Abstract: | Few cases have been reported in which the femoral interference screw has migrated into the posterior compartment after an
ACL reconstruction. It usually requires removal, because it leads usually to mechanical symptom. However, the arthroscopic
removal of a screw is a technically demanding procedure, especially in the case of the femoral interference screw that has
migrated into the femoral notch (posterior compartment), an intact integrated ACL graft or one that is encapsulated around
the screw. We present a case in which a displaced femoral interference screw migrated within the posterior compartment 11 years
postoperatively, after the graft had been incorporated at the femoral site. Although it is often technically challenging,
through the use of a posterior trans-septal portal, we can successfully remove a displaced femoral interference screw even
in the most difficult locations in the posterior compartment. |
