Indications for Two-Incision (Outside-In) Anterior Cruciate Ligament Reconstruction

Anterior cruciate ligament (ACL) reconstruction is a commonly performed procedure. Drilling the femoral tunnel independent of the tibial tunnel has become popular as surgeons strive to create tunnels in the anatomic locations of the femoral and tibial attachments of the native ligament. The 2-incision technique effectively and reproducibly accomplishes this goal. The 2-incision technique for ACL reconstruction is a valuable tool in the skillset of the reconstructive knee surgeon. Indications for the 2-incision surgery are reviewed in detail. Furthermore, technical tips, complications, and outcomes are discussed.
