The tear of the anterior cruciate ligament is still one of the most common orthopaedic diseases in dogs. The path of the many surgical methods developed for this led via intracapsular and extracapsular techniques to modern corrective osteotomies that alter the geometry of the affected knee joint. With the development of new materials in medical technology, it is now possible to replace the anterior cruciate ligament in an anatomically correct manner, instead of changing the forces acting on the joint.
The Zlig consists of ultra-high-molecular polyethylene with the special feature that the woven structure of the implant is interrupted intra-articularly be “free fibres”. Free parallel fibres reduce fatigue and also encourage the ingrowth of fibroblasts and collagen. Each implant is delivered in a sterile packed sleeve, making it easier to handle the implant before it is inserted into the joint. A selection of sizes with different resistances and fibre lengths are available to fit different patient sizes.
