3D‐Printed Titanium Gyroid Scaffold Structure Integrated With Tough Hybrid Materials for Cartilage Replacement

Advanced Engineering Materials, EarlyView.
This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

Revision hip arthroplasty

N.N. Priorov Journal of Traumatology and Orthopedics, 2022
From 1990 to 2000 238 revision hip joint replacements were performed at Joint Replacement Department of CITO. Both cement and cementless implants as well as in case of need allografts in the form of bone chips and spongeous bone were used. Technique peculiarities of revision operations for Sivash and Compomed implants replacement are described.

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

Fast fix or false hope? Polyethylene exchange in unstable primary unconstrained total knee arthroplasty

Bone & Joint Open
Aims: Instability is a leading cause of revision after primary total knee arthroplasty (TKA). Isolated polyethylene exchange (IPE), typically involving increased insert thickness, is considered a fast and low-risk treatment option.

Stem retention and survival in revision of anatomical convertible shoulder arthroplasty to reverse arthroplasty: a Dutch registry study

BMC Musculoskeletal Disorders, 2021
Background Convertible stem designs allow for stem retention during revision from anatomical to reverse shoulder arthroplasty. In some cases conversion is not possible for example due to excessive soft tissue tensioning.

Total Hip Arthroplasty in Patients With Parkinson Disease: Improved Outcomes With Dual Mobility Implants and Cementless Fixation [PDF]

, 2017
Background: Parkinson disease (PD) results in severe limitation in ambulation caused by abnormality of gait and posture. The rate of complications, including fractures and dislocation after total hip arthroplasty (THA), can be higher among these ...

Ultrasound‐Activatable Piezoelectric Hydrogel Reprograms Mitochondrial Epigenetics for Osteoarthritis Therapy via the mTOR/GATD3A Axis

Advanced Science, EarlyView.
An ultrasound‐activatable piezoelectric hydrogel reprograms chondrocyte mitochondrial epigenetics via the mTOR/GATD3A axis, clearing damaged mitochondria and alleviating osteoarthritis progression in both mouse models and human cartilage explants. ABSTRACT The avascular nature of cartilage hinders drug delivery for osteoarthritis (OA) therapy.

Revision of metal-on-metal hip replacements with dual-mobility bearings and acetabular component retention

Bone & Joint Open
Aims: In metal-on-metal (MoM) hip arthroplasties and resurfacings, mechanically induced corrosion can lead to elevated serum metal ions, a local inflammatory response, and formation of pseudotumours, ultimately requiring revision. The size and diametral

Occlusion of an Aortobifemoral Graft after Revision Total Hip Arthroplasty

Arthroplasty Today, 2021
With the aging population, the demand for total hip arthroplasty is rising. Improvements in arthroplasty techniques and design allow for total hip arthroplasty to be increasingly performed in older patients and those with multiple comorbidities ...
