Abstract
The number of anterior cruciate ligament (ACL) ruptures treated arthroscopically has increased. In most cases, the rupture of the ligament occurs in the femoral attachment, leaving a robust stump attached to the tibia. ACL reconstruction with stump preservation might have some advantages: rapid reinnervation and revascularization of the graft. Most techniques have used an interference screw in tibial fixation, which could be more difficult to achieve the graft diameter within 8 to 10 mm in most situations. Therefore, we describe a technique for modified “all-inside” ACL reconstruction with remnant preservation using an appendiceal tibial tunnel to optimize the graft size. After tunnel drilling in anatomic positions, the ACL stump is bored centrally up to the diameter of the graft to be passed. After passing the graft from the tibial tunnel to the remnant to the femoral tunnel, adjustable loops are used to fix the femoral side and the tibial side by an appendiceal tibial tunnel.
