Development of patient specific knee joint implant

Abstract

The main objective of this paper is to generate 3D model of knee from Digital Imaging and Communication in Medical (DICOM) files, which is acquired from CT scan. Now a day so many cases of Total Knee Replacement (TKR) are happens due to various reasons and after TKR, patient satisfies 90% to 95% as reported. In preoperative planning saves the time and boosts the knee replacement surgery and it includes 3D model of knee, which is essential for further prediction of operative decisions. The purpose of this work was to form a procedure for generating 3D solid model of the human knee to be used in an ongoing preoperative planning. 3D Solid models of the distal end of the femur and the tibial plateau were created to approximate the human knee. So, in this work many open source data conversion software’s are used for transformation of DICOM files to Stereo-Lithography (STL) model. Solidworks software gives significant contribution to produce 3D solid models from the scanned data. This 3D model of knee is used for customization of knee implant according to damaged portion of actual knee or required dimensions.
