Use of the "blue dot" in femoral bone plug of bone-patellar tendon-bone graft in anterior cruciate ligament reconstruction.
The advancement of the femoral bone plug, with proper orientation through the femoral tunnel is often one of the most difficult maneuvers in the reconstruction of the anterior cruciate ligament using a bone-patellar tendon-bone graft. The authors describe a modification to the procedure featuring the use of methylene blue marker (to make a ¿blue dot¿) to highlight the site of drill holes as well as the anterior bone-tendon junction. The ¿blue dot¿ aids the localization of the drill hole with a probe and thus the advancement of the femoral plug through the femoral tunnel.
