Predicting and controlling solute release from a bioactive degradable interference screw for ACL reconstruction

摘要

The progressive replacement of metallic implants by polymeric implants, although advantageous in many ways, is posing new medical challenges. In the case of anterior cruciate ligament (ACL) reconstruction, polymeric interference screws take a really long time to fully degrade, occasionally up to 3 years. Furthermore, they leave voids at the site of insertion after they degrade between the ligament and the surrounding bone tissue [2].
