Limb salvage in multiple revision total knee arthroplasty using customised implants: When sleeves and cones are no longer an option. [PDF]

J Exp Orthop
Abstract Purpose Multiple revision total knee arthroplasty (rTKA) remains highly challenging due to severe bone defects, which often render standard implants unsuitable. This study aimed to evaluate the clinical outcomes, survivorship and complication rates of customised knee implants used in aseptic one‐stage rTKA for patients with severe bone defects.

3D Printing of Bacteriophage‐Loaded Hydrogels: Development of a Local and Long‐Lasting Delivery System

Advanced Healthcare Materials, EarlyView.
This research investigates the feasibility of 3D‐printing of a bacteriophage‐containing hydrogel made of alginate and methylcellulose. The printed hydrogels steadily release active bacteriophages for up to 35 days which is beneficial to treat implant‐associated infections.

Immediate results of treatment periprosthetic femoral fractures after hip replacement

Travmatologiâ i Ortopediâ Rossii, 2016
Periprosthetic fractures are one of the most serious complications after hip replacement. Nineteen periprosthetic femoral fractures operated on during the period 2011-2015 were followed-up retrospectively.

High periprosthetic bone mineral density measured in immediate postoperative period may not guarantee less periprosthetic bone loss in the proximal femur after cementless total hip arthroplasty – A retrospective study

Arthroplasty, 2020
Background Total hip arthroplasty is the most common orthopaedic procedure for the end-stage hip diseases. Periprosthetic bone loss is closely related to the increased risk of implant loosening and periprosthetic fractures, but the predictive value of ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Lattice Structures for Bone Replacement: The Intersection of Bone Biomechanics, Lattice Design, and Additive Manufacturing

Advanced Materials Technologies, EarlyView.
This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...

Development and Validation of Case-Finding Algorithms to Identify Periprosthetic Joint Infections After Total Hip Arthroplasty in Veterans Health Administration Data. [PDF]

Pharmacoepidemiol Drug Saf
ABSTRACT Purpose To determine the positive predictive values (PPVs) of ICD‐9‐ and ICD‐10‐based diagnostic coding algorithms to identify periprosthetic joint infection (PJI) following total hip arthroplasty (THA) within the United States (US) Veterans Health Administration (VHA). Methods We selected patients with: (1) any position hospital discharge ICD‐
