Damaged fibrous rings take a long time to recover.
However, even after a long time, they do not recover completely.

The image below is an MRI taken after a contrast agent injection following a disc rupture.
When a contrast agent is injected for imaging, you can see the disc annulus being filled in, as indicated by the arrow below.
However, this MRI can be seen as an image showing the healing process of a disc rupture, giving us an idea of the extent of the annulus tear. Doctors say that even after five years, the annulus cannot fully recover from damage caused by a rupture. This is likely why patients who have suffered annulus injuries can easily experience another disc rupture, even if they seem to have healed. The annulus doesn’t regenerate with its original fibrous material; instead, it fills in with more of a gelatinous substance. It’s truly unfortunate
