“…The L–S model caused high stress in host cancellous bone. High stress levels, particularly acting on weak cancellous bone, have been implicated as the predominant cause of tibial component loosening [ 23 , 24 ], and the abnormal stress pattern may cause stress shielding in long-term follow-up [ 25 , 26 ]. The stress pattern produced by load sharing between the implant and bone suggests that large soft bone grafting should be avoided in favor of grafting with hard bone to eliminate excessive stress in host cancellous bone.…”

BackgroundAchieving stability of the tibial implant is essential following cementless total knee arthroplasty with bone grafting. We investigated the effects of bone grafting on the relative micromotion of the tibial implant and stress between the tibial implant and adjacent bone in the immediate postoperative period.MethodsTibial implant models were developed using a nonlinear, three-dimensional, finite element method. On the basis of a preprepared template, several bone graft models of varying sizes and material properties were prepared.ResultsMicromotion was larger in the bone graft models than in the intact model. Maximum micromotion and excessive stress in the area adjacent to the bone graft were observed for the soft and large graft models. With hard bone grafting, increased load transfer and decreased micromotion were observed.ConclusionsAvoidance of large soft bone grafts and use of hard bone grafting effectively reduced micromotion and undue stress in the adjacent area.

“…Fretting wear also occurs in other fields of technology, where a pair of elements touching each other is subjected to oscillatory tangential displacement. It follows from the review of literature that fretting wear is found in, for example, aviation industry [5][6][7], in medicine [8][9][10] in orthopaedic items connecting fractured limbs and in artificial joints, as well as in the automotive industry [11].…”

Fretting Wear in Selected Elements of Rail Vehicles

The wear of vehicle elements during operation is a natural phenomenon. A dangerous situation occurs when elements more crucial than others wear unexpectedly. Such an element in rail vehicles is, for example, a wheel set. Its main task is to run the vehicle in the track, which directly influences the safety of the journey. Any premature or unexpected damage will lead to train derailing. Then hundreds of lives may be lost. The load on the wheel set from the vehicle weight and the oscillatory micro displacement of the wheel in relation to its axle during travel will be conducive to premature wear. Those conditions will cause the development of fretting wear, whose implication may be fatigue wear or the loosening of the wheel/axle joint. In this article, the results of fretting wear tests conducted in a shaft/sleeve forced-in joint are presented. The results of those tests, given that the relevant probability conditions are met, can be successfully compared to the real wheel/axle joint. The wheel set operation conditions, which will be conducive to the initiation of the development of fretting wear, have been discussed. Test results are presented in the photographs showing the axle seat with an area affected by wear. Both those places, and the place of contact between the connected surfaces, were subjected to micrographic examinations with a view to identifying damage comprised by fretting. Macrographic observations demonstrated fretting on either side of the shaft axle seat, which phenomenon comprises, for example, abrasive wear and adhesion. Visible are micro cracks and material build-ups, which became plastically deformed and oxidised.

“…Metal debris generated at this junction is thought to be due to fretting corrosion at the metal on metal interface [10] . Corrosion and subsequent micro motion at the trunnion deposits metal debris within local soft tissues [2,8] . This process has been shown to cause an adverse reaction to metal debris (ARMD) and is associated with increased prosthetic failures [9,11 -13] .…”

Modularity of prosthetic implants is increasingly being utilized for the optimization and personalization of components in total hip and knee arthroplasty. However, due to the increasing number of modular implants being utilized, an adverse event termed trunnionosis has gained prevalence. Trunnionosis is defined as corrosion and wear of the taper junction in modular prostheses. It is postulated that this corrosive wear generates metal debris, which leads to component failure and requires revision of the prosthetic implant. The process of trunnionosis has been extensively studied in total hip arthroplasty. However, few studies have examined the process of trunnionosis in total knee arthroplasty. The aim of this review is to examine the literature regarding trunnionosis following total knee arthroplasty. Specifically, we aim to determine if trunnionosis following total knee arthroplasty is a rare clinical problem, or one that deserves greater attention.
