedic residents and medical students. At Stanford, his training focused on primary and revision hip and knee replacement surgery. This comprehensive training also included exposure to partial knee replacements, computer navigated joint replacements, patient-specific knee replacements, biologic replacement, and minimally invasive anterior hip replacements. Through Dr. Rana’s technical skill and postoperative pain protocols, his patients are able to notably leave the hospital sooner and recover quicker than other patients undergoing these same procedures.

Dr. Rana is familiar with the most recent advances in hip and knee replacement surgery as well as conservative, non-surgical management of hip and knee problems. His goal is to provide compassionate and evidenced-based care for his patients, and his motto is to treat every patient as if he or she were a family member. Nothing gives him more satisfaction than to help patients overcome a debilitating condition, improve their quality of life, and regain their mobility. He is grateful for the opportunity to work in the Los Angeles and Ventura Counties and provide care for the patients and families in these communities. He lives in Agoura Hills with his wife and two children, and in his spare time he enjoys travelling, trying new foods, hiking, snowboarding, and relaxing with his family.
