“…This study confirmed previous findings on retrievals (Nakasone et al, 2015;Sugano et al, 2016;Tone et al, 2018) that no traces of MPC polymer remained on the bearing surfaces in any samples, not even in nonloaded areas, after short-term service in the human body.…”

“…In this study, we examined four additional short-term retrievals and sought a confirmation of our previous results, while also looking for further clarifications of the mechanism of MPC peeling off. Similar evidences were obtained by different research group on short-term retrievals (Nakasone et al, 2015), consistent with our previous studies (Sugano et al, 2016;Tone et al, 2018) in reporting the quick disappearance in vivo of the grafted polymer. Despite such a body of evidences on the tribological insignificance of the MPC technology in ameliorating the performance of artificial hip joints, the MPC-grafting approach continued to receive official appreciations (https://www.businesswire.com/news/home/ 20180625005394/en/).…”

“…In a previous paper (Tone, Hasegawa, Puppulin, Pezzotti, & Sudo, 2018), we examined short‐term retrievals and found that in none of three studied samples of retrieved MPC‐grafted liners, detectable MPC graft remained on the bearing surfaces although two samples yet contained remains of MPC polymer in their rim zones. We suggested that the MPC graft might have quickly disappeared from the bearing surface under in vivo loading, which is more severe than the in vitro one.…”

An analysis is presented of four short‐term retrieved highly crosslinked polyethylene (HXLPE) hip liners grafted with 2‐methacryloyloxyethyl phosphorylcholine (MPC) on their bearing surfaces, which were recently commercialized as a new generation of artificial hip joints. Straightforward evidences by X‐ray photoelectron spectroscopy (XPS) confirmed that the MPC layer peeled off on the bearing surface of all short‐term liners in both main wear and nonwear zones. Analyses by Fourier‐transform infrared spectroscopy with attenuated total reflection assessed the extent of surface oxidation and revealed the type of oxidative species. Electron spin resonance analyses, which compared retrievals and as‐received samples, revealed the presence of different species of alkoxyl CO• radicals. This study suggests that MPC grafts on polyethylene do not offer any additional protection from oxidation and can delaminate prematurely after short‐term in vivo exposure.

Crystalline Characteristics and Their Influence in the Mechanical Performance in Poly(ε-Caprolactone) / High Density Polyethylene Blends

et al. 2019

Blends of poly(ε-caprolactone) (PCL) and high-density polyethylene (HDPE) have been prepared at different compositions in order to assess the effect of HDPE on gas transport and mechanical behaviors of PCL. Previous to this evaluation, a complete morphological, structural, and thermal characterization were performed using techniques, including SEM, contact angle, FTIR, differential scanning calorimetry, and X-ray diffraction with synchrotron radiation at small and wide angles. Low HDPE incorporations allow interactions to be established at interfaces in the amorphous regions and the enhancement of the mechanical performance. Consequently, the addition of a small amount of HDPE (ranging from 5 to 10 wt%) appears to be appropriate in certain bio-applications where a higher mechanical behavior is required.
