Arthrex AR-8991 FiberTak DX Knotless Suture Anchor - 1.6mm All-Suture Anchor with FiberViwer Tail

Arthrex DX FiberTak® | Knotless All-Suture Anchor | 1.6 mm | AR-8991

The Arthrex AR-8991 (DX FiberTak®) is a state-of-the-art fixation solution engineered for 2026 standards in extremity surgery. This ultra-low-profile, all-suture anchor is specifically designed to manage the unique challenges of small joint anatomy, where bone real estate is limited and hardware prominence is a major concern.

By utilizing a 1.6 mm drill path, the FiberTak DX preserves significantly more bone stock than traditional hard-body anchors. The knotless mechanism allows the surgeon to incrementally tension the repair after anchor deployment, providing unparalleled control over ligamentous laxity without the bulky "knot stacks" that can cause soft-tissue irritation in thin-skinned areas like the hand or ankle.

Key Performance Features

• Ultra-Low Profile (1.6 mm): Requires one of the smallest footprints in the industry, making it ideal for the limited cortical space found in phalanges, metacarpals, and tarsal bones.

• Knotless Tensioning System: Enables precise, incremental adjustment of the repair tension post-implantation. This ensures the ligament is restored to its anatomical tension without the risk of knot slippage or irritation.

• All-Suture "Soft" Construct: Composed entirely of high-strength UHMWPE (Ultra-High-Molecular-Weight Polyethylene) and FiberWire® material. Once deployed, the anchor expands against the cortex to create a secure, high-pullout-strength interface without the need for rigid plastics or metal.

• FiberViewer™ Deployment Indicator: Features a specialized suture tail that provides clear visual confirmation when the anchor has properly "bunched" against the internal cortex, ensuring secure fixation before tensioning.

• Minimal Bone Removal: The tiny 1.6 mm osteotomy reduces the risk of iatrogenic fractures and preserves options for future reconstructive procedures.
