Explaining Why Regenexx is Very Different

by Chris Centeno, MD /

This week I spoke to a patient who had a bone marrow procedure at a non-Regenexx clinic in Texas and it had failed. She knew that what we did was different, but wanted to know exactly how. Hence, this blog.

An Overview of Why What We Do is Different

You can break what we do differently into four parts:

  1. The harvest
  2. The processing
  3. Dosing
  4. The protocol and placement

I’ll go into depth on each one, but you can also watch my video for an overview:

The Harvest

A bone marrow aspiration begins a bone marrow stem cell procedure. This is where the doctor takes a specialized needle and withdraws what looks like thick blood (called bone marrow aspirate or the liquid portion of the bone marrow) from the back of the patient’s pelvis. As long as the area is numbed correctly, the patient doesn’t feel that much.

This patient’s doctor in Texas used an ultrasound to draw from a single site and a single side of the patient’s pelvis. Why is this a problem? This type of draw reduces the number of stem cells in the sample. Why? The bone marrow space communicates with the rest of the vascular system, so only the first few ml’s of the draw actually contain many stem cells and the rest is blood with no stem cells.

How do we do this? We take smaller volumes from more sites that increase the stem cell yield. It takes longer and is more work for the doctor, but it’s better for the patient’s procedure. For more information on this topic, see my video below:

The Processing

After bone marrow is drawn, it’s concentrated via a centrifuge. The goal is to select out the fraction of the bone marrow containing stem cells. Most of the time this is done with simple bedside machines that are not all that efficient. In fact, this woman’s doctor used one of these machines.

The problem? The extent of knowledge that the doctor has about what’s happening is where to put the bone marrow and where the “On” button is located. What do we do differently? We use a Flexible Lab Platform that’s capable of a much better isolation of this fraction. In addition, we add in additional stem cell sources from the bone marrow that these simple bedside machines throw away. The result? More stem cells. See my video below for more information:

Dosing

While this might sound insane, these little bedside machines don’t tell you how many cells you have. So while it would be malpractice in any other field of medicine to inject something without knowing the dose, in stem cell procedures, it’s par for the course. The clinic this woman went to didn’t know the dose. This turned out to be a big problem. Why?

The patient had knee arthritis treated on both sides. The issue? Our published knee arthritis dosing paper showed that she needed a minimum of 400M total nucleated cells per knee. However, in her age range, there’s only a 1 in 4 chance of having that cell number. Hence, there’s a 3 in 4 chance that she was underdosed.

Below is a video on why the correct dose is critical in these procedures:

The Procedure and Protocol

What you do with the cells once you have them is critical. In order to decide where they go you begin with an advanced and time-consuming exam. For example, should they be injected into the medial or lateral side? Does a loose MCL or ACL or meniscus need to be targeted to provide stability? Does a bone marrow lesion need to be treated by injecting precisely into the bone with x-ray guidance? Is there also a simmering low back problem that also needs to be treated to get the best results?

In this woman’s case, only a simple ultrasound-guided “inside the joint” (intra-articular) injection was performed. This could be an issue as a review of her MRI shows a likely lax ACL and MCL, both not treated. In addition, we have a three-part patented protocol that involves a pre-injection (till the soil), stem cell injection (plant the seeds), and post-injection (fertilize).

For more information about how precise targeting is very different than the type of simple injection is this woman received, see my video below:

The upshot? I invented this space and the concept of knee intra-articular stem cell procedures. However, as you can see, the “real deal”, is vastly different than the imitation. This Texas doctor learned from someone who learned from someone who learned from someone who learned from us. However, regrettably much was lost in the translation.

    What about tiger woods ? With peyton manning that is 2 who are doing well… not suppose to happen… missing something ?

    1. Regenexx Team

      stef,
      Time…

    2. Dr Matthew Hyzy

      Tiger woods is not doing well
      He had multitude of back surgeries

      Peyton Manning also had cervical surgery with augmentation of a different growth factor than Prp and it was not bone marrow stem cells

      Thanks for your reply and reference the blog for the difference between a thorough evaluation and treatment by a Regenexx doctor VS a sophomoric approach to treatment which is what this blog is discussing and educating

Regenerative procedures are commonly used to treat musculoskelatal trauma, overuse injuries, and degenerative issues, including failed surgeries.
Select Your Problem Area
Shoulder

Shoulder

Many Shoulder and Rotator Cuff injuries are good candidates for regenerative treatments. Before considering shoulder arthroscopy or shoulder replacement, consider an evaluation of your condition with a regenerative treatment specialist.

  • Rotator Cuff Tears and Tendinitis
  • Shoulder Instability
  • SLAP Tear / Labral Tears
  • Shoulder Arthritis
  • Other Degenerative Conditions & Overuse Injuries

Cervical Spine

Spine

Many spine injuries and degenerative conditions are good candidates for regenerative treatments and there are a number of studies showing promising results in treating a wide range of spine problems. Spine surgery should be a last resort for anyone, due to the cascade of negative effects it can have on the areas surrounding the surgery. And epidural steroid injections are problematic due to their long-term negative impact on bone density.

  • Herniated, Bulging, Protruding Discs
  • Degenerative Disc Disease
  • SI Joint Syndrome
  • Sciatica
  • Pinched Nerves and General Back Pain
  • And more

Knee

Knees

Knees are the target of many common sports injuries. Sadly, they are also the target of a number of surgeries that research has frequently shown to be ineffective or minimally effective. Knee arthritis can also be a common cause for aging athletes to abandon the sports and activities they love. Regenerative procedures can be used to treat a wide range of knee injuries and conditions. They can even be used to reduce pain and delay knee replacement for more severe arthritis.

  • Knee Meniscus Tears
  • Knee ACL Tears
  • Knee Instability
  • Knee Osteoarthritis
  • Other Knee Ligaments / Tendons & Overuse Injuries
  • And more

Elbow

Most injuries of the elbow’s tendons and ligaments, as well as arthritis, can be treated non-surgically with regenerative procedures.

  • Golfer’s elbow & Tennis elbow
  • Arthritis
  • Ulnar collateral ligament wear (common in baseball pitchers)
  • And more

Hip

Hip

Hip injuries and degenerative conditions become more common with age. Do to the nature of the joint, it’s not quite as easy to injure as a knee, but it can take a beating and pain often develops over time. Whether a hip condition is acute or degenerative, regenerative procedures can help reduce pain and may help heal injured tissue, without the complications of invasive surgical hip procedures.

  • Labral Tear
  • Hip Arthritis
  • Hip Bursitis
  • Hip Sprain, Tendonitis or Inflammation
  • Hip Instability

Foot & Ankle

Foot & Ankle

Foot and ankle injuries are common in athletes. These injuries can often benefit from non-surgical regenerative treatments. Before considering surgery, consider an evaluation of your condition with a regenerative treatment specialist.
  • Ankle Arthritis
  • Plantar fasciitis
  • Ligament sprains or tears
  • Other conditions that cause pain
