Choosing the Right Suture Anchor: PEEK vs. Biocomposite

When performing rotator cuff repairs or labral reconstructions, one of the most critical decisions is the selection of implant material. Historically, metal anchors were the standard. However, the orthopedic community has shifted towards PEEK (Polyetheretherketone) and biocomposite materials. AxenMedical stands at the forefront of this materials science revolution.

PEEK: Ultimate Strength and Radiolucency

PEEK is a high-performance thermoplastic known for its excellent mechanical properties. It matches the modulus of cortical bone, is fully radiolucent (meaning it doesn't block X-rays or MRI scans), and is highly biocompatible. For high-tension fixation, PEEK anchors provide the security surgeons depend on.

Biocomposites: Promoting Natural Healing

On the other hand, biocomposite materials (such as blends of PLDLA and beta-TCP) are designed to be absorbed by the body over time. As the material slowly degrades, it is replaced by native bone. This biological healing process is ideal for joint preservation, leaving no permanent hardware behind once the tendon has successfully healed to the bone.

At AxenMedical, we produce both PEEK and biocomposite suture anchors to give surgical teams the versatility they need to optimize patient-specific outcomes.
