Lateral meniscus injuries have more impact on pivot shift than anterolateral complex injuries in anterior cruciate ligament‐injured knees

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this prospective study was to investigate the effect of Kaplan fibres (KF), anterolateral ligament (ALL) and lateral meniscus (LM) injuries on preoperative anterolateral rotational instability (ALRI) in anterior cruciate ligament (ACL)‐injured knees.

Visual inspection provides precise intraoperative evaluation of tibial slope during unicompartmental knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Accurate reconstruction of the posterior tibial slope (PTS) is essential for successful unicompartmental knee arthroplasty (UKA), yet intraoperative assessment remains challenging without advanced navigation tools. This study evaluated the accuracy of visual intraoperative assessment of PTS changes after tibial resection.

A Composite Network for CS ISAR Integrating Deep Adaptive Sampling and Imaging

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Compressive sensing (CS) actively contributes to inverse synthetic aperture radar (ISAR) imaging with less raw data. The design of the measurement matrix and the development of reconstruction methods are critical processes in CS ISAR imaging.

Minced cartilage implantation provides comparable outcomes to autologous chondrocyte implantation (ACI) for knee cartilage lesions: A matched‐pair analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare short‐term patient‐reported outcomes (PROMs) and revision rates between autologous hand‐minced cartilage implantation (MCI) and autologous chondrocyte implantation (ACI) for knee cartilage lesions. Methods All patients undergoing MCI or ACI at a single centre were retrospectively analysed from a prospectively maintained ...

Performance Analysis on ISAR Imaging of Space Targets

Leida xuebao, 2017
Usually, in traditional Inverse Synthetic Aperture Radar (ISAR) systems design and mode selection for space satellite targets, coherent integration gain in azimuth direction hardly can be analyzed, which depends on target’s motion.

Managing the meniscus part I—Anatomy, biomechanics, and treatment strategies for the atraumatic meniscus tear

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this article is to serve as the first of a two‐part review on the meniscus; in this review, we will establish the background on anatomy and pathogenesis of the meniscus, as well as the effect of the meniscus on native knee kinematics and function.
