“…Concerning hip prosthesis, head-cup joint for instance, some previous investigations [12] were carried out to evaluate the lifetime of a PEEK CF cup against a head made of metal or alumina. PEEK CF highlights the advantage to be not degradable after sterilization, especially  radiation, a requirement for implanting a biomaterial [13].…”

International audienceThis study is focused on performing tribological tests on new materials for orthopaedic implants applications, PAEK (poly aryl ether ketone) polymer group. The experiments were performed in physiological liquid, at 37 °C, for simulating the human body fluid. PAEK's tribological properties that are wear rate of polymers and wear mechanisms on common metallic alloys used as orthopaedic implants: Co-Cr, 316L SS and Ti-6Al-4V are compared to the gold standard used for hip joint prosthesis, the UHMWPE (ultra high molecular weight polyethylene) on the same metal alloys. PEEK (poly ether ether ketone) and PEKK (poly ether ketone ketone)/CF (carbon fibers) show the lowest wear rate on every counter metallic material; the system UHMWPE on any metal alloys exhibit the highest wear rate although having the lowest friction coefficient. From microscopic images and the evolution of the friction coefficient, a wear mechanism was suggested for each polymeric material

“…Achieving a stable bone-implant interface by osseointegration has been a longstanding problem with carbon-fiber-reinforced polymer materials, including CFR/PEEK. 17,18 To date, studies have focused on wear reduction 4,19 or secure implant fixation [20][21][22][23][24][25][26][27] to develop cementless CFR/PEEK prostheses. Given that CFR/PEEK is bio-inert, the addition of bioactive material coatings has been considered to improve osseointegration.…”

Despite the excellent osseointegration of carbon-fiber-reinforced polyetheretherketone (CFR/PEEK) with a surface hydroxyapatite (HA) coating, the bone-implant interfacial shear strength of HA-coated CFR/PEEK after osseointegration is unclear. We examined the interfacial shear strength of HA-coated CFR/PEEK implants after in vivo implantation in a rabbit femur-implant pullout test model. HA coating was performed by a newly developed method. Uncoated CFR/PEEK, HA-coated blasted titanium alloy, and uncoated blasted titanium alloy were used as control implants. The implants were inserted into drilled femoral cortex, and pull-out tests were conducted after 6 and 12 weeks of implantation to determine maximum interfacial shear strength. The HA-coated CFR/ PEEK (15.7 AE 4.5 MPa) and HA-coated titanium alloy (14.1 AE 6.0 MPa) exhibited significantly larger interfacial shear strengths than the uncoated CFR/PEEK (7.7 AE 1.8 MPa) and the uncoated titanium alloy (7.8 AE 2.1 MPa) at 6 weeks. At 12 weeks, only the uncoated CFR/PEEK (8.3 AE 3.0 MPa) exhibited a significantly smaller interfacial shear strength, as compared to the HA-coated CFR/PEEK (17.4 AE 3.6 MPa), HA-coated titanium alloy (14.2 AE 4.8 MPa), and uncoated titanium alloy (15.0 AE 2.6 MPa). Surface analysis of the removed implants revealed detachment of the HA layer in both the HA-coated CFR/PEEK and titanium alloy implants Keywords: carbon-fiber-reinforced PEEK; interfacial shear strength; hydroxyapatite; coating adhesion; osseointegration Carbon-fiber-reinforced polyetheretherketone (CFR/ PEEK) is attractive for use in orthopedic implants, 1-4 due to high fatigue strength, high chemical stability, no metal ion release, and excellent biocompatibility with direct cell attachment. 5,6 Moreover, mechanical properties, including strength, toughness, and stiffness, can be easily modified by the arrangement of reinforcing fiber volume and orientation. In cementless hip prostheses, tailoring stiffness can minimize bone resorption of the proximal femur due to stress shielding by designing CFR/PEEK stems with elasticity similar to surrounding cortical bone. 7-10 The fatigue resistance and toughness could minimize the risk of implant fracture. 11-13 The metal-free nature of CFR/PEEK prostheses eliminate metal allergy concerns 14 and problems passing through security gates with metal detectors. 15 Furthermore, CT and MRI of areas around the implants can be achieved without artifacts. 16 Despite these theoretical advantages, CFR/PEEK cementless hip prostheses are not yet practical for clinical applications. In vivo wear resistance and subsequent immunoreaction have not been established when used as a bearing surface. Another issue is implant fixation. Achieving a stable bone-implant interface by osseointegration has been a longstanding problem with carbon-fiber-reinforced polymer materials, including CFR/PEEK. 17,18 To date, studies have focused on wear reduction 4,19 or secure implant fixation 20-27 to develop cementless CFR/PEEK prostheses.Given that CFR/PEEK is...

Poly(ether-ether-ketone) (PEEK)s are a group of polymeric biomaterials with excellent mechanical properties, chemical stability, and nonmagnetism. In the present study, we propose a novel self-initiated surface graft polymerization technique, using which we demonstrate the fabrication of a highly hydrophilic and biocompatible nanometer-scale layer on the surfaces of PEEK and carbon fiber-reinforced PEEK (CFR-PEEK) by the photoinduced graft polymerization of 2-methacryloyloxyethyl phosphorylcholine (MPC) without using any photoinitiators. The thus formed hydrophilic and smooth 100-nm-thick PMPC-grafted layer caused a significant reduction in the sliding friction of the bearing interface because the thin water film and hydrated PMPC layer acted as extremely efficient lubricants (so-called fluid-film lubrication or hydration lubrication). Fluid-film lubrication suppressed the direct contact of the counterbearing surface with the PEEK substrate and thus reduced the frictional force. A PMPC-grafted layer is therefore expected to significantly increase bearing durability. Furthermore, the PMPC-grafted layer shows unique phenomena, e.g., it prevents damage of the metal counter surface regardless of the carbon fiber content of CFR-PEEK. Smart PEEK using the self-initiated surface graft polymerization of MPC should lead to development of novel orthopedic bearings.
