Why It’s Time to Rethink Arthroscopy Shoulder Surgery

On this page:

Arthroscopy shoulder surgery is a common way shoulder injuries are treated. However, since there are significant side effects, do you really need this surgery? These days, precise injections of your own platelets or stem cells are likely to be able to help without surgery. So let’s review.

Arthroscopy Shoulder Surgery

Arthroscopy shoulder surgery is pushed as a less invasive alternative to open shoulder surgery. The approach to the surgery involves creating anywhere from two to four incisions with portals leading to the damaged shoulder structure.

Through one portal, the arthroscope (an instrument with a camera on the end that is linked to a video screen so the surgeon can visualize the surgical site) is passed through to the site. The other portals are used for whatever surgical instruments are necessary to accomplish a specific procedure.

Let’s take a look at some types of arthroscopy shoulder surgery and the reasons they might be performed.

Shoulder Decompression Surgery

With shoulder impingement, shoulder decompression surgery (aka acromioplasty) is a common surgical solution. The idea is that bone spurs can form, causing impingement of the rotator cuff, and the bone spurs must be cut off and the ligaments or acromioclavicular (AC) joint cut away to release the pressure on the rotator cuff.

This surface idea, however, doesn’t take into account that those ligaments and the AC joint are major shoulder stabilizers, and typically the bone spurs form to protect the joint from instability.

When the structures that stabilize the shoulder are cut away during decompression surgery, understandably, this creates another problem: shoulder instability (1). So while the impingement may be addressed, over time, more trauma is experienced by the shoulder as a result of the decompression surgery. Learn more about this surgery in my short video below.

Labrum Repair or Biceps Tenodesis

Arthroscopy shoulder surgery is often recommended for shoulder labrum tears. The labrum is a protective lip positioned around the socket part of the shoulder joint.

Depending on the type of labrum tear, a surgeon may perform a labrum repair or a biceps tenodesis. In the former, the torn part of the labrum is removed or stitched back together. In the latter, the biceps tendon is detached from the shoulder socket and reattached at the humerus (the upper arm bone) (2).

The problem with these surgeries is that retearing of the labrum is unavoidable as the cause of the tear in the first place — typically hidden shoulder instability — is rarely discovered or addressed. If hidden shoulder instability isn’t addressed, more tears are inevitable. Like many orthopedic surgeries, this is another one I label a surgery that is damage to accomplish a goal.

For a visual of hidden shoulder instability and labrum tears, take a look at the GIF below:


In addition, labrum surgery is riddled with side effects, such as, for starters, infections, failure, chronic pain, loss of biceps strength, and in the case of the biceps tenodesis, even cosmetic deformity of the biceps (2,3,4).

Rotator Cuff Repair

The rotator cuff is the complex of muscles and tendons that support the shoulder. When a rotator cuff tear is found in MRI, a rotator cuff surgery involves stitching the tear back together, is often recommended. On an MRI report, these tears would be classified by degree: partial (involving only part of the tendon) or full-thickness (the tendon is torn completely through).

Further if the tear is full-thickness, terminology will include either retracted (snapped back, like a rubber band) or nonretracted (not snapped back). To learn more about your shoulder and reading your own MRI shoulder report, watch my video below:

Like any other arthroscopy shoulder surgery, the lack of effective outcomes of rotator cuff repair are also concerning. Below I have listed a handful:

Avoiding Rotator Cuff Surgery

These days, about 7 in 10 patients who are told they need arthroscopy shoulder surgery can avoid these procedures. How? Precise X-ray- or ultrasound-guided injections of your own platelets or stem cells can help with healing or reduce pain and increase function.

However, these are difficult procedures to perform correctly, so you need a physician super-specialist who is often not an orthopedic surgeon to perform these procedures. Specifically, they can not be performed at a high level by a nurse or physician assistant in a chiropractic office. To see what one of these procedures looks like, see my video below:

The upshot? Arthroscopy shoulder surgery can often be avoided, which is a good thing considering the side effects and the lack of evidence that we have that these invasive procedures are effective. So take some time to dive deep into your research on this procedure before pulling the trigger on surgery.
