Magnetic resonance imaging (MRI) revealed a displaced femoral avulsion fracture of the ACL (Figure 1).
Arthroscopy, notch; ACL tear.

The ACL was proved to be lax with the expected femoral avulsion (Figures 2 and 3).

USA). Using a 5.5 mm offset drilling guide, a beath pin was inserted at the anatomic femoral insertion site of the ACL via the anteromedial portal (Figure 4).

Using an arthroscopic lasso, 2 strands of No. 2 DynacordTM (DePuy Mitek, Raynham, MA, USA) non-absorbable sutures were shuttled through the proximal part of the ACL stump (Figure 5).
Arthroscopy, notch; anatomically reducted ACL.
