What Is the Best Peek Interference Screw in 2026?

Choosing the best Peek Interference Screw in 2026 is not simply a brand comparison. The right option depends on the graft, bone quality, tunnel dimensions, and the surgeon’s fixation plan. A screw that looks ideal in a catalog may not suit every reconstruction. Small details matter: thread geometry, diameter, length, insertion feel, and compatibility with the graft.

Dr. Freddie H. Fu, a prominent ACL surgeon and researcher, is known for advancing careful, anatomy-focused approaches to ligament reconstruction. A concise principle consistent with that clinical perspective is: “Match fixation to the graft, tunnel, and patient—not to the trend.” This is an editorial summary, not a verbatim quotation. It captures why a single screw cannot be called best for every case.

PEEK offers a radiolucent alternative to metal, which can help clinicians assess surrounding structures on imaging. But material alone does not guarantee stronger fixation or better outcomes. Design, surgical technique, and patient factors remain important. Look closely at published mechanical testing, clinical evidence, device specifications, and the manufacturer’s instructions. Ask what evidence supports the screw’s use in the specific procedure.

There are trade-offs. Some details remain uncertain, and product claims deserve scrutiny. This guide compares the features that matter in 2026, helping readers distinguish measurable performance from marketing language. The goal is informed discussion with a qualified orthopedic professional—not a universal recommendation.

What a PEEK Interference Screw Is and How It Works

What Is the Best PEEK Interference Screw in 2026?

A PEEK interference screw is used to secure a tendon graft during procedures such as ACL reconstruction. The surgeon places it between the graft and the wall of a drilled bone tunnel. As the screw advances, it compresses the graft against bone, helping hold it in place while healing occurs. That is the basic idea. Fit and placement matter.

PEEK, or polyether ether ketone, is a strong polymer that is generally radiolucent, so it creates less imaging obstruction than metal. A review by Kurtz and Devine in Biomaterials reported PEEK’s elastic modulus at about 3–4 GPa, compared with roughly 10–20 GPa for cortical bone. These are material measurements, not proof of better healing. Clinical results also depend on graft type, tunnel position, bone quality, and rehabilitation. The “best” screw is therefore not one-size-fits-all.

Tips: Check screw diameter and length against the tunnel and graft, and follow the surgeon’s technique and device instructions. Ask how the implant may appear on follow-up imaging. Small details count. Even good hardware cannot correct poor placement, and that is worth remembering.

Topic Evidence-Based Overview Why It Matters When Comparing Screws
What it is A PEEK interference screw is an implant made from implant-grade polyether ether ketone (PEEK). In ligament reconstruction, it is commonly used to secure a tendon graft within a drilled bone tunnel. It is a fixation device, not a replacement ligament. Its suitability depends on the graft, tunnel, procedure, and surgeon’s technique.
How fixation works The screw is inserted alongside the graft inside the bone tunnel. Its threads press the graft against the tunnel wall, producing mechanical compression and initial fixation. Secure fixation depends on factors including screw dimensions, graft size, bone quality, tunnel preparation, and correct placement.
Common clinical use Interference screws are used in selected ligament and tendon reconstruction procedures, including some anterior cruciate ligament (ACL) reconstructions. Fixation methods vary by procedure and graft type. A screw appropriate for one reconstruction may not be appropriate for another.
Material behavior PEEK is a strong, implant-grade thermoplastic. Its elastic modulus is commonly reported at roughly 3–4 GPa, although values vary by material formulation and testing method. Material properties are one part of performance; screw geometry, implantation technique, and the surrounding bone and graft also matter.
Imaging characteristics PEEK is radiolucent on standard X-rays and generally causes less imaging artifact than many metal implants. It is not necessarily invisible on every imaging study; design features and imaging technique can affect visibility. Consider how the implant will be assessed on postoperative imaging. Radiographic visibility may differ if a device incorporates a marker.
Resorption PEEK is a non-bioresorbable material. It is not designed to dissolve or be replaced by bone in the way that some bioabsorbable materials are. Material preference should reflect the clinical plan and the intended long-term presence of the implant.
Potential advantages PEEK offers a stable, nonmetallic option and is radiolucent. Its properties can be useful when clinicians want to avoid a conventional metal screw. These characteristics do not establish that PEEK is superior for every patient or reconstruction.
Potential limitations PEEK does not resorb, and radiolucency can make the screw itself less conspicuous on plain X-rays. As with other implants, complications may include fixation problems, infection, or the need for further treatment. Discuss imaging needs, material considerations, and procedure-specific risks with the treating surgeon.
What “best” means There is no universally best PEEK interference screw for 2026. The best choice is the device that is appropriate for the planned procedure, graft and tunnel dimensions, bone conditions, and the surgeon’s established technique. Compare intended use, available sizes, screw design, imaging features, and applicable clinical evidence rather than relying on a single overall ranking.
Key selection checks Confirm that the device is indicated for the intended procedure; that its dimensions match the planned graft and bone tunnel; and that its instructions for use and imaging characteristics are understood. Device selection and treatment decisions should be made by a qualified clinician using patient-specific information.

