PEEK Interference Screw

What Is a PEEK Interference Screw

A PEEK interference screw is an orthopedic fixation implant designed to secure soft tissue or tendon grafts within a pre-drilled bone tunnel during arthroscopic ligament reconstruction procedures.

It achieves fixation through controlled radial compression between the graft and surrounding cancellous bone.

Role in Modern Arthroscopic Fixation Systems

In contemporary sports medicine, PEEK interference screws are considered a standard fixation option for minimally invasive ligament reconstruction due to their predictable mechanical behavior and imaging compatibility.

Primary Ligament Reconstruction Indications

• Anterior Cruciate Ligament (ACL) reconstruction

• Posterior Cruciate Ligament (PCL) reconstruction

Soft Tissue and Tendon Fixation Applications

• Hamstring tendon graft fixation

• Patellar tendon graft fixation

• General soft tissue graft anchoring

Use in Minimally Invasive Arthroscopic Surgery

PEEK interference screws are specifically designed for arthroscopic insertion, enabling controlled placement through minimally invasive portals while maintaining stable graft compression.

Fixation Behavior Under Cyclic Knee Loading

The screw provides resistance to graft slippage under physiological cyclic loading, supporting early rehabilitation protocols.

Radiolucency and Imaging Compatibility

PEEK is radiolucent, allowing clear post-operative MRI and CT imaging without artifact interference.

Biomechanical and Biological Performance

• Elastic modulus closer to cortical bone

• High fatigue resistance

• Excellent long-term biocompatibility

Optimized Thread Geometry

The thread profile is engineered to enhance engagement with cancellous bone while minimizing graft damage during insertion.

Controlled Compression and Stability

The interference mechanism generates uniform compression along the graft-bone interface, improving fixation reliability.
