If you read this blog, you have seen that we now have gobs of high-level evidence showing that surgery for the vast majority of meniscus tears in middle-aged patients is a fool’s errand. Despite this, the procedure is still the most common elective orthopedic surgery in the U.S. Now we have brand-new research that also weighs in on this controversial procedure and again finds that it’s no better than physical therapy.

The History of Meniscus Surgery Research

The first sign that meniscus surgery was a lark happened way back in 2002, when a study by a university orthopedic surgeon showed that debridement (the cleaning up of a knee that has arthritis and degenerative meniscus tears) was no better than a sham surgery. After that study, many orthopedic surgeons published nasty comments that equated to a desire to blow up the poor guy’s car. However, over the ensuing years, the procedure slowly slipped into the dustbin of medical history.

The next study came from an interesting source: the same small town in Massachusetts that had given us so much data about heart health. The Framingham osteoarthritis study concluded meniscus tears didn’t hurt and were as common in middle and older ages as wrinkles and about as important. Now things were getting really interesting…

In 2012 a level-1 research study published in the prestigious New England Journal of Medicine showed that meniscus tear patients who had partial meniscectomy surgery didn’t have any better outcomes than those who didn’t have the surgery and just went through physical therapy. Many orthopedic surgeons dismissed the research by arguing that these patients had some arthritis as they felt that there was still a rationale for operating on patients with a meniscus tear who didn’t have arthritis. That all evaporated in 2013 when a level-1 study demonstrated that meniscus surgery in patients with no arthritis was no better than a placebo surgical procedure. The one condition left that surgeons were sure would be a no-brainer for surgery was a knee that was locking due to a meniscus tear. The bubble burst with a study out of Finland that compared mechanical locking patients who had the surgery versus those who did not. The new study again concluded that the procedure was ineffective.

A Newer Study Is Published

The study (again out of Finland) begins with an interesting statement of frustration:

“Despite recent studies suggesting arthroscopic partial meniscectomy (APM) is not more effective than physical therapy (PT), the procedure is still frequently performed in patients with meniscal tears.”

This new research included more than 300 patients in nine hospitals who had been diagnosed with meniscus tears after age 45. About half the patients were randomized to partial meniscectomy and half to eight weeks of physical therapy. Not surprisingly, once all of the data was crunched, the procedure turned out to be no more effective than physical therapy. This is a really nicely done summary by JAMA:

Given the above research over almost two decades, the result of this new study is not a shocker. In fact, with this study added, we now have four high-level randomized controlled trials that show the procedure doesn’t work. Why is it still very common? If it went away tomorrow, most orthopedic surgeons and hospitals wouldn’t be able to make payroll. It’s as simple as that.

What are the alternatives? Can a knee meniscus tear be treated without surgery if physical therapy doesn’t help? Read my book below to find out (click on the picture):

The upshot? Why are we still offering this procedure to patients? Your guess is as good as mine. Having said that, it’s time to start phasing this out. My guess is that we’re a year or two away from most national health systems deciding not to cover it and three to four years away from American insurers only covering it on a case-by-case basis. So if you’re over 35–45 and have knee pain and have been told you have a meniscus tear and your doctor tells you need this surgery, without a complete discussion that it has been shown to be ineffective, please politely say no and never return to that office!

    What are your thoughts on mpfl reconstruction for a knee instability problem? The Dr. suggested this procedure for my son b/c of knee subluxation issues. She also mentioned TTT surgery at the same time. I’m only leaning toward mpfl at this time- she would use his hamstring tendon to create new ligament. He’s 20. I’m so confused and overwhelmed. He’s going to start physical therapy first. This is an HSS surgeon so I’m trusting her knowledge.

      Melanie,
      We would not recommend these surgeries until less invasive options have been ruled out. We’d need more information through a Candidacy evaluation, but this is likely treatable without the long term bio-mechanical consequences of these surgeries. To do that, please submit the Candidate form, or call 855 622 7838

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 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)

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
