Acoustic emission (AE) technique has been investigation for identification and location of osteoarthritis in knee joint. Although, AE technique has widely been used for years as a NDT tool in damage monitoring and condition inspection of industrial and structural materials, similar applications of AE technique has been considered in integrity analysis of knee joint as well. Of course, integrity analysis of knee joint involves a detail study of several anatomical parts of knee joint like bones, cartilage, tendons etc. However, the interest of the present investigation has been confined to knee osteoarthritis which is considered to be caused due to the degeneration of knee cartilage. The incidence of this widely manifested knee disease increases in aging society. The major concern of this disease is its incurability at its matured stage. However, early detection for adopting appropriate measures can reduce the risk of this disease. The present investigation focuses on the dynamical behavioral characterization of knee joint for its integrity analysis with acoustic emission characterizing parametric features of AE signals. Data has been collected from the participants with different age groups without any knee problems as well as with knee problems (OA). All data have been clarified for identifying the technique as a clinical tool in monitoring knee condition effectively.
