Taguchi Optimization of Additively Manufactured <span>PEKK</span> and Silicon Nitride Loaded <span>PEKK</span> for Medical Device Applications Open
Silicon nitride (Si 3 N 4 ) is reported to exhibit antibacterial properties and support osteoblast maturation, while polyetherketoneketone (PEKK) is considered to potentially have antibacterial and osseointegrative properties while offerin…

Hinge-Knee Megaprostheses Components Wear and Corrode: A Retrospective Study of 40 Devices Open
Introduction: Hinge-knee megaprostheses are frequently used in complex revision surgeries and are known to have higher complication and revision rates than primary total knee arthroplasties. However, the in vivo damage to the metal and pol…

Rim Damage in Retrieved 1st and 2nd Generation Annealed Highly Crosslinked Polyethylene Hip Liners Open
We analyzed the rim damage modes of retrieved 1st and 2nd generation-annealed HXLPE THA liners. We observed that the sequentially annealed liners had lower levels of damage as compared to annealed HXLPE liners. The clinical relevance of th…

Oxidation and Damage Mechanisms of Second-Generation Highly Cross-Linked Polyethylene Tibial Inserts Open
Revision reasons and surface damage mechanisms were comparable in the Gamma Inert and SA cohorts. Further studies are needed to continue to assess the in vivo damage and clinical relevance, if any, of oxidation in SA HXLPE over longer impl…

Femoral Head Penetration Rates and Oxidation of Highly Cross-Linked Polyethylene Hip Liners Implanted More Than 10 Years Open
Oxidation was found to be higher in the annealed HXLPE; however, this does not seem to be associated with greater wear as we found the average penetration rates for the cohorts were low, and the penetration rates were similar between the a…

Exploring the mechanical strength, antimicrobial performance, and bioactivity of 3D-printed silicon nitride-PEEK composites in cervical spinal cages Open
In this study, our goal was to assess the suitability of a polyether-ether-ketone (PEEK) and silicon nitride (Si3N4) polymer composite for antimicrobial three-dimensional (3D)-printed cervical cages. Generic cage designs (PEEK and 15…

Patellar management during total knee arthroplasty: a review Open
The optimal management of the patella during total knee arthroplasty (TKA) remains controversial and surgeons tend to approach the patella with one of three general mindsets: always resurface the patella, never resurface the patella, or se…
