Quasi optimal sagittal gait of a biped robot with a new structure of knee joint [PDF]

, 2013
The design of humanoid robots has been a tricky challenge for several years. Due to the kinematic complexity of human joints, their movements are notoriously difficult to be reproduced by a mechanism. The human knees allow movements including rolling and

Effect of surface matching mismatch of focal knee articular prosthetic on tibiofemoral contact stress using finite element analysis

Bone & Joint Research, 2023
Aims: Focal knee arthroplasty is an attractive alternative to knee arthroplasty for young patients because it allows preservation of a large amount of bone for potential revisions.

Knee replacement

The Lancet, 2012
Knee-replacement surgery is frequently done and highly successful. It relieves pain and improves knee function in people with advanced arthritis of the joint. The most common indication for the procedure is osteoarthritis. We review the epidemiology of and risk factors for knee replacement.

Bi-unicondylar arthroplasty: a biomechanics and clinical outcomes study

Bone & Joint Research, 2021
Aims: Bi-unicondylar arthroplasty (Bi-UKA) is a bone and anterior cruciate ligament (ACL)-preserving alternative to total knee arthroplasty (TKA) when the patellofemoral joint is preserved.

Chondrocalcinosis is common in the absence of knee involvement [PDF]

, 2012
Introduction: We aimed to describe the distribution of radiographic chondrocalcinosis (CC) and to examine whether metacarpophalangeal joint (MCPJ) calcification and CC at other joints occurs in the absence of knee involvement.

Reliability and validity of pose estimation algorithm for measurement of knee range of motion after total knee arthroplasty

Bone & Joint Research, 2023
Aims: We aimed to assess the reliability and validity of OpenPose, a posture estimation algorithm, for measurement of knee range of motion after total knee arthroplasty (TKA), in comparison to radiography and goniometry.

Impact of the diaphyseal femoral deformity on the lower limb alignment in osteoarthritic varus knees

Bone & Joint Open, 2023
Aims: The impact of a diaphyseal femoral deformity on knee alignment varies according to its severity and localization. The aims of this study were to determine a method of assessing the impact of diaphyseal femoral deformities on knee alignment for the ...

Persistent Biomechanical Alterations After ACL Reconstruction Are Associated With Early Cartilage Matrix Changes Detected by Quantitative MR. [PDF]

, 2016
BackgroundThe effectiveness of anterior cruciate ligament (ACL) reconstruction in preventing early osteoarthritis is debated. Restoring the original biomechanics may potentially prevent degeneration, but apparent pathomechanisms have yet to be described.

The Knee of the Cosmic Hydrogen and Helium Spectrum below 1 PeV Measured by ARGO-YBJ and a Cherenkov Telescope of LHAASO [PDF]

, 2015
The measurement of cosmic ray energy spectra, in particular for individual species, is an essential approach in finding their origin. Locating the "knees" of the spectra is an important part of the approach and has yet to be achieved.

Associations of physical activity with the risks of osteoarthritis and subtypes: a population-based cohort study of UK Biobank data

Bone & Joint Research
Aims: This study aimed to investigate the relationship between physical activity (PA) and the risk of osteoarthritis (OA) and its subtypes. Methods: We included participants from the UK Biobank aged 37 to 73 years from February 2006 to June 2010 ...
