Research Projects

  • Orthopaedic implant failure analysis

    Orthopaedic implant failure analysis

    Implant failure analysis in the Dartmouth Biomedical Engineering Center for Orthopaedics is ongoing and plays a key role in identifying failure modes and relating them to various designs and materials being used in the industry. In fact, in 2000, NIH's Consensus Development Program produced a technology assessment statement acknowledging the value of implant retrieval programs:

    • Implant retrieval and analysis is of critical importance in the process of improving care of patients in need of implants.
    • Attention needs to be directed toward reducing various obstacles to implant retrieval and analysis, particularly legal and economic disincentives.
    • The failure to appreciate the value of implant retrieval and analysis is a serious impediment to research in devices. A focused educational program will provide the information necessary for improving the quality of future devices.

    See more about implant failure analysis.

  • Knee/shoulder implant bearing function

    Knee/shoulder implant bearing function

    Bearing function of retrieved knee devices sent to us by orthopaedic surgeons are assessed for damage, and also quantitatively assessed for wear. Dimensions of retrievals are compared to design specifications or shorter in-vivo duration devices to calculate both articular and backside wear. Wear and wear rate are correlated with variables including polyethylene pedigree, articular bearing geometry, device fixation, and patient factors.

    Current work also includes examination of a series of reverse and total shoulders to determine the incidence of abrasive and adhesive wear and determine typical locations for these wear patterns on polyethylene components.

    See more about knee/shoulder implant bearing function.

  • Joint replacement bearing material behavior

    Joint replacement bearing material behavior

    Material behavior of medical grade ultra-high molecular weight polyethylene (UHMWPE) was identified as a serious concern as it limits the overall lifetime and success of a joint replacement. Although total joint arthroplasty involving UHMWPE as a bearing surface has been one of the most successful procedures of the last century, issues of wear, oxidation, and fatigue failure remain obstacles to the longevity of joint replacements.

    See more about UHMWPE material behavior.

  • Biomechanics analysis and monitoring

    Biomechanics analysis and monitoring

    Biomechanics analysis and monitoring following joint arthroplasty is valuable for achieving optimal recovery. Our laboratory has developed and implemented a novel method for monitoring continuous long term joint function using inertial measurement units (IMUs). Prospective studies are in progress to compare knee and shoulder function before and after arthroplasty. This data can be compared to a cohort of healthy individuals with no known joint arthropathy.

    See more about biomechanics.

  • New materials for orthopaedic implants

    New materials for orthopaedic implants

    New materials research and development for orthopaedic implants includes:

    • Evaluation of equal channel angular extrusion (ECAE)-processed ultra-high molecular weight polyethylene (UHMWPE) for joint arthroplasty and industrial applications;
    • Investigation of off-label use of a resorbable calcium sulfate antibiotic carrier in single stage and two-stage procedures to determine the potential of this use to change damage patterns or wear rates of artificial joints.

    See more about new materials.

  • New devices for total joint arthroplasty

    New devices for total joint arthroplasty

    New devices research and developent for total joint arthroplasty includes:

    • Testing of a new bi-material bearing for a total hip arthroplasty (THA) device against conventional bearing designs to compare levels of bearing surface damage and wear;
    • Development of an intraoperative method for quantifying the orientation of prosthetic components used in total knee arthroplasty (TKA) that is efficient, easy to use, cost effective, and quick with respect to total surgical time.
