(Inter)national Review of Periprosthetic Hip and Knee Fracture Diagnostic and Treatment Strategies
Periprosthetic fractures (PPF) after total hip arthroplasty (THA) and total knee arthroplasty (TKA) complicate care and hinder benchmarking. We asked: which parameters are essential for an international PPF registry? A two-round Delphi consensus with purposive and snowball sampling recruited 30 …

The adoption of laser melting technology for the manufacture of functionally graded cobalt chrome alloy femoral stems
… good. However, the stress shielding of the periprosthetic femur is a factor that can contribute towards the premature loosening of the femoral stem. In order to improve the stress shielding characteristics of metallic femoral stems, stiffness configurations that offer more flexibility should …

Failure of Primary Total Knee Arthroplasty: Establishing a Baseline for Retrieval Analysis Using Well-Functioning Necropsy Specimens
… would increase metal concentrations in the periprosthetic tissue, that cytokines specifically tied to the innate immune system would be elevated in laxer joints, and, lastly, that elevated inflammatory cytokines in the synovial fluid would be associated with elevated periprosthetic tissue …

Standzeitverkürzende Patientencharakteristika und Protheseneigenschaften von aseptisch gelockerten Hüftendoprothesen
… analyzed with regard to existing osseous periprosthetic bone defects (DeLee - Gruen.-.Zone classification). The shape of the prostheses, the fixation techniques, the materials of the individual components, the number of revisions as well as sex, weight and age of the patients were taken …

In Vivo Wear Performance of Highly-crosslinked Polyethylene in Total Hip Arthroplasty
… However, volumetric wear and the associated periprosthetic tissue response remain one of the key issues in long-term THA outcomes; in fact, recent findings indicate that HXLPE components generate finer wear particles that seem to induce a stronger inflammatory cell response, potentially …

The Fc Orth (SA) final examination The short-term outcome of hip revision arthroplasty with Trabecular Metal™ components and augments
… loosening 11 (9.5%), liner wear 18 (15.5%), periprosthetic fracture five (4.3%), other 15 (13%). Conclusion: In our institution, Trabecular Metal™ revisions had a 18.7% early failure rate due to technical error. 12% of the arthroplasty is revision surgery. The indications for revision are …

Primary Hip And Knee Arthroplasty At District Level Is Safe And May Reduce The Burden On Tertiary Care In A Low-Income Setting
… and tertiary hospitals respectively (p>0.05). Periprosthetic joint infection (PJI) rate was 0.43% at DH and 2.26% at TH. The percentage of hip dislocation requiring revision was 0% at district and 0.37% at tertiary level. During the study period, 228 patients received their arthroplasty surgery …

Aseptic loosening around total hip and knee arthroplasty is linked to plasma microRNA
… These miRNA all had several mRNA targets in the periprosthetic bone and tissue around the prosthesis. The potential pathways by which these regulate bone resorption are the Wnt and JAK-STAT pathways. Protein expression analyses confirm differences in protein expression are detectable at the …

Numerical and experimental studies on the mechanical behaviour of the distal femur following total knee arthroplasty
… with osteoporosis may be at increased risk of periprosthetic fracture compared to younger healthy patients. The use of a revision femoral component with a cemented stem as a means to mitigate this fracture risk was also investigated. FE analyses using frictional interfaces were employed to …

Behandlungsergebnisse bei periprothetischen Femurfrakturen : eine retrospektive Studie
Die Inzidenz periprothetischer Femurfrakturen nimmt kontinuierlich zu und stellt in ihrer Behandlung zum einen auf Grund der hohen technischen Anforderung an den Operateur eine besondere Herausforderung dar. Zum anderen handelt es sich bei diesem Patientengut in den meisten Fällen um Patienten in …

Humeral shaft fractures: epidemiology, outcomes and predictors of nonunion
… pathological fractures 1.1/100,000/year, periprosthetic fractures 0.4/100,000/year). For typical fractures (n=798), peak incidence was bimodal in men and unimodal in older women (Type G distribution). Fractures involving the proximal- (31%) and middle-thirds (48%) were more likely to occur …
