Study and Analysis of Below Knee Osseointegration Prosthesis

Osseointegration is a medical metal implant into the residual bone of an amputated limb. The prosthesis can be connected to this implant. Different prosthetic components were thoroughly assessed using a mix of experimental testing and simulation results. The prosthetic foot's outstanding mechanical qualities were revealed during tensile testing on composite materials made of carbon and glass fibers. The mechanical properties of these materials yield stress Ϭy =70MPa, ultimate tensile strength Ϭult =162 MPa, and Young's modulus =2 GPa. For osseointegrated prosthetic components, the implant material yield stress Ϭy =470MPa, ultimate tensile strength Ϭult =558 MPa, and Young's modulus =2.7 GPa, Ti-13Nb-13Zr alloy, demonstrated excellent tensile and compression capabilities. Important information on both metallic and composite materials' durability under cyclic loads was obtained via fatigue testing. The numerical simulations were carried out utilizing the ANSYS 17.2 program. The analysis shows the safety factor for a prosthetic model with below knee osseointegration is 1.563. So that the Von-Mises stress and total deformation were acceptable. The integration of actual data, such as the results of tensile, compression, and fatigue tests, with numerical simulations, highlights the significance of materials and mechanical analysis in developing prosthetic technology, promising improved mobility and quality of life for amputees.
