We developed an open-sourced program that accounts for the current limitations of B-mode ultrasound and extends the clinical utility of ultrasound for assessing femoral trochlear cartilage thickness. Images were collected on 18 patients with a history of knee surgery. By failing to account for ultrasound acoustics and beam refraction, cartilage thickness was underestimated by 26% and overestimated by 0-4%, respectively ( < 0.001). Comprehensive thickness measurements achieved by measuring the Euclidean distance between every point were significantly different than traditional single-location measurements or by using the area/length ( = 0.004-0.006). Sub-regions were significantly different than all whole regions of interest ( = 0.001-0.012).

Tumor necrosis factor-α (TNF-α) induces a multitude of actions and consequences in bone and cartilage resorption and immune response augmentation. In this research, we aimed to investigate the effects of TNF-α on osteogenesis parameters in newborn mice. Experimental research was conducted on 42 pregnant mice, dividing into seven groups as follows: control (no injection), vehicle 1 (PBS injection on 7-9th pregnancy days (PD)), vehicle 2 (PBS injection during pregnancy), experimental 1 (injection of 10 ng/kg of TNF-α on 7-9th PD), experimental 2 (injection of 100 ng/kg of TNF-α on 7-9th PD), experimental 3 (injection of 10 ng/kg of TNF-α during pregnancy) and experimental 4 (injection of 100 ng/kg of TNF-α during pregnancy).

Objective: The aim of this study was to evaluate disc metabolism after decreasing the axial load through surgery by assessing the glycosaminoglycan content through a non-invasive method-delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC).
Methods: Sixteen patients with mono-segmental disc degeneration (L4-L5 or L5-S1) who underwent posterior lumbar spine fixation with intervertebral distraction of 2 consecutive vertebrae using monoaxial transpedicular screws and lyophilized allograft to achieve segmental fusion, and who had a follow-up period of at least 2 years, were included in this study. The first lumbar disc was used as the control group.

Background Deep learning (DL) methods can improve accelerated MRI but require validation against an independent reference standard to ensure robustness and accuracy. Purpose To validate the diagnostic performance of twofold-simultaneous-multislice (SMSx2) twofold-parallel-imaging (PIx2)-accelerated DL superresolution MRI in the knee against conventional SMSx2-PIx2-accelerated MRI using arthroscopy as the reference standard. Materials and Methods Adults with painful knee conditions were prospectively enrolled from December 2021 to October 2022.

From the Department of Plastic and Reconstructive Surgery, Beaumont Hospital, Dublin, Ireland.
Background: The use of PolyNovo NovoSorb biodegradable temporizing matrix (BTM) has become popular for the management of complex wounds, often with the subsequent application of a split-thickness skin graft. To date, there are no published case series describing healing via secondary intention over BTM in the management of small, complex nasal wounds following excision of skin malignancy in the elective setting.
Methods: This study consisted of a single-center, consecutive case series.
