On design and fabrication of 3D printed stifle prosthetic implant

In the past decade some studies have been reported on the use of customized 3D printed stifel prostheses (SP) for addressing patella luxation (PL) in canines. But hitherto limited solutions are available for PL issues for all age groups/breeds of canines. In this work, a case study has been presented for the design and fabrication of a novel 3D printed solution that may be suitable for all ages/breeds of canines to address the PL issues. The static structural analysis (on the ANSYS platform) revealed that an assembly of the implant (SP) is safe to bear the load at 600 N, with a maximum displacement of 0.015 mm and maximum Von-Mises stress of 25.657 MPa. Further residual stress and boundary distortion study was performed for qualitative analysis, which also supports the safe design for the fabrication of SP. The results are also supported by photomicrographs, porosity%, grain size No., and surface characteristics analysis based on scanning electron microscopy (SEM).
