PEEK Interference Screw

What is the PEEK Interference screw?

PEEK Interference screws are used for fixation of anterior and posterior tendon repairs, are made of PEEK (Poly Ether-Ether Kethon). These screws are also used on BTB and soft tissue fixations. Fully threaded and blut screws protect the graft from laceration on insertion.

Interference screw is a popular fixation device used to rigidly fix bone-patellar tendon-bone (B-PT-B) graft both in femoral and tibial tunnels in anterior cruciate ligament (ACL) reconstruction. Parallel placement of screw is difficult in transtibially drilled femoral tunnel but always desired as it affects pullout strength of the graft. Commonly, interference screw into the femoral tunnel is inserted through the anteromedial (AM) or accessory AM portal. These portals are not-in-line with the transtibially drilled femoral tunnel. Furthermore, these portals increase the divergence of the interference screw in the femoral tunnel. We hypothesized that interference screw placement through patellar tendon (PT) portal (through donor defect) in transtibially drilled femoral tunnel can be less divergent.

What are interference screws made of?

CZMEDITECH Interference Screws are of the highest quality standard. A complete family of interference screws includes Bio-Interference Screws (primarily amorphous PLLA Full Thread),  PEEK Interference Screws,  Metal Interference Screws (made from titanium for femoral and tibial fixation of a soft tissue or bone-tendon grafts in cruciate ligament reconstruction procedures), and Sheath Cannulated Screws (translucent sheath).
