Why do ACL take so long to heal?

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. Oftentimes, ACL tears require a surgical graft.

Why does ACL recovery take so long?

Why is the ACL recovery period so long? The reason for this is due to the biological changes which the graft will need to undergo in order to re-incorporate into the body. Once a graft is disconnected from the body, even for a short time, the cells within it undergo necrosis (i.e. die).

Why is the ACL so hard to heal?

Why are ACL tears so serious?

Most importantly, the ACL aids in the stability of the knee joint, preventing it from shifting during quick side-to-side motion such as shuffling, sidestepping, or cutting. Without an ACL, the knee is very unstable (and weak) during lateral movement.

Can an ACL heal naturally?

Complete ACL tears cannot heal on their own, and therefore, almost always require surgical intervention. The ligament, given its location in the knee, cannot spontaneously heal because it has poor blood supply to it.

Will my knee ever be normal after ACL surgery?

Patients walk unassisted within 2-4 weeks, but for short periods. After 10-12 weeks, expect brisk walking, light jogging, and even plyometric exercise. Full recovery on ACL reconstruction is 6-12 months, or more with physical therapy.

What not to do after ACL surgery?

Don't work your quadriceps early on because this can stretch the ACL graft. Stationery bike riding or lightweight leg presses are recommended during the first three months after surgery. These exercises strengthen the quadriceps while using the hamstrings to protect the ACL graft. Don't swim or run for five months.

What cardio is best for ACL injury?
