  • Self-powered instrumented knee implant for early detection of postoperative complications
    2010
    Co-Authors: S. Almouahed, M. Gouriou, E. Stindel, Chafiaa Hamitouche-djabou, C. Roux
    Abstract:

    In-vivo measurement of tibiofemoral forces transmitted through Total Knee Replacement (TKR) during normal walking allows the early detection of postoperative complications such as the tibiofemoral misalignment and soft-tissue imbalance. In addition, the in-vivo data can help to improve the design of TKR in order to reduce polyethylene wear and consequently to increase the lifespan of knee implant. A self-powered custom-designed tibial implant instrumented with four piezoceramics has been developed in order to detect the aforementioned complications by measuring the relative change in Pressure Center (COP) position for different levels of eccentric compressive loading. Moreover, the energy harvested by the piezoceramics can be used to power a transmission system located at the stem of knee implant to wirelessly transmit the in-vivo data outside the implant for further processing and display.

  • Finite element study for intra and postarthroplastic evaluation of ligament balancing in standing position using instrumented tibial baseplate
    2009 IEEE International Symposium on a World of Wireless Mobile and Multimedia Networks & Workshops, 2009
    Co-Authors: S. Almouahed, M. Gouriou, C. Hamitouche, E. Stindel, C. Roux
    Abstract:

    To obtain a long lifespan of knee joint implant, it is indispensable to balance the collateral ligaments of the knee and to restore a correct alignment of the mechanical axis of the lower limb during total knee replacement (TKR). Nowadays, a proper mechanical axis alignment of the lower limb is guaranteed by computer assisted orthopaedic surgery (CAOS). To assure a symmetric laxity of these ligaments, a smart tibial baseplate instrumented with three strain gages could be used. Our objective is to study the displacement of the Pressure Center as a function of ligament balancing represented by the shift of resultant axial force exerted by the two condyles of the femoral component on the tibial tray. Improving the surgeon perception helps to solve the ligament balancing problem. Our first instrumented tibial baseplate has been modeled using ANSYS Workbench 11. As a result, soft tissue balance is possible to be assessed using the Pressure Center position. In this paper, we present our approach and the preliminary results of instrumented tibial plateau model which would be validated later by the first prototype.
