Yes, most meniscus tears will hurt, but the pain from many meniscus tears might go away completely with physical therapy.   The meniscus is a cartilage disc in the knee.  The meniscus does not regenerate or heal like our skin after it is cut.  Therefore, over time the meniscus can become weakened from repetitive stress and eventually tear.  We can tear our meniscus with trauma or without trauma.  The meniscus has no nerves in it… so why does a meniscus tear hurt?

Meniscus tears are a very common cause of knee pain.  But not everyone with a meniscus tear will have severe pain.  Some of you may have no pain at all if you give your knee a few weeks to rest. If your pain persists despite a few weeks of rest or PT then we may consider repairing your tear.  Many more tears are repairable than we previously thought.

Why do meniscus tears hurt?

Knee pain is very common.  It can occur out of the blue, after a long tennis match, a long walk, or following a sports injury or an accident. One of the more common reasons for knee pain is a meniscus tear.   Many more questions arise.

  • What motion makes a meniscus tear hurt?
  • Can your symptoms or complaints determine what treatment might be necessary?

Do all meniscus tears hurt?

Yes, at some point in time most all meniscus tears will hurt.  But that doesn’t mean they will hurt for a long time.   In many cases the pain from a meniscus tear will either improve significantly or go away without surgery.   In cases where there was an injury which preceded the meniscus tear, you may have knee pain and swelling with virtually  all activities.  These “acute” meniscus tears usually occur in younger active individuals.  The tear may cause “mechanical” pain such as popping, locking or even cause your knee to catch or feel unstable.   Most people with acute, traumatic  meniscus tears should consider surgery to repair the tear.

Acute traumatic meniscus tears are less common than degenerative tears.  With a degenerative tear, rushing in for an MRI and rushing to schedule surgery isn’t usually necessary since your knee pain has a good chance of settling down within 4-6 weeks.  Tears that continue to hurt with pivoting or twisting and cause the knee to feel unstable might require surgery for a meniscus repair.

Most meniscus tears are attritional, or “degenerative” in nature.  When you read about scientific studies showing that knee surgery might not be successful they are usually talking about these “degenerative” meniscus tears.  That simply means that your cartilage wore out.  It wore out from all your activities throughout your life.   In patients who have a degenerative tear, or a meniscus that simply wore out, many patients will only have pain for a few weeks.  Most of you with a degenerative meniscus tear will not have any of the mechanical symptoms I mentioned above.  Very few patients with degenerative meniscus tears will ever need surgery.  Many patients with degenerative tears note that their pain improves when their wear a compression sleeve on their knee.

In general, there are many types of meniscus tears, and the type of tear you have will determine the type of pain you will have, and how long you will have it.

The meniscus itself does not have any nerves in it. So how does a meniscus tear  cause knee pain?  Meniscus tears hurt because they upset the lining or the synovium of the knee.   The synovium has  a lot of nerves in it and this synovium will cause significant pain, and swelling when it is irritated.

Your knee can feel better without surgery. All meniscus tears do not need to be fixed.  In patients with degenerative or attritional meniscus tears, again, a situation where your meniscus tissue simply wore out, you may not have severe pain, or swelling.  You may notice knee pain with certain maneuvers or may feel like the knee is a bit swollen, but you will be far more comfortable than someone with knee pain from an acute, traumatic meniscus tear following an injury. Most patients with a meniscus tear often experience relief within a few weeks… and usually respond well to physical therapy,  a compression sleeve and natural, strong anti-inflammatories such as Tart Cherry Juice

Knee Pain — when do meniscus tears hurt?

In many situations your knee pain will improve dramatically over the course of a  few days to a few weeks (one reason not to rush into an MRI machine).   The typical patient with a meniscus tear doesn’t have much in the way of pain with walking straight ahead or in one direction.  Sometimes they do.  It depends on the size of the tear but you will usually tolerate walking in a single direction very well.  Patients with certain meniscal tears will complain of pain going downstairs.  They’ll have knee pain getting up from a seated position.  They’ll have knee pain with turning, pivoting and twisting— and they usually have severe knee pain with kneeling or squatting.  If the meniscus tear is large  you might notice that the knee is buckling, giving way or feels unstable. If you have instability, or if your knee is locked and will not move you may have a bucket handle or flap tear that will likely require surgery.  That is a situation where you should see us sooner rather than later.

If you have a knee that feels loose, or unstable — or the knee is catching, please call us.  You need to be seen.  If you have a vague ache with certain maneuvers, rests, stretch, try a compression sleeve and your pain should subside within a few weeks.
