Putting in a Thumbtack with a Sledgehammer

A new Regenexx-C procedure patient illustrates a major problem in our medical care system.  This is a 47 year old triathlete who has had 7 years of back and knee pain.  She was diagnosed with patellar tendinitis on the right greater than left side.  Her MRI showed significant cartilage loss on the medial side of the patello-femoral joint and significant medial soft-tissue and tendon swelling.  Since there was a patellar tendon issue, the Quadriceps muscle should have been looked at as a cause of this problem.  However, instead, a surgeon opened the area above the tendon and “scored” these swollen areas with a scalpel.  This has now caused new scar tissue which restricts the lateral travel of the knee cap, thus more severely overloading the medial side (the side that had the problem before the surgery).  Her pain has gotten worse and since her whole social life revolves around triathlons, this has affected more than her ability to exercise.

First, if the tissue needed to be tightened, there are many ways to do this that don’t involve open surgery.  This could be accomplished via needle with prolotherapy or even procedures similar to thermal capsulorraphy.  Why would someone take this “putting a tack in with a sledgehammer approach”?  This type of musculoskeletal realignment surgery (such as lateral knee fascial releases) originated with very valuable surgeries on children with severe spasticity.  These kids are generally unable to walk and cutting a structure here or tightening something there can really allow them to become more functional.  In those kids, it doesn’t matter if the healing of the area is “spot on”.  Their little bodies are generally so misaligned that even if the surgery heals with a precision of a 1/2″ (cm), no big deal.  However, in a finely tuned athlete like this one, a few millimeters (1/16-1/32 of an inch) makes a  huge difference.  In these cases healing with an accuracy of 1/2″ is a big problem.

How can we help at this point?  Good question.  While we can likely help the cartilage on the medial side of the patello-femoral joint by injecting her own culture expanded stem cells, the issue is now the much greater force on that side created by the surgery.  I’ve asked her to have a physical therapist try to regain the lost lateral travel of the patella so she can return to normal patello-femoral travel.

In summary, while knee realignment surgery can make a dramatic positive impact in kids with CP and other diseases where tight muscles cause severe functional problems, relying on big surgical procedures to realign the knees of athletes is fraught with difficulties.  In other words, putting in thumbtacks with sledgehammers is generally ill advised.

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

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
