One-stage revision anterior cruciate ligament reconstruction with impacted bone graft after failed primary reconstruction.

Revision anterior cruciate ligament reconstruction can be performed in a 1- or 2-stage procedure. Restoration of bone stock using bone grafting is often required for good results. The authors performed 1-stage revision surgery with a more lateral and oblique femoral tunnel and an impacted bone graft to avoid the bone defect caused by the previous screw removal from a malpositioned tunnel. No evidence existed of revision surgery failure or viral transmission in any of 17 cases at 2-year follow-up. The authors' technique is also useful for a slightly misplaced femoral tunnel.
