David Eldringhoff, MD, is a leader in sports medicine, hip, knee, and shoulder surgery, and the care of the injured athlete. He is skilled in orthopedic surgery and cares for patients in the Los Angeles area at Samimi Orthopedic Group in Brentwood, West Covina, and Sherman Oaks, California.
Dr. Eldringhoff was raised in Kansas City, Kansas. He attended Kansas State University, where he received a Bachelor of Science in 2008 with a major in chemistry and minors in physics and microbiology. He received his medical degree from the University of Kansas School of Medicine in 2012. Dr. Eldringhoff completed a residency in orthopedic surgery at Saint Louis University Hospital in Missouri.
He then completed a sports medicine fellowship at Congress Orthopaedic Associates in Pasadena, California. His fellowship focused on the treatment of injuries to the hip, knee, shoulder, and elbow, with a special emphasis on minimally invasive arthroscopic treatment. During his fellowship, Dr. Eldringhoff provided sports-related care for Occidental College, Pasadena City College, and several local high school football teams.
Dr. Eldringhoff has extensive and specialized training in orthopedic surgery, joint replacements, fracture care, sports medicine, and hip arthroscopy. His emphasis is on arthroscopic and open surgery of the hip, shoulder, elbow, and knee.
He has a unique interest in arthroscopic treatment of hip pathology that may one day be shown to prevent or delay the onset of hip arthritis in adolescent, young adult, and adult hips. Dr. Eldringhoff addresses hip impingement and labral tears with arthroscopic labral repair, using bioabsorbable bone anchors similar to those used in shoulder surgery. He also removes the bony abnormalities associated with this condition entirely through the arthroscope.
Dr. Eldringhoff also performs total joint replacement for patients with advanced hip, shoulder, and knee arthritis that cannot be treated with arthroscopy. For hip replacements, he utilizes the newest anterior approach, improving post-operative pain and providing quicker recovery.
Throughout his academic career, Dr. Eldringhoff has had substantial involvement in orthopedic research. Specific projects have focused on advances in tibial plateau fracture treatment, cartilage regeneration, and arthroscopic surgical efficiency.

Dr. K repeatedly asked if I had questions, we chatted and he listend to what I had to say. I was able to get an injection immediately as opposed to having to wait 3 months with the other doctor. I feel that this relationship will be good.”

Message from Dr. Mora
"I hope to create a close patient-doctor relationship based on trust and mutual respect. I believe my patients’ medical treatment begins with their complete understanding of their condition, and I promise to do my very best to understand the cause of your pain and then provide a treatment approach that is tailored to meet your specific needs.
I believe that my success in diagnosing and treating orthopedic problems was borne out of my own personal traumatic injury to my legs. While living in Peru, I was struck by a commuter bus, severely injuring my legs and forever changing my life. I have experienced many of the same surgeries that I now perform on my own patients — and I believe this experience has allowed me to be more in tune with my patients’ concerns, symptoms and experiences.
My family heritage is Peruvian and I speak fluent Spanish."
