“…It applies to confined spaces or crevices in an implant, which may not be in direct access to fluid from the surrounding environment . There is a deficient diffusion of ions to and from the immediate surrounding region of the implant, thereby producing a harsher corrosive environment . Compared with pitting corrosion, as the crevice environment becomes more corrosive, the activation energy is lowered, producing more acidic conditions, which increases the reaction energy for corrosion .…”

“…Mechanical assisted crevice corrosion (MACC) is a form of corrosion where a crevice was facilitated by mechanical stress/mechanical motion. , Modular taper interfaces of MOM have been suggested to have a risk of MACC, owing to the tribocorrosion process occurring at the femoral trunnion; the neck-stem junction, the acetabular liner shell junction, and other metallic modular connections have been reported as the root cause Figure .…”

“…The secretions from these inflammatory cells usually cause the granulation of tissues, and subsequent formation of fibrous capsules, compromising collagen matrixes, fibrocytes, and fibroblasts. , Polymorphonuclear leukocytes (e.g., neutrophils, eosinophils, and basophils) may infiltrate the corrosion sites, followed by more monocytes and macrophages. The fibroblasts and endothelial cells around the implants add to the formation of fibrous capsules, with an end reaction being the formation of an irreversible thick fibrous capsule around the implant. , Other times, the chronic inflammation from these responses to corrosion byproducts leads to the pathology of metallosis and adverse local tissue reaction (ALTR) to metal debris, Figure , with their characteristic discoloration of surrounding tissues. ,, …”

Arthroplasty implants can undergo corrosion at the modular components, trunnion, and hinges, owing to implant material makeup, micromotion, and interaction with body fluid. In this review, various mechanisms of corrosion in arthroplasty were explored with suggestions on means of improvement. We identified 10 methods including pitting, crevice, mechanically assisted crevice corrosion, fretting, fretting initiated crevice corrosion, mechanically assisted taper corrosion, galvanic corrosion, stress/ tension, fatigue corrosion, and inflammatory cell induced corrosion. The position of implants on the galvanic series, and their ability to maintain passivation contribute to their longevity in service. Due to the relative motion of arthroplastic components, bio-tribocorrosion may disrupt passive oxide films, and pitting is initiated at interfaces. Thus, corrosion in arthroplasty as an electrochemical phenomenon mainly starts on one spot and progresses in 3 steps: (1) the oxidative dissolution of metal from implant surfaces into the aqueous active environment, releasing cations, (2) the attraction of electrons to the opposite charge created at another point of the implant surface, producing current flow, and (3) the formation of oxides of metal and metal hydroxides deposited as rust at the surface of the implant. Recent innovations in material manufacturing continue to improve the efficiency of arthroplasty; however, the component parts remain susceptible to biotribocorrosion. Thus, a complete eradication of corrosion in arthroplasty would require futuristic materials with improvement in recent materials and designs, derived from knowledge of existing retrieved implants, and strategies to provide overall surface finishes that protect against bio-tribocorrosion.

“…In this interesting series from Portland (Maine, USA) , the authors reviewed a consecutive series of 162 patients all of whom had cementless THA from a single manufacturer using a titanium stem, CoCr head, and cross-linked polyethylene (XLPE) liner. 3 Although 53 patients were lost to follow-up, died, or underwent an unrelated early revision, the remaining two-thirds of patients all had metal ion levels drawn at their ten-year follow-up appointment. Of these subjects, 35 patients (32%) had cobalt levels ≥ 1 ppb, which is a finding consistent with mechanically assisted crevice corrosion (MACC).…”

“…Mechanically assisted crevice corrosion (MACC) at the trunnion-bore junction of a metal-on-polyethylene (MoP) total hip arthroplasty (THA) is recognized as a cause of adverse local tissue reactions (ALTRs) including inflammatory reactions and tissue necrosis [ [1] , [2] , [3] , [4] ]. A revision surgery to remove the cobalt (Co) alloy femoral head is effective at removing ion generation [ 5 , 6 ], but early complication rates have been reported in over 25% of surgeries, most commonly dislocation (22%) and early deep infection (11%) [ 7 ].…”
