A CONVEX COMPRESSIBILITY-INSPIRED UNSUPERVISED LOSS FUNCTION FOR PHYSICS-DRIVEN DEEP LEARNING RECONSTRUCTION.
Proc IEEE Int Symp Biomed Imaging
May 2024
Electrical and Computer Engineering, University of Minnesota, Minneapolis, Minnesota, USA.
Physics-driven deep learning (PD-DL) methods have gained popularity for improved reconstruction of fast MRI scans. Though supervised learning has been used in early works, there has been a recent interest in unsupervised learning methods for training PD-DL. In this work, we take inspiration from statistical image processing and compressed sensing (CS), and propose a novel convex loss function as an alternative learning strategy.

This study aims to examine the current landscape of subspecialties and other demographic characteristics of the Department Chairs and Program Directors of orthopaedic surgery residency programs across the United States.
Methods: A list of Department Chairs and Program Directors of all 201 ACGME orthopaedic surgery residency programs was generated from the Orthopaedic Residency Information Network (ORIN) website.
Objectives: More than 20% of patients experience chronic lateral ligamentous instability of the ankle (CLLIOTA) following the appropriate management of an ankle sprain. The modified Broström-Gould (MBG) procedure has become the standard treatment for the anatomic repair of symptomatic CLLIOTA.
Methods: This retrospective, single-group study included all patients with CLLIOTA who underwent surgery using the MBG technique in Shahid Kamyab Hospital, Mashhad, Iran, between July 2015 and August 2020.
Evaluating Differences in Baseline Knee Hyperextension and Postoperative Stiffness Between Patients With Tibial Spine Fracture Versus ACL Tear.
Orthop J Sports Med
January 2025
Division of Orthopaedics, Children's Hospital of Philadelphia, Philadelphia, Pennsylvania, USA.
Background: While generalized ligamentous laxity is a risk factor for anterior cruciate ligament (ACL) reconstruction failure, there is a paucity of literature evaluating underlying dynamic risk factors predisposing pediatric and adolescent patients to ACL tears or tibial spine fractures.
Purpose: To (1) evaluate differences in baseline knee hyperextension and postoperative knee stiffness between patients who sustained tibial spine fractures versus ACL tears and (2) determine whether there were other demographic and dynamic injury differences between these patients.
Study Design: Cross-sectional study; Level of evidence, 3.
Long-term Outcomes After Anterior Cruciate Ligament Reconstruction With 3 Different Surgical Techniques: A Prospective Randomized Clinical and Radiographic Evaluation at a Minimum of 20 Years' Follow-up.
Orthop J Sports Med
January 2025
Clinica Ortopedica e Traumatologica II, Istituto Ortopedico Rizzoli, Bologna, Italy.
Background: In recent years, lateral extra-articular tenodesis (LET) has been shown to be promising in reducing the graft failure rate at short-term follow-up. However, there is a lack of studies investigating the incidence of complications and lateral osteoarthritis (OA) after this procedure, and only a few studies have reported long-term results after anterior cruciate ligament (ACL) reconstruction.
Purpose/hypothesis: This study aimed to compare the failure rate, clinical outcomes, and OA incidence of 3 different ACL reconstruction techniques: single-bundle quadrupled hamstring tendon (HT), bone-patellar tendon-bone (BPTB), and over-the-top HT plus LET (HT + LET).
