What is Zlig?
Zlig is an artificial implant designed to replace a torn Anterior Cruciate Ligament (ACL) in dogs. Unlike other procedures that modify how the knee operates to handle an ACL tear, Zlig offers a direct ACL stabilisation method.
This approach is the standard for humans and is becoming increasingly advocated for dogs. Thanks to recent advancements, Zlig implant surgery now presents fewer health complications and provides enhanced joint strength and stability.
Molly’s recovery post-surgery was fairly easy, involving rest and toilet walks only for 4 weeks. Then, for the next 4 weeks, the length of her walks was increased before she was able to go full off lead again.
How does a Zlig ACL implant work?
Constructed from materials similar to those in the LARS procedure for humans, the Zlig implant serves as a durable substitute for a torn ACL. This implant is specifically designed to be seamlessly integrated into the joint, with its unwoven section promoting the growth of fibroblasts, making it as close to a natural ACL as possible.
Secured with four screws in drilled boney tunnels, this implant ensures minimal infection and fracture risks, given that no bone is removed during the process.
Recovery and aftercare
Dogs can use their leg post-surgery, but we recommend cage rest and short toilet walks for the first month to promote optimal knee recovery. This is followed by another month of lead walks and cage rest before the pet can fully engage in off-lead activities.
We ensure that our orthopaedic patients receive adequate pain management during and after the surgery, with most pets able to recover in the comfort of their homes on the same day of the procedure.
Benefits of Zlig over other ACL treatments in dogs
Zlig stands out because of its unique capability to address the medial rotational instability caused by an ACL tear. It offers a comprehensive stabilisation of the knee, mimicking the natural angling of the ACL.
Unlike other ACL procedures that may result in arthritis within a few years, Zlig potentially offers a more stable and long-lasting solution. However, it's worth noting that Zlig is primarily designed for dogs weighing between 5-45kg.
For larger dogs, the suitability of the implant depends on their activity and load on the joint. Double implantation might be a consideration in some cases, although this can affect the overall cost.
Cost of Zlig ACL replacement surgery for dogs
Our current Zlig Implant Surgery cost is $3,000 to $3,400.
Zlig implants offer dogs with torn ACLs improved mobility and strength without the need to modify or cut bones.
Although the procedure might take longer and Zlig implants carry a higher price tag, the overall benefits outweigh the initial costs. Investing in an ACL replacement can potentially decrease the risk of early-onset arthritis in your dog's lifespan.

Molly – 2 Year Old Labrador Diagnosed with a Torn ACL
The joint was closed using absorbable sutures, then the skin was closed using absorbable ford interlocking. An x-ray of the lateral stifle was taken post op. The area was bandaged using melolin/vetwrap stik with IV fluids and fentanyl infusion continued.
Molly was able to go home later that day with strong medication to help her manage the pain (including clay tablets, gabapentin capsules, trazodone capsules, metacam oral medication and Zydax injections).
Since childhood, Dr. Plummer has been passionate about caring for animals, and graduated with Honours in a Bachelor of Veterinary Science from the University of Queensland. He opened the Brisbane Pet Surgery with the aim of making quality pet care affordable for everyone.
