PEEK CF Interference Screws
V-LoXTM and V-LoX3 Titanium

PEEK CF Interference Screws

The polymer used in our PEEK CF Interference Screws is twice as strong as the Natural PEEK used by other manufacturers and has mechanical characteristics much closer to cortical bone than either PLLA or Titanium.


  • Stronger than PLLA and Bio-composites

  • Less likely to elicit foreign body reaction

  • Radiolucent with less imaging artifact

  • Use in both intra- & extra-capsular ligament reconstruction

What is PEEK CF?

Parcus Medical is the first to make implantable products using PEEK CF for the Sports Medicine industry. PEEK CF is made of PEEK-Optima™ (by Invibio™) combined with 30% carbon fiber fill. The compound is comprised of short carbon fibers that are dispersed within a PEEK-Optima™ polymer matrix. The polymer in PEEK CF encapsulates the carbon fibers.

The resulting material has enhanced physical strength - nearly twice as much as natural PEEK - and has mechanical characteristics much closer to cortical bone than natural PEEK, PLLA or Titanium. The added mechanical strength in PEEK CF plays a key role in addressing the challenges of insertion torque in screw-in devices such as suture anchors and interference screws.

The PEEK CF Difference

  • Strong and biocompatible

  • Radiolucent, less imaging artifact, MR safe

  • Twice as strong as the PEEK material used in other suture anchors

  • Mechanical properties closer to cortical bone than titanium or biocomposites
