“…This film is ascribed to the intimate contact of the UHMWPE with the counterpart. The adhesive interaction between the bearing-materials can be quite high as proven by the occurrence of the transfer layer to the CoCrMo wheels [46] and the ordered crystalline structure within the polymer is destroyed. Underneath the film, a strong microfibrillar orientation was observed, shown in Fig.…”

No clear picture of the deformation and wear mechanisms of Ultra High Molecular Weight Polyethylene (UHMWPE) in artificial knee joints exists up to today. Tribological tests were conducted under relevant loads and the worn samples were extensively studied by XRD, DSC, Raman, and SEM. It was shown that stresses close to the surface in areas where high relative velocity in combination with high normal loads are applied are most effective in changing the microstructure and therefore most detrimental to produce wear particles, while in the depth the same deformed structure as under unidirectional cyclic loading is found. A model was proposed which reflects the deformation at different zones in the depth of a tribologically loaded UHMWPE sample. This model shows amazing analogy to the orientation of collagen fibrils in natural cartilage.

“…As demonstrated by other investigators, the presence of serum proteins initially serves to reduce adhesive wear; but upon their precipitation, adhesion increases [118]. Furthermore, it has been demonstrated that CoCr has a propensity for greater polyethylene adhesive wear than nitride-based materials [127]. Figure 3 presents comparative PE and XLPE wear data for gamma irradiated UHMWPE liners articulating against CoCr, ZrO 2 , Al 2 O 3 , and Si 3 N 4 femoral heads.…”

Abstract:The articulation performance of silicon nitride against conventional and highly cross-linked polyethylene, as well as for self-mated silicon nitride bearings, was examined in a series of standard hip simulation studies. Wear rates for polyethylene liners against silicon nitride femoral heads were consistent with reported literature, although higher than cobalt chromium controls. Excessive protein precipitation was a confounding factor in interpretation of the wear data. Post wear-test Raman spectroscopy of the cross-linked polyethylene liners showed no oxidative degradation. Wear of self-mated silicon nitride was found to be essentially zero and indistinguishable from alumina controls using continuously orbital hip simulation for up to three million cycles. However, introduction of an alternative loading profile from three to five million cycles, including a stop-dwell-start sequence, significantly increased wear for two of six silicon nitride couples. This behavior is associated with formation and disruption of a gelatinous silicic acid tribochemical film, and is consistent with a recurrent transition from fluid-film to boundary lubrication. Overall, these results suggest that silicon nitride articulation against dissimilar counterface surfaces (e.g., highly cross-linked polyethylene) is preferred.

“…5,6,9,27,28 Previously, cobaltchrome has been reported to have increased adhesive wear compared with oxidized zirconium on ultra-high molecular weight polyethylene. 17 More recently, cobalt-chrome has demonstrated reduced wear rates using this bearing surface, and highly crosslinked polyethylene has been recommended for younger patients undergoing total hip arthroplasty. [29][30][31][32] Our study demonstrates that excellent clinical outcomes are achievable with cobalt-chrome and oxidized zirconium femoral head articulations on a highly crosslinked polyethylene liner.…”

“…15,16 Tribiological testing has shown that oxidized zirconium has better wettability and less surface adhesion on polyethylene than cobalt-chrome. 17 Although the advantages and disadvantages of these bearing surface couples are well described, few studies have directly compared the bearing surface couples with respect to implant survivorship and clinical outcomes. Therefore, the purpose of this study was to directly compare age-, sexand body mass index (BMI)-matched cohorts of patients who received cobalt-chrome or oxidized zirconium on highly crosslinked polyethylene.…”

Background:The choice of bearing articulation for total hip arthroplasty in younger patients is amenable to debate. We compared mid-term patient-reported outcomes and survivorship across 2 different bearing articulations in a young patient cohort. Methods:We reviewed patients with cobalt-chrome or oxidized zirconium on highly crosslinked polyethylene who were followed prospectively between 2004 and 2012. Kaplan-Meier analysis was used to determine predicted cumulative survivorship at 5 years with all-cause and aseptic revisions as the outcome. We compared patient-reported outcomes, including the Harris hip score (HHS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Short-form 12 (SF-12) scores.Results: A total of 622 patients were followed during the study period. Mean follow-up was 8.2 (range 2.0-10.6) years for cobalt-chrome and 7.8 (range 2.1-10.7) years for oxidized zirconium. Mean age was 54.9 ± 10.6 years for cobalt-chrome and 54.8 ± 10.7 years for oxidized zirconium. Implant survivorship was 96.0% (95% confidence interval [CI] 94.9%-97.1%) for cobalt-chrome and 98.7% (95% CI 98.0%-99.4%) for oxidized zirconium on highly crosslinked polyethylene for all-cause revisions, and 97.2% (95% CI 96.2%-98.2%) for cobalt-chrome and 99.0% (95% CI 98.4%-99.6%) for oxidized zirconium for aseptic revisions. An age-, sex-and diagnosis-matched comparison of the HHS, WOMAC and SF-12 scores demonstrated no significant changes in clinical outcomes across the groups. Conclusion:Both bearing surface couples demonstrated excellent mid-term survivorship and outcomes in young patient cohorts. Future analyses on wear and costs are warranted to elicit differences between the groups at long-term follow-up.Contexte : Le choix de la surface d'appui à utiliser dans une arthroplastie totale de la hanche chez de jeunes patients ne fait pas l'unanimité. Nous avons comparé les résul-tats déclarés par les patients et la survie à moyen terme associés à 2 surfaces d'appui différentes dans une cohorte de jeunes patients.Méthodes : Nous avons étudié les cas de patients ayant reçu une prothèse de chromecobalt ou de zirconium oxydé couplé au polyéthylène hautement réticulé suivis de façon prospective entre 2004 et 2012. La méthode de Kaplan-Meier a été employée pour déterminer la survie cumulative estimée après 5 ans dans les cas où le résultat est soit la reprise toutes causes confondues, soit la reprise aseptique. Nous avons comparé les résultats déclarés par les patients, notamment au moyen du score de Harris (HHS), de l'indice WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) et des scores issus de la version courte du questionnaire d'évaluation de l'état de santé général SF-12.Résultats : Au total, 622 patients ont été suivis durant la période de l'étude. En moyenne, le suivi a duré 8,2 ans (plage de 2,0 à 10,6 ans) pour le chrome-cobalt et 7,8 ans (plage de 2,1 à 10,7 ans) pour le zirconium oxydé. L'âge moyen des patients était de 54,9 ± 10,6 ans pour le chrome-cobalt et de 54,8 ± 10,7 ans pour...
