The impact of elective total hip and knee arthroplasty on physical performance in orthogeriatric patients: a prospective intervention study

BMC Geriatrics, 2023
Background Osteoarthritis is a prevalent condition in older adults that leads to reduced physical function in many patients and ultimately requires hip or knee replacement.

Does choice of bearings influence the survival of cementless total hip arthroplasty in patients aged 20–55 years? Comparison of 21,594 patients reported to the Nordic Arthroplasty Register Association dataset 2005–2017

Acta Orthopaedica, 2023
Background and purpose: The bearings with the best survivorship for young patients with total hip arthroplasty (THA) should be identified. We compared hazard ratios (HR) of revision of primary stemmed cementless THAs with metal-on-metal (MoM), ceramic ...

Failure characteristics of all polyethylene cemented glenoid implants in total shoulder arthroplasty [PDF]

, 2010
Total shoulder arthroplasty (TSA) still suffers today from mid-term and long-term complications such as glenoid implant loosening, wear, humeral head subluxation/dislocation and implant fracture. Unlike the hip and knee joint replacements, the artificial

The Synergy of Artificial Intelligence and 3D Bioprinting: Unlocking New Frontiers in Precision and Tissue Fabrication

Advanced Functional Materials, EarlyView.
Advances in integrating artificial intelligence into 3D bioprinting are systematically reviewed here. Machine learning, computer vision, robotics, natural language processing, and expert systems are examined for their roles in optimizing bioprinting parameters, real‐time monitoring, quality control, and predictive maintenance.

Primary hip and knee arthroplasty at district level is safe and may reduce the burden on tertiary care in a low-income setting

BMC Musculoskeletal Disorders, 2022
Background Arthroplasty procedures in low-income countries are mostly performed at tertiary centers, with waiting lists exceeding 12 to 24 months. Recently, this is further exacerbated by the impact of the Covid Pandemic on elective surgeries.

Multiscale Hybrid Surface Topographies Orchestrate Immune Regulation, Antibacterial Defense, and Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Hybrid wrinkled topographies coordinate immune, tissue, and bacterial interactions. The surfaces promote osteointegration, tune macrophage polarization, and inhibit biofilm formation, highlighting a multifunctional strategy for next‐generation implant design.

Adverse Local Tissue Reaction Secondary to Corrosion at Multiple Junctions in a Modular, Segmental, Distal Femoral Replacement

Arthroplasty Today, 2023
While adverse local tissue reactions are well described in the total hip arthroplasty literature, there have only been case reports and case series in the total knee arthroplasty literature.

Total Ankle Replacement Arthroplasty

Journal of Korean Foot and Ankle Society, 2015
Total ankle replacement has been performed for treatment of end stage arthritis of the ankle, hopefully being an alternative to ankle arthrodesis. However, due to its high failure rates, earlier versions of ankle replacements were not regarded as successful procedures.

Autonomous Implants

Advanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Disruption of Sulfur Metabolism and Redox Homeostasis in Staphylococcus aureus Using Mechanically Robust Antibiofilm Ti‐Bi Alloys

Advanced Materials Interfaces, EarlyView.
Titanium (Ti) and bismuth (Bi) are selected as alloying elements for the preparation of the Ti‐Bi binary alloy system. Biofilm formation is found to be inhibited by bismuth through the disruption of sulfur metabolism and redox homeostasis, as well as through the direct downregulation of biofilm‐associated proteins.
