Our lab has an extensive retrieval database of UHMWPE glenoids with various fixation designs. Many of these implanted glenoids have varying forms of damage after implantation in the body. Our lab has developed a scoring methodology for assessing macroscopic wear on retrieved UHMWPE glenoids. Information gathered from ongoing damage assessment of these implants is currently being statistically correlated with patient data, design variables, and surgical techniques to elucidate mechanisms of device failure in vivo.
