HYALOFAST®: A Hyaluronic Acid Based Matrix Supports Regeneration of Hyaline-like Cartilage

One-Step Regeneration Made Easy

HYALOFAST is a non-woven 2×2 cm or 5×5 cm biodegradable hyaluronic acid-based scaffold for hyaline-like cartilage regeneration. It is used for the entrapment of mesenchymal stem cells (MSCs) to arthroscopically treat both chondral and osteochondral lesions.

Unlike other multi-layered collagen or synthetic products, HYALOFAST is composed of a single 3D fibrous layer of HYAFF®, a benzyl ester of hyaluronic acid (HA), a natural component of the extracellular matrix. It can be cut and adaptively fit into irregular lesions aided by its soft and non-woven structure. HYALOFAST can be implanted in mini arthrotomy or arthroscopic surgery in any orientation or stacked due to its single uniform layer of HYAFF. Once implanted, it maintains its structure to support MSC attachment, proliferation and differentiation to completely fill the lesion. As HYAFF degrades over time, it releases hyaluronic acid into the lesion and forming an embryonic-like microenvironment rich with HA.

Clinical data indicates that HYALOFAST delivers positive results, enabling patients to regenerate hyaline-like cartilage with the goal of helping them return to daily activities naturally.1

The HYALOFAST Advantage

Clinically Proven

  • Chondral & Osteochondral Solution: In combination with HYALOFAST, MSCs have shown to differentiate into chondrocytes for hyaline-like cartilage regeneration1 & osteocytes for subchondral bone formation3
  • Clinically Effective: Several HYALOFAST publications demonstrate effective outcomes in knees4,5,18,19,20,21,22 and ankles6,17 with over 8 years of follow-up data

Unique HYAFF Composition

  • Embryonic-like Environment: As HYAFF fibers degrade, hyaluronic acid is released into the lesion, creating an embryonic-like microenvironment rich with HA
  • Bio-resorbable: Hyaluronic acid is a natural and major component of human cartilage and is highly biocompatible. Once the HYAFF degrades into HA, it is naturally resorbed into the body.
  • Strong Safety Profile: HA is sourced from bacteria, so HYALOFAST is not an animal-based product. HYAFF has been used in the tissue regeneration field for more than 15 years with an excellent safety and efficacy profile.2


  • Versatile: Can be used as a chondroprotective coverage after microfracture, or in combination with bone marrow aspirate concentrate to treat chondral & osteochondral lesions via a one-step procedure
  • Flexible Application Options: Can be applied via arthroscopy or miniarthrotomy without requiring additional fixation in most cases, given its naturally adherent properties
  • Adaptive Fit: Given its soft texture, HYALOFAST conforms, covers and fills both regular and irregular lesions. Due to its uniform single-layer structure, the scaffold can be applied in any orientation or stacked.


HYALOFAST is CE-marked as a biodegradable support for the entrapment of mesenchymal stem cells for the repair of chondral and osteochondral lesions. It acts as a support for bone marrow aspirate or as a chondroprotective coverage which favors in situ residence of mesenchymal stem cells after their mobilization due to microfracture or perforation procedures.

For additional details and information about the product, please refer to the Instructions for Use that are included in the product’s packaging or refer to the HYALOFAST website.

HYALOFAST is not approved for use in the United States.
