Thousands Who Undergo a Common Knee Surgery May Be Making Their Problems Worse

Thousands Who Undergo a Common Knee Surgery May Be Making Their Problems Worse

Why this article matters

For many years, arthroscopic surgery to “clean up” degenerative meniscal tears was one of the most commonly performed orthopedic procedures. Over the past decade, however, multiple randomized trials have challenged whether the operation provides meaningful long-term benefit for most patients with age-related degenerative tears.

This article highlights the growing body of evidence suggesting that many patients may not benefit from surgery—and in some cases may experience worse long-term outcomes.

Key takeaways

* Degenerative meniscal tears are extremely common, especially after age 40.
* Many tears are part of the natural aging process rather than the primary cause of pain.
* High-quality clinical trials have repeatedly shown that arthroscopic partial meniscectomy often performs no better than structured rehabilitation for degenerative tears.
* Careful patient selection remains essential, as not all meniscal tears are the same.

Dr. B’s  Commentary

These findings should not be interpreted as “knee arthroscopy never works.”

Instead, they reinforce something pain and orthopedic specialists have learned over the last decade:

The diagnosis matters more than the MRI.

Many patients have degenerative meniscal tears that are incidental findings rather than the true source of their symptoms. Removing part of the meniscus cannot reliably improve pain if another structure—such as osteoarthritis, synovitis, subchondral bone, ligament injury, or another tissue—is actually responsible.

Likewise, not every meniscal tear should be managed without surgery. Acute traumatic tears, displaced bucket-handle tears, true mechanical locking, and certain repairable tears remain appropriate surgical indications.

What this means for patients

Patients considering knee arthroscopy should first answer a more important question:

What is actually causing my knee pain?

A thoughtful evaluation—including history, physical examination, imaging, and when appropriate, diagnostic ultrasound—often provides greater value than simply identifying a meniscal tear on MRI.

Treatment should be directed at the true source of symptoms rather than the most obvious imaging finding.

Bottom line

This article reflects an important shift in orthopedic medicine: more surgery is not always better surgery.

The goal should never be to operate on an MRI finding. It should be to identify the true source of a patient’s symptoms and choose the least invasive treatment most likely to improve pain and function.
