Finite element analysis of patellofemoral joint prosthetics

Abstract

Prosthetics have been existed from the times of the old. Prosthetics were utilized numerous applications: work, restorative appearance and aesthetics from time of the Egyptians, profound feeling of being entirety. Chronic knee conditions such as Chondromalacia patella is one of the knee joint is an disability that influences the ligament of the patella and is additionally regularly called sprinters knee. It cause torment on the patellar part of knee and furthermore require supplanting medical procedure for influenced knee with counterfeit segments. Kneecap typically dwells over the front of your knee joint. At the point when you twist your knee, the posterior of your kneecap floats over the ligament of your femur, or thigh bone, at the knee. Ligaments and tendons connect your kneecap to your knee thigh muscle. At the point when any of these parts neglects to move appropriately, it can make your kneecap rub facing your thigh bone. The substitution of the entire knee is a tedious and maximally obtrusive procedure. Hence forth a patellofemoral embed can help in just be restricted cure but then take care of the issue caused due to chondromalacia. The patellofemoral CT images will be segmented and smoothed using MIMICS 21.0 software. This allows for meshing and assigning material properties to the bone to check how the bone interacts with the implants. Material properties are assigned using ANSYS Mechanical APDL 18.The mechanical properties of two implant materials are compared to view the results. The scope of the project is that it is beneficial in the prosthetic industry as it can provide patients with the less painful method of replacement and hence they will be able to do their normal daily activities. Which can be for the betterment of athletes and runner and other targeted condromlacic patients. The aim is to carry out Finite Element Modeling and analysis of Prosthetic for patellofemoral region. The objective is to carry out segmentation and thresholding of a CT image. Studying the various material properties that will used for prosthesis for the Patellofemoral region and to undertake a comparative Finite Element Analysis of the compatible materials. The comparison between bio-compatible materials like carbon fiber and HDPE and check as to which would be the better implant material, its feasibilty and availability and also to design and create a 3D model of the is the main aim of the study.
