A new Hip Impingement Arthroscopy Research Paper calls into question the whole concept behind the surgery…

We’ve been critics of what we call, “Hip Arthroscopy Mania”. Basically, most commonly, a bone spur is detected on the outside (lateral) portion of the socket (acetabulum) of the ball and socket joint of the hip. The story goes that this bone spur can impinge on the ball (femoral head) and hurt the cartilage, leading to arthritis. This has lead to a new surgical approach this past decade where the bone spur is taken off surgically, hopefully protecting the cartilage. All of this was based on some studies that showed that patients with these bone spurs had more arthritis. What we didn’t know was what came first, the chicken or the egg? Meaning did the bone spur form because of the arthritis or was the bone spur the cause of the arthritis. The only way to answer this was not to do more snapshot studies of whether people with arthritis have the bone spurs, but to follow people with mild arthritis while they developed the spurs.

An innovative group of physicians just did this in Norway and what they found isn’t good for concept of whacking off these hip bone spurs through hip arthroscopy. They basically found that the bone spurs formed because of the arthritis and may be protective of the arthritis becoming more severe. This fits with what I’ve discussed previously about bone spurs. These spurs are good and they protect the joint, so taking them off is likely a bad idea.

The upshot? IMHO Hip arthroscopy mania is just that, lots of surgery, much of which isn’t helping patients nor well thought out. I guess the only good news for hip arthroscopy surgeons out of this recent Hip Impingement Arthroscopy Research Paper is that patients who have a short socket (hip dysplasia) do develop arthritis that seems to be from the small socket. What we don’t know yet, with high levels of evidence, is if reshaping the socket to be bigger saves this type of joint from arthritis.

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
