Effects of idiopathic flatfoot deformity on knee adduction moments during walking

Gait & Posture, 2021
Flatfoot deformity is commonly characterized by a subtalar valgus, a low medial longitudinal arch, and abduction of the forefoot. Although flatfoot deformity has been associated with lower first (KAM1) and second (KAM2) peak knee adduction moments during walking, the biomechanical connection remains unknown.We hypothesized that hindfoot eversion ...

Knee adduction moment and medial knee contact force during gait in older people

Gait & Posture, 2014
External knee adduction moment has been studied as a surrogate for medial knee contact force. However, it is not known whether adduction moment is a rational measure for predicting medial knee contact force. The aim of this study was to investigate the correlation between knee adduction moment and medial knee contact force in older people, using ...

A wearable sensor system for knee adduction moment measurement

2016 IEEE International Conference on Real-time Computing and Robotics (RCAR), 2016
Knee adduction moment is a key parameter that links with the severity of knee osteoarthritis. However, assessment of the knee adduction moment is commonly implemented through the stationary measurement systems in a gait laboratory. The purpose of this study is to develop a wearable sensor system that can be used to estimate the knee adduction moment. A

Effects of simple knee sleeves on pain and knee adduction moment in early unilateral knee osteoarthritis

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2019
Knee sleeves are often prescribed to alleviate pain in people with early knee osteoarthritis. However, the biomechanics underlying their pain-relieving effect are still not well understood. This pre–post study aims at evaluating and comparing the effects of two different types of knee sleeves on knee adduction moment.

Modelling knee flexion effects on joint power absorption and adduction moment

The Knee, 2015
Knee osteoarthritis is commonly associated with ageing and long-term walking. In this study the effects of flexing motions on knee kinetics during stance were simulated. Extended knees do not facilitate efficient loading. It was therefore, hypothesised that knee flexion would promote power absorption and negative work, while possibly reducing knee ...

Modified walking shoes for knee osteoarthritis: Mechanisms for reductions in the knee adduction moment

Journal of Biomechanics, 2013
The objective of this study was to examine mechanisms underpinning the reduction in knee adduction moment (KAM) and changes in frontal plane knee-ground reaction force (GRF) lever arm with a modified shoe that incorporates both a variable-stiffness sole and lateral wedging.

Foot rotation—A potential target to modify the knee adduction moment

Journal of Science and Medicine in Sport, 2006
Isolating the particular joints/limb segments associated with knee adductor moment variability may provide clinically important data that could help to identify strategies to reduce medial tibiofemoral joint load. The aim of this study was to examine whether or not foot and thigh rotation during human locomotion are significant determinants of knee ...

Abduction-adduction moments at the knee during stair ascent and descent

Journal of Biomechanics, 1996
To examine the relative magnitude of the knee abduction-adduction moments during stair climbing, ten normal subjects (average weight 660 N, leg length 0.962 m, height 1.74 m) were studied during repeated trials of stair ascent and descent. Data were collected using a four-camera video system and two forces plates incorporated within a flight of three ...

Kinematically aligned total knee arthroplasty reduces knee adduction moment more than mechanically aligned total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, 2017
Knee adduction moment (KAM) has been recognized as a good clinical surrogate for medial tibiofemoral joint loading and is associated with implant durability after total knee arthroplasty (TKA). This study aimed to examine the effects of joint line obliquity in kinematically aligned TKA (KA-TKA) on KAM during gait.The study enrolled 21 knees from 18 ...

Patient with knee osteoarthritis demonstrates improved knee adduction moment after knee joint distraction: a case report

Acta Orthopaedica Belgica
In this article we report a case of a 53-year-old patient diagnosed with end-stage osteoarthritis (OA) of the knee. The patient underwent treatment with knee joint distraction (KJD) with the aim to postpone total knee arthroplasty and prevent potential revision surgery.
