Decreased Association Between Patellar Axial Malalignment and Patellar Height and Increased Association Between Patellar Axial Malalignment and Tibial Tubercle-Trochlear Groove During Weightbearing.
Clin Orthop Relat Res
January 2025
Department of Radiology, Chongqing Health Center for Women and Children/Women and Children's Hospital of Chongqing Medical University, Chongqing, PR China.
Background: Nonweightbearing preoperative assessments avoid quadriceps contraction that tends to affect patellar motion and appear to be inaccurate in quantifying anatomic factors, which can lead to incorrect corrections and postoperative complications.
Questions/purposes: (1) Does the relationship of patellar axial malalignment and other anatomic factors change during weightbearing? (2) What anatomic factor was most strongly correlated with recurrent patellar dislocation during weightbearing?
Methods: This prospective, comparative, observational study recruited participants at our institution between January 2023 and September 2023. During this time, all patients with recurrent patellar dislocations received both weightbearing and nonweightbearing CT scans; control patients who received unilateral CT scans because of injuries or benign tumors received both weightbearing and nonweightbearing CT scans.
Is Area-Level Social Vulnerability Index Associated With Patient-Level Health-Related Social Needs in Hand Surgery?
J Am Acad Orthop Surg
January 2025
From the Department of Orthopaedic Surgery, Stanford University, Stanford, CA (Schultz), Department of Orthopaedic Surgery, University of Pennsylvania, Philadelphia, PA (Zhuang), Department of Orthopaedic Surgery, University of California-San Francisco, San Francisco, CA (Shapiro), Department of Orthopaedic Surgery, VOICES Health Policy Research Center, Stanford University, Stanford, CA (Kamal).
Background: Social drivers of health (SDOH) are area-level, nonmedical factors that affect health outcomes. By contrast, health-related social needs (HRSNs) are individual patient reported and are being deployed in some payment models. SDOH are often used to broadly represent health disparities of communities through metrics, such as the Social Vulnerability Index (SVI); however, the association of area-level SVI to individual HRSNs has not been well studied in hand surgery, which has implications for addressing social risks to improve health and in quality measurement.

J Cardiovasc Med (Hagerstown)
February 2025
Cardiology Unit, Azienda Ospedaliera Universitaria di Ferrara, Cona, Ferrara, Italy.
Introduction: Cardiac amyloidosis typically causes restrictive cardiomyopathy, in which the impairment of diastolic function is dominant. Echocardiography provides prognostic information through some important parameters: left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS). However, LVEF often remains preserved despite disease progression, and GLS is not routinely performed as it is limited by suboptimal image quality.

J Bone Joint Surg Am
January 2025
Department of Orthopaedic Oncology, Learning Cancer Outcome Research Program, The University of Texas MD Anderson Cancer Center, Houston, Texas.
Background: Comorbidity indices are used to help to estimate patients' length of hospital stay, care costs, outcomes, and mortality. Increasingly, they are considered in reimbursement models. The applicability of comorbidity indices to patients undergoing orthopaedic oncology surgery has not been studied.

Arq Bras Cir Dig
January 2025
Universidade de São Paulo, Faculty of Medicine - São Paulo (SP), Brazil.
Background: Pancreatic neuroendocrine tumors (PNETs) are uncommon and heterogeneous neoplasms, often exhibiting indolent biological behavior. Their incidence is rising, largely due to the widespread use of high-resolution imaging techniques, particularly influencing the diagnosis of sporadic non-functioning tumors, which account for up to 80% of cases. While surgical resection remains the only curative option, the impact of factors such as tumor grade, size, and type on prognosis and recurrence is still unclear.
