knee ACL stem cell research

There are so many clinics these past several years that have popped up after the physician took a weekend course and became a self-proclaimed stem cell expert. Being the first clinic in the U.S. to treat orthopedic patients with advanced stem cells, we’ve been able to lead that growing pack by innovating and perfecting what we do. Part of that process is publishing the research that everyone else can then try to emulate. Case in point this morning is our new knee ACL stem cell paper.

Let’s face it, knee ACL surgery is a scarred orthopedic surgery procedure that has really come to define modern orthopedic sports medicine. Not a week goes by without some high level professional athlete somewhere tearing an ACL and the sports media announcing that he or she needs surgery to “fix” the problem. However, what if most of the time the athlete didn’t need the surgery? What if the athlete could keep their natural ligament and avoid all of the major downtime and side effects of ripping out their natural ligament and trying to reconstruct an artificial one that will never be quite as good as the old one?

Our knee ACL stem cell research paper looks at the first 10 patients we ever treated. This was back when we thought that all we could treat was partially torn ligaments and as we were slowly learning that bigger complete tears could be treated as well. We’ve since treated many more patients that will be the subject of another upcoming paper. This study looked at before and after images using computerized imaging analysis to objectify if the post injection MRI looked better than the pre-procedure image.  We were able to objectively show evidence of healing in the vast majority of ligaments treated, all without surgery, but just an ultra-precise injection of the patient’s busted up ACL ligament with our unique protocol of same day stem cells.

The upshot? Based on what we routinely see everyday, we believe that about 70% of existing orthopedic surgery to reconstruct a torn ACL ligament will go away over the next 20 years. We also believe that the ability to get maximum healing with stem cell injections is directly tied to the precise image guided techniques we’ve perfected over the last several years with our Regenexx stem cell procedure for partial acl tears and full non-retracted tears. Now it’s time to continue to publish to continue to prove what we see in practice everyday, which is how we plan to change the world, one torn ACL at a time!

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

Hand & Wrist

Hand & Wrist

Hand and wrist injuries and arthritis, carpal tunnel syndrome, and conditions relating to overuse of the thumb, are good candidates for regenerative treatments. Before considering surgery, consider an evaluation of your condition with a regenerative treatment specialist.
  • Hand and Wrist Arthritis
  • Carpal Tunnel Syndrome
  • Trigger Finger
  • Thumb Arthritis (Basal Joint, CMC, Gamer’s Thumb, Texting Thumb)
  • Other conditions that cause pain

Elbow

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
