Corrosion and trib-corrosion behaviour of metallic orthopaedic implant materials
Since the introduction of medical implants into human bodies, corrosion and wear have been regarded as key issues for their long-term durability. There has been a recent renewed interest in the use of large diameter metal-on-metal (MoM) hips, primarily because of the reduced volumetric wear …

Thermal spray of a drug delivery system onto femoral orthopaedic implant
… to apply hydroxyapatite coatings onto metallic implants for use in orthopaedic surgeries. The addition of HA coatings was successful in improving the performance of titanium implants. However, this type of implant has shown some limitations with regards to mechanical (implant loosening) and …

The Effects of Synovial Fluid and Inflammatory Cells on Orthopaedic Implant Alloys
… used to treat end-stage osteoarthritis. The implants used in TKA typically consist of a Cobalt Chromium Molybdenum (CoCrMo) femoral component and a Titanium Aluminum Vanadium (TiAlV) alloy baseplate. These metal alloys are chosen for their mechanical properties, corrosion resistance, high …

IMPLANT MATERIAL FUNCTIONALIZATION TO ENHANCE BIOACTIVITY IN ORTHOPAEDICS
… and regeneration is the engineering of an implant that incorporates osseointegration to meet the metabolic demands of recovery. Although implants are typically expected to last ten years or more, longevity is still not assured and the lack of integration into the bone for long-term survival …

Evaluation of Stress and Fatigue in Femoral Hip Implants
… fatigue life is critical. In order for a femoral implant design to be launched to the market, fatigue testing is required by regulatory bodies as evidence of the implant strength to different potting scenarios. The time required to cut forging dies, finish manufacturing processes, complete …

The influence of nanotopographical structures on osteoblast adhesion formation and the functional response of mesenchymal stem cell populations
… a need for permanent, temporary or biodegradable orthopaedic devices that are designed to substitute or guide bone repair. Polymeric medical devices are widely used in orthopaedic surgery and play a key role in fracture fixation and in areas of orthopaedic implant design. Initial uncertainty …

The Effect of Particle Surface Area to Volume Ratio on Ion Release from CoCr Spheres
… Of these arthroplasties, metal-on-metal type implants represent an increasing usage percentage. Metal-on-metal implants are selected largely for their low volumetric wear rate, durability, and resistance to corrosion. In spite of these advantages, little is known concerning the long-term …
