 Regenexx-C Patient testimonials

 Pixie Greenemier underwent the Regenexx-C procedure as an alternative to traditional knee surgery This is her Regenexx-C Patient testimonial:

“I’m a very active person – I snowboard, take conditioning and self-defense courses, and am always out doing something. I’m also a nurse at The Children’s Hospital in Denver, so I’m constantly on my feet, always moving around.”

“When my orthopedic doctor performed arthroscopic surgery on the knee, he was surprised at the amount of damage – I was basically down to bone-on-bone in the knee. He said that short of a total knee replacement, there weren’t any treatments that would help me.

I was doing a one-legged squat during one of my conditioning courses when I tore the meniscus in my right knee. After that, I was constantly in pain. My knee was swollen, and it got to where I couldn’t even get up from squatting down without having to pull myself up. I couldn’t do my self-defense and conditioning courses, and there was no way I could snowboard.

When my orthopedic doctor performed arthroscopic surgery on the knee, he was surprised at the amount of damage – I was basically down to bone-on-bone in the knee. He said that short of a total knee replacement, there weren’t any treatments that would help me.

At the same time, I had also been a patient of Dr. Centeno’s, and I found out about his cartilage regeneration procedure. My orthopedic surgeon encouraged me to try the procedure, so we went ahead with it in early 2007.

I was amazed at how quick, painless and non-debilitating the whole thing was. I had four bone marrow draws and two stem cell injections, with only a small bruise after any of the procedures. I was back on my feet one hour after each treatment. Even my co-nurses at the hospital couldn’t believe it.

Still more amazing, however, were the results. After the third week, the swelling was completely gone, and my knee actually looked like a knee again. We did an MRI a little while later and found 20 percent regeneration in the cartilage, so I asked if we could do another round of the procedure, which we did in June.

Now, I’m back to my conditioning classes, doing squats, lunges, jumping rope and even a little bit of jogging. My knee feels, looks and works better every day. I’m definitely looking forward to the winter and getting back on my snowboard as soon as I can.

I would recommend the Regenexx-C procedure in a heartbeat to anyone who’s dealing with joint injuries or osteoarthritis. It’s put me on track to getting my life back to where I want it.”

NOTE: This patient was treated with the Regenexx-C cultured stem cell injections and not Regenex SD.  Regenexx-C is a medical procedure and like all medical procedures has success and failure rates and therefore not every Regenexx-C knee patient can expect to this same result.

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

  • 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
