Why can’t I kneel after ACL surgery?

Kneeling puts your weight on a small patch at the front of the knee, where many grafts and incisions sit.

How common is an ACL graft re-tear?

Across 14 studies of younger athletes, about 7% of ACL grafts tore again. In one review of people over 40, it was under 3%.

Is it normal to be afraid of reinjury after being cleared?

Yes. After ACL reconstruction, many people return to some sport but not their old level, and lower fear of reinjury was linked to getting back to it.
