Is it ok to run with a torn ACL?


Answer by Dominique:


Hi there,
Thanks for your question about running with a torn ACL. It does not sound like a good idea, does it?

I'll try to explain why it is not a good idea:

Your anterior cruciate ligament links the femur (the big bone in your thighs) to the shin bone.




On top of the shin bone is cartilage. When the ACL is torn your knee becomes unstable and wobbly. When you run your thigh bone can start rubbing on the shin bone and that can cause significant cartilage damage.

Now, when it is just a little tear then you have got a good chance that ice and rest and rehab that focuses on building the muscles around the knee will get you back to running again within a number of months.

When it is a bigger tear then chances are that you may need surgery to get the ACL fixed.

I would highly recommend working with a doctor to find out the best way forward with your ACL. Until then, definitely lay off running.

Best of luck.
