Background: Arthroplasty registries play a critical role in improving the quality of care and performing post-market surveillance of medical devices. We report the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) findings specific to the Biomet Vanguard XP bicruciate-retaining total knee implant.

Methods: Data were collected from MARCQI's 2019 report (February 15, 2012, through December 31, 2018).

Aims: The efficacy of saline irrigation for treatment of implant-associated infections is limited in the presence of porous metallic implants. This study evaluated the therapeutic efficacy of antibiotic doped bioceramic (vancomycin/tobramycin-doped polyvinyl alcohol composite (PVA-VAN/TOB-P)) after saline wash in a mouse infection model implanted with titanium cylinders.

Methods: Air pouches created in female BalBc mice by subcutaneous injection of air.

The 2024 Mary Tyler Moore Vision Initiative (MTM Vision) Workshop on Data convened to discuss best practices and specific considerations for building a comprehensive, shareable MTM Vision data lake. The workshop aimed to accelerate the development of new indications, therapies, and regulatory pathways for diabetic retinal disease (DRD) by standardizing and harmonizing clinical data and ocular 'omics analyses. Standardization of data collection, the use of common data elements, and data interoperability were emphasized, alongside federated learning approaches to promote data sharing and collaboration while maintaining data privacy and security.

Cellular infiltration into electrospun nanofibers (NFs) is limited due to the dense structure and small pore sizes. We developed a programmed NF collector that can fabricate porous NFs with desired pore sizes and thickness. Previously we demonstrated improved cellular proliferation and differentiation of osteoblasts, osteoclasts, and fibroblasts with increased pore sizes of polycaprolactone (PCL) NF in-vitro.

Background: There is a desire in orthopaedics to have soft tissue, particularly tendon, grow into metallic implants. With the introduction of three-dimensional (3D) printed porous metal implants, we hypothesized that tendons could directly attach to the implants. However, the effects of the porous metal structure on tissue growth and penetration into the pores are unknown.
