Aside from testing new materials, Elvis is currently being adapted to replicate shoulder kinematics to develop a clinically-relevant wear gait model of the joint to better understand the relationship between shoulder designs and joint kinematics on wear. Ongoing work is focused on understanding the influence of fixation and conformity on wear and surface damage on UHMWPE. With our extensive library of retrieved shoulder devices, we are currently taking advantage of our damage assessment protocol and profilometry work to directly correlate damage reproduced in our laboratory simulator with in vivo damage seen on devices obtained from patients.
