Why is an ACL injury so bad?
Like all ligaments, the ACL takes a very long time to heal.
The reason is because ligaments are poorly vascularized.
In other words, there aren’t many blood vessels to provide nutrients for the ligaments, and without nutrients, tissue repair is not possible..
Can straighten but not bend knee?
You may momentarily feel like you are unable to fully bend or straighten out your knee. This happens because a torn part of the meniscus flaps into the joint and gets caught within, preventing the knee from functioning normally. If the knee becomes permanently locked up, urgent surgery is required.
What’s worse MCL or ACL tear?
With an MCL tear, the recovery process may take up to eight weeks or more with rehabilitation. On the other hand, an ACL tear will most likely require surgery and at least six months or more of rehabilitation. A torn ACL or MCL is a serious injury that should be assessed and treated by an orthopedic surgeon.

What happens if a torn ACL goes untreated?
