ABSTRACT The use of endo-exo prosthesis is an alternative to improve the quality of life of amputees, allowing correct distribution of body weight, reducing skin problems and pain related to the implant, and reducing lameness. The aim of this paper is to report the use of a fixed bilateral endo-exo femur prostheses in a cat with amputation prior to treatment. The endoprostheses were made with titanium and the exoprostheses were made with 3D printing technology. A longitudinal craniolateral surgical approach was used and the skin incision was made over the knee-joint, then fascia lata incision, followed by biceps femoris and vastus lateralis muscles retraction, incision through the joint capsule to expose the tibiofemoral joint, disarticulation, and tibia and fibula removal. Afterwards, a femoral leveling osteotomy and insertion of the implant in the medullary canal were performed, being attached in the cis and trans cortical bone. The patient was evaluated in the immediate post-operative and periodically thereafter, showing satisfactory results, without macroscopic signs of rejection, wound dehiscence or infection, fracture, or injury of limbs, and presented adapted walking. Furthermore, it was observed the return to common behaviors for the species.
