Anatomic double-bundle anterior cruciate ligament reconstruction revision surgery.
With the increasing number of double-bundle anterior cruciate ligament (ACL) reconstructions being performed, revision cases are expected. This report describes the first 3 cases of revision double-bundle ACL surgeries performed at our institution. In 3 athletes in whom the ACL was previously reconstructed with an anatomic double-bundle technique, new traumatic events occurred and an ACL retear was diagnosed. In cases 1 and 2 the anteromedial (AM) bundle was completely torn and the posterolateral (PL) bundle was stretched and nonfunctional. In case 1 both bundles were reconstructed via the previous tunnels, and the AM and PL grafts were tensioned at 60 degrees of flexion and full extension, respectively. In case 2 the PL femoral tunnel was posterosuperior to the PL anatomic position. Therefore we drilled a third femoral tunnel and used the previous PL tunnel as our new AM tunnel. In case 3 the rupture pattern presented an intact and functional PL bundle and a midsubstance AM tear. We decided to revise only the AM bundle using the previous AM tunnels, which were anatomically positioned. This report shows that revision of anatomic double-bundle ACL reconstruction is reasonable to accomplish and that the principles of anatomy are essential as a guide to approaching each case.
