Thick-shell sulcus-deepening trochleoplasty for recurrent patellar dislocation leads to clinically meaningful improvements and high patient satisfaction in adolescents with open physes.

Objectives: To evaluate clinical and radiological outcomes of thick-shell, sulcus-deepening trochleoplasty in patients with open distal femoral physes and less than two years of growth remaining. We hypothesized that patients would have clinical and radiographic improvements in addition to high patient-reported outcomes following thick-shell, sulcus-deepening trochleoplasty.

Methods: Bone age was determined on preoperative magnetic resonance imaging (MRI) using the Pennock Knee Bone Age Atlas.

Dichotomous role of integrin-β5 in lung endothelial cells.

Pulmonary arterial hypertension (PAH) is a progressive, devastating disease, and its main histological manifestation is an occlusive pulmonary arteriopathy. One important functional component of PAH is aberrant endothelial cell (EC) function including apoptosis-resistance, unchecked proliferation, and impaired migration. The mechanisms leading to and maintaining physiologic and aberrant EC function are not fully understood.

The Timing of Preoperative Urinary Tract Infection Influences the Risk of Prosthetic Joint Infection Following Primary Total Hip and Knee Arthroplasty.

Background: The importance of preoperative urinary tract infection (UTI) in total hip and knee arthroplasty (THA and TKA) is controversial. The purpose of this study was to investigate the timing of preoperative UTI diagnosis and association with prosthetic joint infection (PJI) and determine if antibiotics impact this risk.

Methods: A national database was used to analyze patients undergoing THA and TKA diagnosed with a preoperative UTI.
