Patient Satisfaction, Functional Outcomes, and Survivorship in Patients with a Customized Posterior-Stabilized Total Knee Replacement.

Background: In this study, we assessed implant survivorship, patient satisfaction, and patient-reported functional outcomes at approximately 2 years for patients who had received a customized posterior-stabilized (PS) knee replacement system. We hypothesized that the customized PS implant would have high overall patient-reported outcomes because of its patient-specific design.

Methods: Ninety-three patients (100 knees) who had received the customized total knee replacement system were enrolled at 2 centers.

A 3 km spatially and temporally consistent European daily soil moisture reanalysis from 2000 to 2015.

High-resolution soil moisture (SM) information is essential to many regional applications in hydrological and climate sciences. Many global estimates of surface SM are provided by satellite sensors, but at coarse spatial resolutions (lower than 25 km), which are not suitable for regional hydrologic and agriculture applications. Here we present a 16 years (2000-2015) high-resolution spatially and temporally consistent surface soil moisture reanalysis (ESSMRA) dataset (3 km, daily) over Europe from a land surface data assimilation system.

Intravenous Iron May Improve Outcomes in Elderly Patients With Operative Hip Fractures.

Introduction: Hip fractures are common injuries with high morbidity and mortality rates. These patients often become anemic and require allogenic blood transfusion. Transfusions are costly with potential complications.

The Social and Functional Implications of High- Versus Low-Dose Opioids on Chronic Non-Cancer Pain.

Background: Chronic non-cancer pain (CNCP) is a major health concern. Opioids may be a useful treatment option, but their use still remains controversial given the significant risks and epidemic of opioid addiction and abuse. There is limited data on whether opioid therapy is an effective treatment option for chronic non-cancer pain.

What Is the Possible Impact of High Variability of Distal Femoral Geometry on TKA? A CT Data Analysis of 24,042 Knees.

Background: Previous studies analyzing femoral components of TKAs have demonstrated the limited ability of these components to accommodate size variations seen in the patient population, particularly width and femoral offset.

Questions/purposes: The purpose of this study was to use a large data set of knee CT scans (1) to determine the variations in the distal and posterior femoral geometries and to determine whether there is a correlation between distal condylar offset and posterior femoral offset as a potential parameter for symmetry/asymmetry; and (2) to evaluate what proportion of knees would have a substantial mismatch between the implant's size or shape and the patient's anatomy if a femoral component of a modern standard TKA of symmetric (sTKA) or asymmetric (asTKA) designs were to be used.

Methods: A retrospective study was performed on 24,042 data sets that were generated during the design phase for a customized TKA implant.
