A painful problem.
To help Oreo, OIC obtained a donated patella that was used to generate a scaled digitized copy. A biomedical engineer then converted the file into a computer-aided design (CAD) model. X-ray radiographs of Oreo’s other patella were then used to modify the CAD design to match his femur.
“In Oreo’s case, we were able to produce a custom-tailored implant in only four days including design, analysis, physical testing, and manufacturing. As we move down the learning curve, it will probably be possible to produce similar implants in only a day or two.”

Oreo recovered without incident, and eight weeks after his surgery, he had regained complete function of his leg with a full range of motion and weight- bearing capacity. His owner reported that he could once again go on long walks and jump using both of his limbs. Now, more than three years later, Oreo continues to enjoy an active lifestyle without complications thanks to his 3D printed implant.
“FDM is an ideal technology for implant manufacturing because it is capable of producing strong, durable, biocompatible parts with the right physical properties,” said Martin Petrak, president of Orthopaedic Innovation Centre.
“With FDM, we can tailor the implant to perfectly match the recipient’s anatomy which has the potential to provide dramatic improvements in functionality and recovery time.”
