Autologous conditioned serum, also known as Orthokine and Regenokine, is an experimental procedure in which a person's own blood is extracted, manipulated, and then reintroduced with claimed benefit in osteoarthritis.[1] There is limited evidence on safety and effectiveness as of 2017,[1] it is not included in medical guidelines as of 2017.[1] It is a type of autologous blood therapy.[1]

Medical use[edit]

There is limited evidence on safety and effectiveness as of 2017.[1] There is tentative evidence in osteoarthritis,[2] its use has not been recommended or considered by the Osteoarthritis Research Society International.[1]

Process[edit]

The process removes about 2 US fluid ounces (59 ml) of blood from a patient's arm, which is then incubated at a slightly raised temperature.[citation needed] The liquid is then placed in a centrifuge until its constituent parts are separated; that serum is injected into the patient's affected area.

History[edit]

Autologous conditioned serum is a patented method developed by molecular biologist Julio Reinecke and Peter Wehling, a spinal surgeon in Düsseldorf, Germany.[3][4] Orthokine was first approved for use in Germany in 2003.[5] Orthokine differs from a similar procedure with platelet-rich plasma (PRP),[6] where platelets are targeted instead of the interleukin antagonist. Also, PRP does not require the blood to be heated as Orthokine does.[citation needed]

As of August 2012, about 60,000 patients worldwide have received the treatment.[5] Americans have traveled to Germany for the treatment, which has not been approved by the U.S. Food and Drug Administration (FDA).[7][4] Freddie Fu, a professor of orthopedic surgery at the University of Pittsburgh, said more high-quality independent trials proving the procedure's effectiveness are needed before the FDA approves. National Basketball Association player Kobe Bryant traveled to Germany to have the procedure performed;[7][3] some basketball fans refer to the procedure as the "Kobe Procedure".[3]

The procedure cost €6,000 (about $7,400) as of July 2012; the treatment is not covered by health insurance.
