Completely agree with your post and Dr.Chhabra comments.
I think the explanation lies in anatomy. The ACL shares fibers with the anterior horn of the lateral meniscus.
Oblique coronal section of the ACL and cadaveric correlation.

Somewhat unusual longitudinal tear of the anterior horn of the lateral meniscus associated with a high grade partial ACL. 38 y/oF who slipped and fell.
I’ve seen many cases of mucoid degeneration of the ACL where the mucoid material extends into the ant horn of the lateral meniscus through the shared root attachment. (a few times arthroscopically proven)
I have never seen an ACL tear with this association (don’t remember is more like it) and think it must be a twisting shear type injury? Is mucoid degeneration sometimes a chronic partial tear? I’m sure folks here know. Most of the literature concentrates on the posterior horn injuries with an ACL tear.
If interesting to you, feel free to reply and discuss. I can certainly learn.
