Interference screws

An interference screw is a direct tendon-to-bone interference fixation device. It is a compression fixation device that relies on the screw threads to engage and compress the graft for fixation. It is most commonly used in anterior cruciate ligament reconstruction.

One notable specific type of interference screw is the Kurosaka screw, which is designed to anchor an anterior cruciate ligament (ACL) graft into the lateral femoral condyle and proximal medial tibial metaphysis.

Radiographic features

Plain radiography

They can either be metallic (radiodense) or bioabsorbable (radiolucent). They are usually seen on either end of the tunnel or in the case of bioabsorbable screws only the tunnel is seen.
