Abstract
An arthritic knee affects the patient‟s life by causing pain and limiting
movement. If the cartilage and the bone surfaces are severely affected, the
natural joint is replaced with an artificial joint. The procedure is called
total knee arthroplasty (TKA). Lately, the numbers of implanted total
knee prostheses grow steadily.
An important factor in TKA is the perfect alignment of the total knee
prosthesis (TKP) components. Component misalignment can lead to the
prosthesis loss by producing wear particles.
The paper proposes a study on mechanical behaviors of a TKP based on
numerical analysis, using ANSYS software. The numerical analysis is
based on both the normal and the changed angle of the components
alignment.
