After anterior cruciate ligament (ACL) reconstruction, the tibial tunnel becomes widened over time. A revision surgery of the ACL reconstruction is required to fill the widened tunnels. Bone-patellar tendon-bone grafts often are used to fill enlarged bone tunnels. However, due to the variation in tendon length, it is often difficult to adjust the position of the bone fragment to the enlarged part of the bone tunnel. This study describes an arthroscopic ACL reconstruction technique using the semitendinosus tendon as well as a bone fragment which is placed in the enlarged tibial tunnel. The tendon and cortical bone were collected together at the tendon attachment using a flat chisel. The bone fragment was inserted through the tendon in a controlled manner and ultimately placed at the posterior wall of the tibial foramen. This technique was determined to be less invasive than using bone-patellar tendon-bone in a 2-stage revision ACL reconstruction. In addition, this technique can be easily performed by any surgeon who is accustomed to conventional ACL reconstruction using the semitendinosus tendon and does not require any special equipment. Our findings suggest that this technique may be useful for revision ACL reconstruction.
