Free fibers

Unique technology that makes all the difference

background image
Implanted intra-articularly, the free fibers are specifically engineered to meet the complex biomechanical demands of the joint. They provide resistance to combined tension, flexion, and torsion forces, with minimal structural degradation over time. Unlike braided structures, they do not shear or elongate, and generate no particle release into the joint—ensuring long-term integrity and safety throughout the animal’s life.

Testimonials

Out of more than 5,000 dogs treated, here is a selection of feedback from veterinary surgeons and pet owners.

Rex

2016

"Rex is very playful and energetic. After he tore the cruciate ligament o, his right side in 2016, my vet suggested a still-experimental technique that carried very few risks because it wasn’t irreversible. It was especially well-suited for active dogs, as it allows for a fast recovery. We have a large garden, and Rex loves being outdoors and going on long walks, so after doing some additional research, I decided to go ahead with it. In 2017, he tore the cruciate ligament in his left leg. Given the excellent results of the first surgery in 2016—with no issues at all and Rex still as lively as ever—I immediately asked for the same technique to be used again. Now, three years after the first surgery and two years after the second, Rex is still just as active and shows no aftereffects from either procedure. I’m very happy that my dog was among the first to benefit from this new technique, and I hope his case can inspire others!"

Chipie

2018

"My vet suggested a new technique to reconstruct the cruciate ligament, and I was immediately convinced by both the concept and the benefits it offered. After undergoing cranial cruciate ligament reconstruction with a synthetic ligament, Chipie recovered very quickly and hasn’t had any issues since. I highly recommend this technique, which from an owner’s perspective, has only advantages — and I’m pretty sure my dog would say the same!"

Paput

2018 et 2019

"Among the options my vet presented, I chose the ligament reconstruction technique using a synthetic ligament, which seemed more logical and natural to me compared to other available methods. My dog is a 62 kg male who enjoys being outdoors, even if he’s not the most active. The immediate results and the ease of managing postoperative care quickly gave me confidence. I have absolutely no regrets. Paput underwent two reconstructions a year apart, and today he’s in great shape. Based on my experience and the results I’ve seen, I can wholeheartedly recommend this technique!"

Round ligament reconstruction assisted by a C-arm

2025-06-12

Ulcko, a 7.5 kg Pomsky, was treated by the surgical team at CHV AniCura Aquivet following a polytrauma, including an open dislocation of the left tarsus and a right coxofemoral (hip) luxation.Thanks to a minimally invasive surgical approach guided in real-time by fluoroscopy, Drs Geoffrey Pagès, Paula López de la Oliva Cases, and Mia Gobin were able to accurately place the H-lux® 25 fibers (3 125 N) implant from STIF – Pet Care.✅ Result: a faster procedure (25 minutes), a less invasive technique (no joint opening required), and optimized recovery for the patient (video taken 3 days post-op).This type of intervention demonstrates how next-generation implant technologies and advanced imaging (here, C-Arm) continue to transform the treatment of orthopedic conditions.Congratulations to the entire veterinary team for this excellent technical and medical collaboration!

Training session dedicated to the use of Z-lig®

2025-04-07

Recap of Our Training on Using Z-lig® for Cranial Cruciate Ligament ReconstructionThe 6th of April, participants had the opportunity to:Discover the strong legacy of STIF – Pet Care in human surgery and its expertise in veterinary orthopedics.Explore the evolution of our free fibers technology, specifically adapted for veterinary surgery.Learn more about current and potential applications, and practice the cranial cruciate ligament reconstruction technique in dogs. In the morning, participants focused on theory and discussion around the fundamental principles.In the afternoon, hands-on work on anatomical specimens: participants performed a cranial cruciate ligament reconstruction in dogs, carefully reviewing each technical step to master all the essential aspects—especially the details that optimize post-operative recovery and ensure long-term stability of the results.A warm thank you to our instructors, Drs. Antonio Munhoz & Geoffrey Pagès (Dipl. ECVS), for their expertise and teaching skills, and to Neo Animalia for its commitment to high-quality training.📆 Upcoming sessions in this format: September 27 (EN) & September 28 (FR), 2025 📍 Louvain-La-Neuve 📩 Registration is open : sign up now.

The advantages of free fibers

2025-07-16

Free fibers offer two major advantages.1. Mechanical resistance:In the active zone of the implant (Z-lig®), the residual fatigue resistance (combined tension, flexion, and torsion) of free fibers is significantly higher than all other tested structures (12 million cycles), whether woven, knitted, or braided, which degrade more or less rapidly (structure elongation) and release debris into the joint before mechanical failure.Free fibers produce no particle debris, and elongation after this testing phase was approximately 2%. 2. Promotes fibroblast colonization and growth of new collagen aligned with the direction of tensionThe architecture of free fibers is porous and conducive to fibroblast infiltration (unlike braided structures, which are dense, opaque, and minimally permeable). When a healthy remnant of the cranial cruciate ligament (CCL) is present, it should be preserved as much as possible, as it facilitates fibroblast regrowth and the development of collagen oriented along the direction of tension.
