Meniscus tears are very common.  Since most people over 55 will have one and nearly everyone over 70 will have one it is normal to wonder if a meniscus tear can heal without surgery.

Yes, some meniscus tears can heal on their own.  Even if a meniscus tear doesn’t heal, many older degenerative tears will stop hurting if treated without surgery.  Perhaps more important is that many meniscus tears do not surgery.  What? Really?  Yes… most meniscus tears are degenerative and will not require surgery.  Some tears, particularly those in athletes or meniscus tears that occurred due to trauma will require surgery.  Thankfully most acute meniscus tears can be sutured or repaired.  Healing after a meniscus repair is becoming more successful with better techniques.

The meniscus is a “C”-shaped cartilage disk in the knee.  There are two menisci within each of our knees.  A normal meniscus serves a very important role as a shock absorber and as a stabilizer.  When a meniscus tears, it can lead to pain, instability, locking  and it can lead to osteoarthritis over the long term.  Staying active and staying in the game is important … so getting a meniscus tear to heal may be very important to you.

types of meniscus tears

 

Whether or not a meniscus tear can be fixed, and whether or not a meniscus tear might heal depends on the type of tear and the cause of the tear.

A a surgeon, I look at the cause of your meniscus tear and the type of meniscus tear you have.  Once I know what type of tear you have I can determine if your meniscus tear will heal on it own, or if it might require surgery to help it heal.

There are different types of meniscus tears. Eg.

There are different causes of meniscus tears.

Acute injuries can cause meniscus tears (longitudinal, peripheral, bucket-handle and radial tears) …

but most meniscal tears (complex, degenerative, and horizontal cleavage)  are caused by degeneration, and wear and tear.

Meniscus Healing

The meniscus serves a very important function.  Therefore, now more than ever, we try to focus on meniscus preservation or healing.  That means our goal is to try and fix or suture your tear so that it will heal.  Be careful, occasionally a surgeon might tell you they will “fix” your meniscus … but they are actually intent on cutting the torn portion out.  Be sure to clarify this with them before considering which surgeon should repair your meniscus tear.  I should also state that we are not talking about treating highly degenerative or worn out tears in people in their 7th and 8th decades.  Those tears are not repairable and most usually do not need to be operated on. Most people with degenerative tears will do very well with a compression sleeve and physical therapy and moderate exercise.

Can my meniscus tear be repaired?

Over the past few years a lot of research has focused on the healing potential of certain tears we once thought would not heal. We know that the peripheral 1/3 of a meniscus has a blood supply adequate enough to bring healing nutrients to the area of the tear.  Therefore, it was always assumed that only tears within the outer 1/3 of a meniscus would heal once they were sutured or stitched back together.  Recent research has shown that tears with little blood supply are still capable of healing after they have been sutured together.  Horizontal cleavage tears were once considered a degenerative tear not capable of healing.  This paper, and others shows that horizontal cleavage tears can be repaired, with a reasonable chance of success.  Radial tears of the meniscus were also considered not repairable, and most surgeons would simply cut out the torn portion, leaving you at risk for developing osteoarthritis.  This paper shows that we are now capable of fixing radial tears of the meniscus, again with a reasonable chance of healing.

Compression sleeves will not cause a meniscus to heal, but many patients note that their knees feel better when wearing them.

Furthermore,  newer devices are now available to help us suture complex tears together so that they can possibly heal.

Can Meniscus Tears Heal Without Surgery

When you first started reading this you were likely reading to see if your tear could heal on its own — without the need for surgery.  In a very small group of people that can happen.  Meniscus tears that heal themselves tend to be traumatic tears which occur at the same time you tear your Anterior Cruciate Ligament, or ACL.  Otherwise most tears will not heal unless they are sutured back together.

Bottom Line:  The meniscus serves a very important function within our knee.  If the meniscus is torn, it can not serve to protect your knee from developing osteoarthritis.  Many tears are now repairable with modern techniques.  If these repairs are successful at restoring the integrity of the meniscus, then you may not go on to suffer the consequences of an arthritic knee.

Repairs are generally reserved for acute, traumatic tears in children and young adults.  Surgery for degenerative meniscus tears in adult knees with osteoarthritis is rarely required.  Although your degenerative tear will not heal spontaneously, physical therapy and other non-surgical measures are usually effective at minimizing pain and maximizing function as effectively as surgery.
