Predicting Outstanding Results Following Primary Total Hip Arthroplasty Using the Maximal Outcome Improvement Threshold.

Background: The delta difference between baseline patient-reported outcome measure scores and postoperative scores is used to measure success following primary total hip arthroplasty (THA). However, statistical improvement is not necessarily equal to clinical benefit. The percentage of the maximal outcome improvement (MOI) is a psychometric tool to determine clinical improvement.

Editorial Commentary: In Cases of Cam Over-resection and Irreparable Hip Labral Tear Requiring Revision, Acetabular Circumferential Labral Reconstruction With Larger Graft Width Is Indicated.

Hip arthroscopy technique and innovation has revolutionized the surgical approach to femoroacetabular impingement syndrome (FAIS). Arthroscopic labral reconstruction is the gold-standard treatment for irreparable acetabular labral tears in FAIS surgery and backed by robust long-term clinical data. However, cam over-resection has become a prevalent complication, often co-occurring with irreparable labral tears in revision FAIS surgery.

Editorial Commentary: Revision Hip Arthroscopy in Patients With Borderline Dysplasia Has a Role: Indications Are Narrow Versus Periacetabular Osteotomy.

Hip arthroscopy (HA) is preferred for surgical management of femoroacetabular impingement syndrome, whereas periacetabular osteotomy (PAO) is the gold standard for frank developmental hip dysplasia in young adults. Borderline hip dysplasia (BHD) is a conundrum, with data supporting the use of either or both, not to mention that BHD is defined by varying lateral center-edge angle thresholds between 18° and 25° or 20° and 25° and features generalized ligamentous laxity and variations in acetabular and femoral version. That said, HA for BDH has been shown to have 10-year survivorship of 82%.

However, there is a paucity of literature regarding the adolescent population. The purposes of our study were to report on survivorship and patient-reported outcomes (PROs) at a minimum 10-year follow-up in adolescent patients who underwent hip arthroscopy for FAI and labral tears and to compare the survivorship and outcomes of this population with those of a nested, propensity-matched adult control group.

Thermal Compact Modeling and Resistive Switching Analysis in Titanium Oxide-Based Memristors.

Resistive switching devices based on the Au/Ti/TiO/Au stack were developed. In addition to standard electrical characterization by means of - curves, scanning thermal microscopy was employed to localize the hot spots on the top device surface (linked to conductive nanofilaments, CNFs) and perform in-operando tracking of temperature in such spots. In this way, electrical and thermal responses can be simultaneously recorded and related to each other.

Homoleptic complexes of isocyano- and diisocyanobiazulenes with a 12-electron, ligand-based redox capacity.

Oligo- and polyazulenes are attractive π-conjugated building blocks in designing advanced functional materials. Herein, we demonstrate that anchoring one or both isocyanide termini of the redox non-innocent 2,2'-diisocyano-6,6'-biazulenic π-linker (1) to the redox-active [Cr(CO)] moiety provided a convenient intramolecular redox reference for unambiguously establishing that the 6,6'-biazulenic scaffold undergoes a reversible one-step 2 reduction governed by reduction potential compression/inversion.

Holistic Variability Analysis in Resistive Switching Memories Using a Two-Dimensional Variability Coefficient.

We present a new methodology to quantify the variability of resistive switching memories. Instead of statistically analyzing few data points extracted from current versus voltage (-) plots, such as switching voltages or state resistances, we take into account the whole - curve measured in each RS cycle. This means going from a one-dimensional data set to a two-dimensional data set, in which every point of each - curve measured is included in the variability calculation.

Thermal Characterization of Conductive Filaments in Unipolar Resistive Memories.

A methodology to estimate the device temperature in resistive random access memories (RRAMs) is presented. Unipolar devices, which are known to be highly influenced by thermal effects in their resistive switching operation, are employed to develop the technique. A 3D RRAM simulator is used to fit experimental data and obtain the maximum and average temperatures of the conductive filaments (CFs) that are responsible for the switching behavior.

It's not arthritis! Resolution of the illusion of joint space narrowing with acetabuloplasty and labral reconstruction for the calcified labrum.

Labral calcification may be part of the natural history of untreated femoroacetabular impingement syndrome (FAIS) in certain patients, making it a potential target for intervention with the goal of preserving the hip joint. The purpose of this study was to investigate if calcified labra create the appearance of lateral joint space narrowing and report minimum 2-year patient-reported outcome measures (PROMs) after treating patients with arthroscopic acetabuloplasty and labral reconstruction. Prospectively collected data on patients who underwent primary hip arthroscopy for FAIS and labral tearing from February 2015 to April 2021 were reviewed.