Key Materials, Designs, and Biomechanical Features

In 2026, “best” means a screw suited to the graft, bone tunnel, and surgical technique—not a universal winner. PEEK, or polyether ether ketone, is radiolucent, so it generally creates less imaging obstruction than metal. That can help clinicians assess the surrounding bone on follow-up images. The material is not absorbable, however, and imaging visibility does not guarantee fixation quality.

Design details matter. A tapered tip may ease entry, while thread depth and spacing influence how the screw engages bone and compresses the graft. The diameter and length should fit the tunnel without forcing insertion. Too much interference can damage a graft; too little may compromise initial stability. Small differences count. A clear drive recess and appropriate insertion instrument also help control placement, especially when access is limited.

Biomechanical performance depends on more than material. Graft type, bone quality, tunnel dimensions, and insertion angle all affect fixation, so laboratory strength alone cannot predict a clinical result. PEEK’s stiffness may provide stable support, but it does not remove the need for careful technique. No design is perfect. Selection should follow current clinical evidence and the treating surgeon’s assessment; the ideal balance between secure compression and graft protection can be difficult to judge.

Clinical Uses in Ligament and Tendon Reconstruction

Clinical Uses in Ligament and Tendon Reconstruction

There is no single best PEEK interference screw for every reconstruction. Surgeons use these screws to secure grafts inside bone tunnels, especially during anterior cruciate ligament reconstruction. The screw presses the graft against the tunnel wall. Picture a tendon graft seated in a drilled tunnel, with fixation helping hold it while healing progresses. Small details matter.

PEEK is radiolucent, so it generally creates less imaging obstruction than metal. This can help clinicians assess the surrounding bone on follow-up images, though visibility depends on the imaging method. Screw choice still depends on graft type, tunnel dimensions, bone quality, and surgical technique. A screw that fits one patient may not suit another. Fit matters.

In tendon reconstruction, interference screws may secure tendon grafts at selected bone attachment sites. They are one part of fixation, not a guarantee of healing or restored function. Evidence and device designs can vary, and the best option is not always obvious. Clinicians weigh mechanical demands, patient anatomy, and current product instructions. Even careful planning leaves room for uncertainty.

Criteria for Comparing PEEK Interference Screws

Criteria for Comparing PEEK Interference Screws

There is no single PEEK interference screw that suits every reconstruction. The right choice depends on the procedure, graft type, bone quality, and the surgeon’s technique. Compare screws designed for the intended tunnel and graft dimensions. A close match can support controlled placement; a poor fit may complicate fixation. Small details matter.

Review the screw’s diameter, length, thread profile, and tip design. These features affect how it enters the tunnel and engages the graft. Check that the driver seats securely, since slipping during insertion can disrupt control. PEEK is radiolucent, which can help keep the implant distinct from surrounding bone on images, but imaging needs vary. Also assess available clinical evidence, material documentation, sterilization information, and compatibility with the planned instruments. Evidence quality is uneven, so avoid relying on a single performance claim.

Tips: Confirm sizing against the operative plan, not appearance alone. Ask how the screw interacts with the specific graft and tunnel. A smooth insertion matters. So does reliable documentation. No checklist replaces clinical judgment, and some product details may be harder to compare than expected.

How to Choose the Best PEEK Interference Screw in 2026

How to Choose the Best PEEK Interference Screw in 2026 Choose by fixation needs, not by material name alone. Match screw diameter and length to the prepared tunnel and graft, then check the thread design, insertion profile, and instrument compatibility. Small details matter. A screw that advances smoothly can reduce handling frustration, but insertion feel alone does not prove secure fixation. ASTM F2026 sets material requirements for PEEK polymers used in surgical implants; it does not establish that every screw design performs equally. Ask for device-specific mechanical testing, sterilization information, and clinical evidence relevant to the intended procedure.

Look closely at the evidence behind the device. The American Academy of Orthopaedic Surgeons reports roughly 200,000 ACL injuries annually in the United States, but that broad figure does not tell you which screw is best for an individual reconstruction. Compare published outcomes, follow-up duration, complications, and the patient groups studied. Also consider imaging needs, because PEEK is radiolucent, while some designs include radiopaque markers. Fit matters. One limitation is easy to overlook: a polished specification sheet may not reflect the feel of insertion in a particular tunnel. Discuss graft type, bone quality, and fixation strategy with the surgical team before choosing.
