PEEK Suture Anchor: Material, Design, Sizes and Applications

A PEEK Suture Anchor is an orthopedic fixation device designed to help secure soft tissue to bone. It is commonly considered for procedures involving the repair or fixation of tendons and ligaments. Compared with conventional metal anchor designs, PEEK provides a non-metallic material option for orthopedic implant applications.

For medical device distributors, orthopedic implant companies, and OEM customers, selecting a PEEK Suture Anchor requires consideration of more than the anchor diameter. Material, anchor design, length, suture configuration, insertion method, and intended application should all be evaluated when selecting an appropriate product.

What Is a PEEK Suture Anchor?

A PEEK Suture Anchor consists of an anchor body and suture used for soft-tissue fixation to bone. Depending on the product design, the anchor can be inserted into a prepared bone site, while the attached suture is used to secure the targeted soft tissue.

PEEK, or polyether ether ketone, is an engineering polymer that has been used in orthopedic and other implantable medical applications. One characteristic of PEEK is its radiolucency, which means that it does not produce the same type of radiographic appearance as a metallic implant. This can be useful when postoperative imaging is required because PEEK may reduce metal-related imaging artifacts compared with metallic implants.

Why Choose PEEK for a Suture Anchor?

Material selection is an important consideration when developing a PEEK Suture Anchor. PEEK combines mechanical properties suitable for selected orthopedic applications with a non-metallic material profile.

Radiolucent material: PEEK is radiolucent, allowing X-ray imaging to visualize the surrounding bone and tissue without the same degree of radiographic obstruction associated with many metal implants.

Non-metallic composition: A PEEK-based anchor provides an alternative to metallic anchor materials for applications where a polymer implant is preferred.

Material stability: PEEK has good chemical and dimensional stability, which are relevant characteristics for medical device manufacturing and implant applications.

Established orthopedic application: PEEK has been studied and used in orthopedic implant applications, including suture anchor systems. However, the performance of an individual implant depends on its specific design, manufacturing process, and intended use.

Knotless PEEK Suture Anchor Design

The Well Trust PEEK Suture Anchor shown in the product range uses a knotless anchor configuration. The product information features a classic inverted-tooth structure and different anchor models for various size requirements.

The product range includes several diameter and length combinations. Available specifications shown in the product information include 2.5 × 8.5 mm, 2.9 × 15.5 mm, 3.5 × 20 mm, 3.5 × 16 mm, 4.5 × 24 mm, 4.75 × 19 mm, and 5.5 × 19 mm configurations.

Different sizes allow customers to select a PEEK Suture Anchor according to the intended surgical application, anatomical location, and requirements of the corresponding instrumentation system.

PEEK Suture Anchor for Soft Tissue Fixation

Suture anchors are used in orthopedic procedures where soft tissue needs to be attached or reattached to bone. Depending on the specific product and its approved indications, applications may include tendon and ligament repair in areas such as the shoulder, ankle, foot, elbow, wrist, or other joints.

The product information supplied by Well Trust describes the anchor as suitable for double-row, knot-free repair of injuries near the extremities of ligaments or tendons. The appropriate application should always be determined according to the specific product documentation, surgical technique, and regulatory requirements of the destination market.

How to Select a PEEK Suture Anchor

When sourcing a PEEK Suture Anchor, buyers should consider several technical factors:

Anchor diameter and length: Select the appropriate dimensions according to the intended procedure and bone anatomy.

Anchor design: Confirm whether a knotless configuration and the specified tooth or thread structure are appropriate for the intended application.

Suture configuration: Check the required suture type, number of sutures, and loading configuration according to the surgical system.

Instrumentation compatibility: The anchor should be matched with the appropriate inserter, driver, drill, or other instruments where applicable.

Regulatory requirements: Product indications, sterilization, packaging, and regulatory status should be verified according to the specific product and destination market.
