KNEE IMPLANT FOR TOTAL KNEE
REPLACEMENT
Total knee replacement is the most effective treatment to relief pain
and restores the normal function in a diseased knee joint. The aim of
this research was to develop a patient-specific knee implant which can
be fabricated using 3D Printing also called as additive manufacturing
techniques. 3D printing is an emerging technology and its use in Ortho-
paedics is slowly gaining acceptance. This technique makes it easy to
manufacture patient specific devices/guides and instrumentation of any
shape and size. The patient-specific technology improves on convention-
al of the shelf process by allowing considering each patients anatomical
structure, shape and size. In this study patient specific knee implant de-
sign, simulation and 3D print is discussed. In particular we want to high-
light the role of computer simulations in testing and optimizing patient
specific device. Patient knee CT scan data was modelled in Image Sim
software and 3D model was generated. This model was used as the base
model to capture the outer shape of distal femur and proximal tibia. Full
set of J curves of condyles were captured and then exported. These set
of J curves along with other landmarks were imported in solid works and
full implant for femur , tibia components and insert were designed. A de-
tailed total knee-joint FE model was created in order to predict stress and
strain at various flexion angles. Results from these simulations highlight-
