Description

ACL Screws PEEK (Polyether Ether Ketone):

PEEK interference screws are commonly used in ACL (Anterior Cruciate Ligament) reconstruction surgeries. They are made from a high-performance polymer called Polyether Ether Ketone (PEEK), which is biocompatible and radiolucent.

Key Features:

Material: PEEK – non-metallic, biocompatible, strong, and lightweight.

Radiolucent: Does not cause imaging artifacts on X-ray, CT, or MRI.

Bioinert: Does not degrade inside the body, maintains long-term stability.

Thread Design: Sharp, deep threads provide strong fixation of grafts in bone tunnels.

Sizes: Available in different diameters (usually 6 mm – 12 mm) and lengths (20 mm – 35 mm) to match graft and tunnel size.

Head Design: Usually has a hex or Torx drive for easy insertion with a screwdriver.

Application: Used to secure the soft tissue graft inside the bone tunnel during ACL or PCL reconstruction.

Advantages Over Titanium Screws:

No metal interference in imaging (MRI/CT).

Elastic modulus closer to bone → reduces stress shielding.

No risk of metal allergies or corrosion.

Lightweight and easy handling.
