Research Facilities and Tools


Implant retrieval and related clinical performance studies are conducted primarily in Wearn 511, located within University Hospitals Cleveland Medical Center.  Some examples of our facilities and tools are shown, below. 

Retrieved total hip and total knee replacements are received from the Department of Pathology following revision or removal surgery at University Hospitals.  All devices are thoroughly cleaned prior to analysis. 

After cleaning, all retrieved devices are initially assessed for damage using a stereomicroscope.

Retrieved devices are then thoroughly photo-documented to accurately record their condition following explantation. 

All retrieved devices are stored in a secured access laboratory and are cataloged using a de-identified alpha-numeric code A  -80C Freezer is used to store all explanted ultra-high molecular weight polyethylene components to minimize further oxidative degradation following explantation.


An X-ray Scanner allows for the digitization of historical radiographs. Hip Analysis Suite Software is used to evaluate the extent of in vivo wear of total hip replacement acetabular components. 


Fundamental mechanical and materials characerization studies are conducted primarily in the  Orthopaedic Bioengineering Laboratories, located on the 6th floor of the Glennan Building in the Case School of Engineering.  Some examples of our facilities and tools are shown below.


Access to CWRU's shared facilities such as The Swagelok Center for Surface Analysis of Materials (SCSAM) are also a valuable resource for additional materials surface characterizations. 

Scanning electron microscopy allows for the examination of fracture mechanisms during static loading and fatigue.  Shown here are images of microvoid coalescence occurring during crack initation from a blunt notch in ultra-high molecular weight polyethylene.
