Total knee prosthesis

Virág, the 2-year-old Yorkshire terrier hosted by Állat és Ember Állatvédő Egyesület \[“Animal and Human” Animal Protection Association], was first admitted to FuzioVet Animal Hospital because of the serious lameness of her left hind leg. So, Dr Antal Seregi carried out lameness examination on her. Her condition was diagnosed as serious limb malformation due to the congenital deformity of the left femur and the left tibia resulting in a fourth-degree medial patellar luxation - the inward dislocation of the patella. This was the cause of her lameness. The serious limb deformity necessitated the mapping of the ill bones, by performing CT scan after the classical X-ray examination. By doing so, it was possible to obtain a detailed image of the deformation. After the CT scan a team of professionals analysed the images with our vet colleague, Dr Kálmán Czeibert, and drew the conclusion that the bones in the limb shall be 3D printed so that the team can specify the precise details of the planned operation. In Hungary this was the first complex orthopaedic operation whose planning involved printed bones as well. The first operation aimed at correcting the deformity of the femur and the tibia so that the structure of the bones improves. However, Virág’s limb usage was not significantly better at this stage after the operation. It could be explained by her two years of age - the atrophy of her muscles evolving in the course of this period of time - and the malformation of the ligaments in her knee. As a result, we had to come up with an operation solution which provides Virág with the ability to fully use her knee and to live a painless life. This was the moment when we decided to design a total knee prosthesis customised to Virág’s needs ensuring that this prosthesis fits her faulty bones as much as possible. We considered several factors in the course of the 6 months of planning. We also dived into the 3D printing of medical implants in titanium and we planned all the steps of the operation, which took place in February 2023. The operation was smooth and everything went according to plan. Then, on the 4th day after the operation the most difficult period of the healing process started: rehabilitation. The physiotherapists at Ebfizio treated Virág twice a week and massaged her leg four times every day which resulted in her excellent limb usage three months after the operation. Nevertheless, Virág is not fully healed yet because stopping the atrophy of her muscles, enhancing the mass of her muscles and the easement of the contracture occurring in the course of 2.5 years still require plenty of time and energy. However, Virág does not simply endure these treatments, she loves them.

Neurological problems and innovations in their treatment - Interview with Dr László Lehner, DVM (Part 1)

If you experience sudden muscle twitches or movement problems in your cat or dog, it can immediately scare you. Fortunately, however, small animal neurology is continuously developing which is greatly supported by our developments as well.  In this episode of our interview series we are talking to Dr László Lehner, a veterinarian specialised in small animal neurology, who carries out numerous operations regarded as unique in Hungary, e.g. removing...

The TROCA 55 trochlear cap system - Customised trochlear cap by LimesVet

One of the most frequent orthopaedic deformation in small dogs is the dislocation of the patella. Patellar luxation is often a congenital, inherited disorder but it can also be caused by a trauma or an accident. With the help of 3D design and printing, we have created an implant which is considered exceptional worldwide. It is uniquely designed and manufactured for the femur of the given animal. We deliver this product together with anatomical models...

Integrating LimesVet services into veterinarian praxis

Today it is obvious that the appearance of 3D technology in the field of medicine opens new horizons for medical professionals in treating diseases. Currently we are just getting to know the advantages of this technology. However, thanks to the rapid development in this field, the question arises as to how to integrate all these achievements into the daily healing practice.
