“…The current study of dual mobility components suggests their in‐vivo wear may potentially be below this threshold. The metal‐on‐highly crosslinked polyethylene control group in this study has reported in‐vivo wear rates significantly lower than this threshold at 0.015 mm/year and 0.001 mm/year at 5 years follow‐up, and the results of this hip simulation suggests that volumetric wear rates of dual mobility components are comparable to the wear rates of metal‐on‐highly crosslinked polyethylene bearings in this study. In addition, Devane et al has previously reported that in cementless cups, the osteolysis rate was 49% for volume wear rates of 155.1 mm 3 /year, while a 12% incidence of osteolysis with volumetric wear rates of approximately 99 mm 3 /year was reported with cemented designs .…”

Steep cup abduction angles with adverse joint loading may increase traditional polyethylene bearing wear in total hip arthroplasties. However, there have been few reports evaluating the effect of cup inclination on the wear of dual-mobility devices. In a hip joint simulation, we compared the short-term wear of two-sizes of modular highly cross-linked dual-mobility bearings (28 mm femoral head diameter/42 mm polyethylene insert outer diameter/54 mm acetabular shell diameter; 22.2 mm femoral head diameter/ 36 mm polyethylene insert outer diameter/48 mm acetabular shell diameter) at 50 and 65˚of cup inclination with modular 28 mm femoral head on 54 mm cup diameter metal-on-highly cross-linked polyethylene bearings. Increasing inclination from 50-65˚had no changes in volumetric wear of 28/42/54 mm (mean, 1.7 vs. 1.2 mm 3 /million cycles, respectively; p ¼ 0.50) and 22.2/36/48 mm (mean, 1.7 vs. 1.2 mm 3 /million cycles, respectively; p ¼ 0.48) dual mobility bearings. At 65˚, 22.2/36/48 mm dual-mobility bearings had lower volumetric loss (mean, 2.2 vs. 6.3 mm 3 ; p ¼ 0.03) and wear rates (mean, 1.2 vs. 2.7 mm 3 /million cycles; p ¼ 0.02) compared to metal-onhighly cross-linked polyethylene bearings. Modern-generation dual-mobility designs with highly cross-linked polyethylenes may potentially withstand edge-loading from steeper cup-inclinations without substantial decreases in wear. ß

“…The investigated sequentially HX-PE showed excellent wear behavior in simulator studies [5,15] and first promising clinical outcomes [16,17]. However, despite good wear results, the thin liner thickness should not be underestimated concerning liner failures.…”

“…These results compare favorably with those of reports of annealed and re-melted HXLPEs with 5 to 10 years of follow-up ( Table 2). 4,13,14,[22][23][24][25][26][27][28] The 5 studies in which re-melted HXLPE was implanted report a range of positive wear from 0.005 to 0.040 mm/y. [22][23][24][25][26] One of the studies reported negative wear (-0.012 mm/y).…”

A once annealed highly cross-linked polyethylene (HXLPE) was introduced in 1998. Concerns regarding its long-term performance and oxidative resistance exist because of the presence of retained free radicals. The authors studied 48 patients with 50 hip implants having an average age of 62 years. They were followed for 9 to 15 years. The purpose of this study was to determine linear wear rate and the incidence of osteolysis and/or mechanical failure. At an average follow-up of 12.2 years, the annual linear wear rate was 0.018 mm (SD, 0.024 mm). No mechanical failures or osteolysis have been found to date. The clinical performance of this HXLPE continues to meet expectations despite the presence of free radicals. [Orthopedics. 2016; 39(3):e565-e571.].

Low Wear of a Second-generation Highly Crosslinked Polyethylene Liner: A 5-year Radiostereometric Analysis Study

Abstract: The head penetration of a second-generation XLPE liner remained low at 5 years and the wear rate calculated after the first year was low in all directions. This low level of wear remains encouraging for the future clinical performance of this material.
