The Regenexx Family of Procedures

In 2011, Derrington Orthopedics – Interventional Sports and Spine became the first west-coast clinic licensed and trained to perform the Regenexx® family of stem cell and platelet procedures at our headquarters in Oceanside, CA. Since then, we’ve opened another California location in the Orange County area. We’re now Regenexx® most active and experienced providers on the West Coast and have patients who have traveled from around the world to be treated by our highly-trained doctors.

These advanced stem cell and blood platelet procedures provide non-surgical treatment options for those suffering from joint or bone pain, torn or strained tendons and ligaments, or other common injuries and degenerative conditions. Regenexx procedures offer a viable alternative for patients with chronic pain and who may be considering surgery.

Your Alternative to Orthopedic Surgery

Regenexx uses your body's natural healing ability to repair damage to bones, muscles, cartilage, tendons, and ligaments non-surgically. Our proprietary, research-driven techniques allow us to concentrate your cells and to place them in the precise area of your injury to promote healing and to achieve optimal outcomes.

Regenexx Results

Since 2005 we have conducted research, accumulated patient results data and obtained direct feedback from our patients with one purpose in mind—to help you make an informed, confident decision to treat your condition.

Stem Cell Treatments

Same Day Stem Cell Protocol
Adult stem cells are cells from your own body that can renew themselves and turn into other cells (differentiate). They live inside all of us in various tissues, poised to leap into action to repair damage as it occurs. As we age or have big injuries, we may not be able to recruit enough of these cells to the site to fully repair the area. Regenexx Stem Cell Procedures help overcome this problem by extracting stem cells from an area of high volume, then concentrating the cells and reinjecting them into the damaged area to help the body heal naturally. Our Patented Stem Cell Procedures can be used for a wide range of conditions and are the tool of choice for injuries, arthritis and other conditions that may be more significant than what may be treated with our Platelet Rich Plasma or Platelet Lysate Procedures.

Blood Platelet Treatments

Super Concentrated Platelet Rich Plasma & Advanced Platelet Lysate Procedures
Platelet Rich Plasma (PRP) and Platelet Lysate Injection Treatments contain healing growth components from your own blood that increase your body’s natural ability to repair itself. The use of PRP to repair joint, tendon, ligament, and muscle injuries is becoming well known, thanks to exposure from professional athletes. Platelet injection treatments are effective because they have a stimulating effect on the stem cells within the targeted area, making those stem cells work harder to heal damaged tissues. Our Advanced Platelet Procedures are more pure and concentrated than those created by the automated machines used at most regenerative medicine clinics. Platelet procedures are commonly used for soft tissue injuries, mild arthritis and spine conditions.

Sports Medicine

Top Sports Medicine Doctors in the San Diego & Orange County Areas

The term Sports Medicine is used by health care professionals in a wide range of medical and holistic fields of study. Sports Medicine is sometimes claimed by chiropractors, massage therapists, personal trainers, orthopedic surgeons, athletic trainers and others as a specialty. While many of these positions do fall within the very large scope of treating elite athletes, weekend warriors and general physically active individuals of any age, the term Sports Medicine Specialist, uniquely defines Dr. Derrington's work.
