Stem Cell and Platelet Procedures for Knee Injuries & Osteoarthritis

Regenexx Knee ProcedureRegenexx™ Stem Cell Procedures are breakthrough, non-surgical stem-cell treatments for people suffering from knee pain due to common injuries to the knee meniscus, ACL or MCL, cartilage, or who are experiencing degenerative conditions, such as osteoarthritis. Traditional options for patients suffering from these conditions include arthroscopic knee surgery to repair ligament tears, or total knee joint replacement. With both surgeries, months of rehab are required, and the patient must be aware of and prepared to take on the risks. As an alternative, the Regenexx-SD™ (same-day) procedure may help alleviate knee pain and the conditions that cause it with a simple office injection procedure.

  • Knee Function Improvement Data

    This data utilizes LEFS (Lower Extremity Functional Scale) data from our knee arthritis patients treated with stem cell injections. Functional questionnaires ask the patients questions such as how well they can walk, run, climb stairs, etc. The improvements following the Regenexx Stem Cell Procedure are highly statistically significant.

Knee Damage and the Regenexx-SD (Same-Day) Procedure

Stem Cells are in all of us and they are responsible for healing injured bone, ligaments, tendons and tissues. They are the key component behind the Regenexx Procedures. As we get older or injured, we sometimes cannot get enough of these cells into the area in need. The Regenexx Procedures help solve that problem by precisely delivering a high concentration of stem cells and growth factors into the injured area, aiding your body’s ability to heal naturally. Patients typically avoid the long, painful rehabilitation periods to restore joint strength and mobility following surgery. Regenexx patients are usually encouraged to walk the same day, and most experience little or no down-time from the procedure.

Millions Introduced to Regenexx Stem Cell Procedures on Television’s The Doctors

Regenexx Procedures were recently featured on “The Doctors” TV show. The episode featured Dr. Christopher J. Centeno and Dr. Ron Hanson from the Centeno-Schultz Clinic in Colorado, along with patient Barbee James, who sought stem cell treatment following traditional knee surgery. The 6 minute video provides a nice overview of the Regenexx-SD (Same Day) Stem Cell procedure

NBC TV Tells a Patient’s Story Following a Regenexx Same-Day Knee Stem Cell Injection Procedure

Seattle King TV recently featured Regenexx patient Paul Lyon in this news segment. Lyon chose to undergo a Regenexx-SD knee procedure, rather than an invasive and traumatic knee joint replacement surgery. The story looks at his results and includes an interview with Dr. Christopher Centeno, founder of the Regenexx Procedures.

Procedure ExplainedRegenexx-SD Procedure Overview

The Regenexx-SD procedure begins when the doctor thoroughly numbs the back of the hip (PSIS) and takes a small bone marrow sample through a needle, as well as a blood draw from a vein in the arm. The marrow is rich in Mesenchymal Stem Cells, which are responsible for healing damaged tissues. The stems cells are isolated from the marrow sample and platelets are isolated from the blood sample. After preparation, these two components will be reinjected directly into the damaged area of the joint using advanced imaging guidance. This ensures the cells are delivered to the exact location of need.
