Deep collaborative network with alpha matte for precise knee tissue segmentation from MRI.

Comput Methods Programs Biomed 2022 Jun 17;222:106963. Epub 2022 Jun 17.

Department of Imaging and Interventional Radiology, CU lab of AI in radiology (CLAIR), Chinese University of Hong Kong, Prince of Wales Hospital, Shatin N.T., Hong Kong, China. Electronic address:

Background And Objective: Precise segmentation of knee tissues from magnetic resonance imaging (MRI) is critical in quantitative imaging and diagnosis. Convolutional neural networks (CNNs), being state of the art, often challenged by the lack of image-specific adaptation, such as low tissue contrasts and structural inhomogeneities, thereby leading to incomplete segmentation results.

Methods: This paper presents a deep learning-based automatic segmentation framework for precise knee tissue segmentation. Read More

Pectolinarigenin acts as a potential anti-osteosarcoma agent via mediating SHP-1/JAK2/STAT3 signaling.

Biomed Pharmacother 2022 Jun 22;153:113323. Epub 2022 Jun 22.

Department of Orthopedics, Shanghai Bone Tumor Institution, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200080, PR China. Electronic address:

Signal transducer and activator of transcription 3 (STAT3) plays essential roles in cancer progression and has been considered as a promising target for cancer therapy. Here, we used a dual luciferase assay to identify that pectolinarigenin inhibited STAT3 transcriptional activity. Further, results showed pectolinarigenin inhibited constitutive and IL6 induced STAT3 signaling, diminished the accumulation of STAT3 in the nucleus, dimerization and blocked STAT3 DNA binding activity.

Personalised pose estimation from single-plane moving fluoroscope images using deep convolutional neural networks.

PLoS One 2022 24;17(6):e0270596. Epub 2022 Jun 24.

Institute for Biomechanics, ETH Zürich, Zürich, Switzerland.

Measuring joint kinematics is a key requirement for a plethora of biomechanical research and applications. While x-ray based systems avoid the soft-tissue artefacts arising in skin-based measurement systems, extracting the object's pose (translation and rotation) from the x-ray images is a time-consuming and expensive task. Based on about 106'000 annotated images of knee implants, collected over the last decade with our moving fluoroscope during activities of daily living, we trained a deep-learning model to automatically estimate the 6D poses for the femoral and tibial implant components.

A Rabbit Model for Peripheral Nerve Reconstruction Studies Avoiding Automutilation Behavior.

J Brachial Plex Peripher Nerve Inj 2022 Jan 21;17(1):e22-e29. Epub 2022 Jun 21.

Research Center for Nerve Reconstruction, Department of Neurosurgery, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel.

 The rabbit sciatic nerve injury model may represent a valuable alternative for critical gap distance seen in humans but often leads to automutilation. In this study, we modified the complete sciatic nerve injury model for avoiding autophagy.  In 20 adult female New Zealand White rabbits, instead of transecting the complete sciatic nerve, we unilaterally transected the tibial portion and preserved the peroneal portion.

Conversion Total Knee Arthroplasty After Tibial Plateau Fixation Is Associated With Lower Reimbursement, Greater Complication Rates, and Similar Opioid Use.

Cureus 2022 May 20;14(5):e25171. Epub 2022 May 20.

Orthopedics, University of Texas Southwestern Medical Center, Dallas, USA.

Objective Total knee replacement after previous open reduction and internal fixation for tibial plateau fracture (conversion total knee) increases the complexity of the procedure and the complication rate. However, very little research exists to report on opioid use and cost associated with total knee arthroplasty (TKA) following tibial plateau fracture fixation as compared to primary TKA patients with no history of tibial plateau fracture. The aim of this study is to compare the differences in opioid use, reimbursements, and complication rates between patients with and without a history of tibial plateau fracture undergoing TKA.

International Center for Limb Lengthening, Rubin Institute for Advanced Orthopedics, Sinai Hospital of Baltimore, Baltimore, MD 21215, USA.

Concerns surrounding osteolysis near and around the modular junction of a stainless-steel intramedullary lengthening rod prompted a manufacturer recall from the United States market in early 2021. These actions were preceded by similar steps taken in Europe. A concomitant review of stainless-steel lengthenings at our institution demonstrated signs of adverse tissue reaction including periosteal reaction and osteolysis at the modular junction and/or male-sided locking screws.

Exploring Anatomo-Morphometric Characteristics of Infrapatellar, Suprapatellar Fat Pad, and Knee Ligaments in Osteoarthritis Compared to Post-Traumatic Lesions.

Biomedicines 2022 Jun 9;10(6). Epub 2022 Jun 9.

Centre for Mechanics of Biological Materials, University of Padova, 35131 Padova, Italy.

Several studies have investigated cartilage degeneration and inflammatory subchondral bone and synovial membrane changes using magnetic resonance (MR) in osteoarthritis (OA) patients. Conversely, there is a paucity of data exploring the role of knee ligaments, infrapatellar fat pad (IFP), and suprapatellar fat pad (SFP) in knee OA compared to post-traumatic cohorts of patients. Therefore, the aim of this study was to analyze the volumetric and morphometric characteristics of the following joint tissues: IFP (volume, surface, depth, femoral and tibial arch lengths), SFP (volume, surface, oblique, antero-posterior, and cranio-caudal lengths), anterior (ACL) and posterior cruciate ligament (PCL) (volume, surface, and length), and patellar ligament (PL) (volume, surface, arc, depth, and length).
