ACL Surgery May Not Be Needed in Half of Knee Injury Cases

half of ACL knee injuries may not need surgery Angel Nieto/PhotoSpin

A friend of mine injured her knee when she fell on a New York City street. X-rays taken at the emergency room did not show any fractures but her knee just didn’t feel right and continued to hurt.

She went back to the ER a couple of days later and an MRI showed she had a total tear of her ACL (anterior cruciate ligament).

The orthopedic resident who looked at the MRI results told her she probably didn’t need surgery with this type of injury.

I did some research and found that there were some circumstances that an ACL tear was not surgically repaired. It seemed to mostly be a practice in those who were not very active or had good stability in their knees despite a tear.

I urged her to question the orthopedic doctor she went to see for follow up to explain to her how the decision is made to do a surgical repair or not.

She said her doctor told her that while ACL tears are frequently repaired here in the United States, that in some Scandinavian countries they weren’t in such a hurry to perform surgery.

Many people did well with just physical therapy and may not need surgery.

He explained that the ACL is an important stabilizing ligament for athletes who do twisting motions such a basketball players but for many of us, stability and support from the other ligaments surrounding the knee would be enough.

What she was told surprised me, so I had to do more research to find out why.

Science Daily reported that a Swedish study published in 2010, with a followup study in 2012, supported the practice of trying rehab alone instead of surgery, and rehab for patients with ACL tears.

The study published in 2010 actually involved patients recruited from February 2002 through June 2006, and the two-year follow-up was concluded in June 2008. The research group was called the KANON study (knee ACL non-operative versus operative) from Lund University in Sweden.

A total of 121 patients between the age of 18 and 35 were randomly divided into two groups. One group had rehabilitation plus early ACL reconstruction and the other had rehabilitation alone with the possibility of surgery later if needed.

A very helpful post for those athletes who commonly have this problem. I have a friend who got a knee injury before too, and we were so thankful that surgery was not an issue about it. But we never learned about this until we came across with this post. Hope more people can read this one.
