Anterior Cruciate Ligament (ACL) tear -What is ACL?-

I would like to write about ACL tear, since a friend of mine requested.

Many physiotherapists study about ACL tears, but I don’t like the case of ACL tear.

Because it is impossible to restore completely.

I think there are 2 ways of treatment.
・rebuilding the ligament by surgery.
・strengthening muscles of Quadriceps, and teaching how to move without a stress onto the ligament.

Once you rebuild the ligament by surgery, you can play hard sports again.
Though it is possible to play some sports without surgery, you have to be very careful not to have injured again.

Well, now I write about ACL…

What is ACL?
ACL is short for Anterior Cruiate Ligament.

the figure in rigiht, I made ACL on the bone model. (red)→

from anterior of Tibia, which is the bone below the knee to posterior of Femur, which is the bone in thigh.
This ligament control the Tibia not to move forward.

← And I made Posterior Cruciate Ligament(PCL) as well. (blue)

These ligament were named “cruciate”, because they are crossing as cruciate in the knee joint.
These 2 cruciate ligaments are very important to keep knee stable.

Then, how does ACL tear occur?
I will explain in the next blog.
