Erdheim-Chester disease (ECD) is an exceedingly rare non-Langerhans cell CD68 CD1a S100 histiocytic multi-organ disease. Diagnosis of ECD is often delayed due to non-specific radiographic findings and heterogeneous lesional tissue. Increasingly, the role of genomic alterations is being recognized for both diagnosis and treatment of ECD.

As patients typically demonstrate a nonlinear recovery trajectory, advanced analysis investigating the degrees of variation in outcomes is needed. Latent class analysis (LCA) is a mixed and multilevel model that estimates random slope variance to evaluate heterogeneity in outcome patterns among patient subgroups and can be used to outline differing recovery trajectories.
View Article and Find Full Text PDFBackground: Patellar tendon injuries not amenable to primary repair present a challenging problem for surgeons and patients alike. No standard surgical technique exists for these injuries and few studies report outcomes after surgical treatment.
Methods: A retrospective analysis was conducted for patients undergoing surgical treatment for irreparable patellar tendon tears.
Purpose: To describe the diagnosis and 2-year outcomes of arthroscopic treatment for labral calcification in the setting of femoroacetabular impingement syndrome (FAIS).
Methods: A retrospective analysis was performed from a prospectively collected database of patients with FAIS undergoing hip arthroscopy. Patients with FAIS with labral calcification were differentiated radiographically from patients with other paralabral radiopaque densities such as os acetabuli, acetabular rim fractures, and labral ossification.
Background: Disparities associated with socioeconomic status (SES) and insurance coverage have been shown to affect outcomes in different medical conditions and surgical procedures. We hypothesized that patients insured by Medicaid will be associated with lower follow-up rates and inferior outcomes relative to those with Medicare or private insurance.
Methods: Patients undergoing shoulder arthroplasty, including anatomic total shoulder arthroplasty, reverse arthroplasty, and hemiarthroplasty, were enrolled preoperatively in an institutional database.
