Can low-frequency guided waves at the tibia paired with machine learning differentiate between healthy and osteopenic/osteoporotic subjects? A pilot study.
Ultrasonics
Nov 30, 2018
PURPOSE: Axial transmission quantitative acoustics (ax-QA) has shown to be a promising tool for assessing bone health and properties in a safe, inexpensive, and portable manner. This study investigated the efficacy of low-frequency ax-QA measured at ...
Automated segmentation of knee bone and cartilage combining statistical shape knowledge and convolutional neural networks: Data from the Osteoarthritis Initiative.
Medical image analysis
Nov 17, 2018
We present a method for the automated segmentation of knee bones and cartilage from magnetic resonance imaging (MRI) that combines a priori knowledge of anatomical shape with Convolutional Neural Networks (CNNs). The proposed approach incorporates 3D...
Effects of Proud Large Osteochondral Plugs on Contact Forces and Knee Kinematics: A Robotic Study.
The American journal of sports medicine
May 9, 2018
BACKGROUND: Osteochondral allograft (OCA) transplantation is used to treat large focal femoral condylar articular cartilage defects. A proud plug could affect graft survival by altering contact forces (CFs) and knee kinematics.
Please Don't Move-Evaluating Motion Artifact From Peripheral Quantitative Computed Tomography Scans Using Textural Features.
Journal of clinical densitometry : the official journal of the International Society for Clinical Densitometry
Aug 8, 2017
Most imaging methods, including peripheral quantitative computed tomography (pQCT), are susceptible to motion artifacts particularly in fidgety pediatric populations. Methods currently used to address motion artifact include manual screening (visual ...
Anatomic and non-anatomic anterior cruciate ligament posterolateral bundle augmentation affects graft function.
Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA
Jul 29, 2017
PURPOSE: The purpose of this study is to compare knee laxity and graft function (tissue force) between anatomic and non-anatomic posterolateral (PL) bundle augmentation.
Is an Anterolateral Ligament Reconstruction Required in ACL-Reconstructed Knees With Associated Injury to the Anterolateral Structures? A Robotic Analysis of Rotational Knee Stability.
The American journal of sports medicine
Jan 5, 2017
BACKGROUND: The effect of an anterolateral ligament (ALL) reconstruction on rotational knee stability and corresponding anterior cruciate ligament (ACL) graft forces using multiple knee loading conditions including the pivot-shift phenomenon has not ...
How Much Does the Anatomical Tibial Component Improve the Bony Coverage in Total Knee Arthroplasty?
The Journal of arthroplasty
Dec 27, 2016
BACKGROUND: Recently, anatomical designs in total knee arthroplasty are introduced to address asymmetry of the resected tibia cutting surface. It is still not well known how much improvement would be achieved in total knee arthroplasty, especially in...
The use of a robotic tibial rotation device and an electromagnetic tracking system to accurately reproduce the clinical dial test.
Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA
Feb 18, 2016
PURPOSE: The purpose of this study was to: (1) determine whether a robotic tibial rotation device and an electromagnetic tracking system could accurately reproduce the clinical dial test at 30° of knee flexion; (2) compare rotation data captured at t...
Assessment of knee laxity using a robotic testing device: a comparison to the manual clinical knee examination.
Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA
Dec 24, 2015
PURPOSE: The purpose of this study was to collect knee laxity data using a robotic testing device. The data collected were then compared to the results obtained from manual clinical examination.
Tibial rotation influences anterior knee stability--a robot-aided in-vitro study.
Clinical biomechanics (Bristol, Avon)
Dec 5, 2015
BACKGROUND: Anterior cruciate ligament rupture can lead to symptomatic instability, especially during pivoting activities, which are often associated with increased anterior and rotational tibial loading. Therefore, the purpose of our robot-aided in-...
