Biological Response of Osteoblasts and Osteoprogenitors to Orthopaedic Wear Debris
Total joint replacements are one of the most commonly performed orthopaedic procedures worldwide, with over 700,000 surgeries performed annually in the US to treat arthritic conditions of the hip and knee. One of the major complications of total joint replacement is implant wear and osteolysis, a process that involves continuous shedding of micronand submicron-sized particles from implant compo...
متن کاملWidespread dissemination of metal debris from implants.
In a post-mortem study, we compared subjects with metal implants with and without visible wear with an age-matched control group to determine the extent and effects of dissemination of wear debris. In subjects with stainless-steel and cobalt-chrome prostheses metal was found in local and distant lymph nodes, bone marrow, liver and spleen. The levels were highest in subjects with loose, worn joi...
متن کاملCellular Responses to Orthopaedic Wear Debris Are Influenced by Particle Morphology
Introduction Total joint arthroplasty (TJA) is commonly used to alleviate the debilitating effects of arthritis. Nevertheless, up to 25% of TJA cases will require surgical revision due to implant failure. The generation of wear debris through articulation of the artificial joint is considered one of the prime factors promoting the chronic inflammation that leads to implant failure. Previous stu...
متن کاملAcute inflammatory response to cobalt chromium orthopaedic wear debris in a rodent air-pouch model.
This study used a rodent air-pouch model to assess the acute inflammatory response to cobalt-chromium (CoCr) alloy wear debris from a metal-on-metal hip resurfacing implant that may contribute to joint failure. Air-pouches were injected with either sterile phosphate-buffered saline, 1 μg lipopolysaccharide (LPS) or 2.5 mg CoCr wear debris. The in situ inflammatory response was monitored 4, 24, ...
متن کاملEffects of surface coating on reducing friction and wear of orthopaedic implants
Coatings such as diamond-like carbon (DLC) and titanium nitride (TiN) are employed in joint implants due to their excellent tribological properties. Recently, graphite-like carbon (GLC) and tantalum (Ta) have been proven to have good potential as coating as they possess mechanical properties similar to bones-high hardness and high flexibility. The purpose of this systematic literature review is...
