Can a knee stem cell injection help a severely degenerated knee?  DS is a 50 year old woman who was first seen in April of 2011 for knee pain on both sides. In the early 90’s she had a torn ACL with a second tear in her meniscus and underwent surgery to treat both areas. She then needed a second arthroscopy to clean out the scarring from the first arthroscopy. After that she did well until about 2006 when she fell cross county skiing and had another cartilage tear and a third knee surgery. 3 months later she twisted her knee suddenly and had more cartilage tearing and was debrided again. Since then, for the preceeding 4 years before seeing us, she was in pain that prevented many activities. At that point she also suffered from recurrent swelling with anything more than flat walking. Dr. Hanson diagnosed her with an extruded meniscus which was also small from multiple surgical debridements. In addition she also had a lax ACL, patellar tendinosis, and a degenerated MCL. In April of 2011 she underwent the Regenexx-SCP procedure for the ligaments and tendons, -SD for the “good” knee where she had patellar chondromalacia, and a Regenexx-AD procedure for the extruded meniscus. Three months later she had another twisting episode and a set back that required a second round of treatments. So how is she doing at more than a year out form the second treatment? Her words below:

 “My knees are doing awesome!!  I haven’t had any lt. knee pain for 2 mo. now.  I still get occasional pain in my rt. knee laterally – especially after walking on rough terrain (like the lava fields).  But I still feel my rt. knee is 90% improved.  I am rating my lt. knee at 95% improvement – if the lack of pain continues for the next few months I will bump that up to 100%.  I am biking without any pain in either knee which is wonderful!

The upshot? Despite not being a good candidate and having multiple failed knee surgeries, an injection of her own same day stem cells seems to have done the trick for DS. We can’t rule out that she might not need update treatments and not everyone in DS’s state of knee disrepair can expect a result like hers. However, I’m quite sure she would have had little result without Dr. Hanson’s expert ability to diagnose multiple complex issues and treat those with various technologies through specific guided injections.

NOTE:  Regenexx-SD, Regenexx-AD and Regenexx-SCP are medical procedures and like all medical procedures have a success and failure rate.  Not all patients experience the 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

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
