AI Article Synopsis
- - The study investigated the impact of a specific postoperative shoe, the Medishoe, on knee adduction moments during walking, following concerns from previous literature about rigid-soled shoes potentially affecting knee mechanics.
- - Researchers used advanced technology, including force plates and motion capture systems, to compare the gait of ten healthy subjects wearing and not wearing the Medishoe, measuring knee adduction moments and related angles.
- - Results showed no significant difference in the knee adduction moment or related angles between the two conditions, although there was some indication of a trend worth further exploration with larger sample sizes and more complex modeling.
Article Abstract
Background/purpose: On a background of literature suggesting that certain rigid soled shoes may increase the knee adduction moment during gait this study was performed to look at specific postoperative shoe - the Medishoe. This shoe is used on a daily basis in a district general hospital orthopaedic department for patients post-operatively to protect wounds and fixations.
Methods: Using force plates and an opto-electronic motion capture system with retroreflective markers the knee adduction moment was estimated in ten healthy subject both with and without the shoe during normal gait. The angle at which the ground reaction acted with respect to the ground in the coronal plane as well as the tibiofemoral angle were also calculated using the Qualsys software - both with and without the Medishoe.
Results: Two-tailed paired t-tests using a 95% confidence interval showed that there was no significant difference between the two groups in the estimated knee adduction moment (p = 0.238), tibiofemoral angle (p = 0.4952) and the angle of the ground reaction force to the ground (p = 0.059).
Conclusion: There was no significant difference in the estimated knee adduction moment between the two groups, although there was a statistical trend to an alteration in the angle of the ground reaction force. Further work involving a greater number of subjects and a three dimensional model would further answer the question as to whether these or other post-operative shoes have a significant effect on the knee adduction moment.

A dynamic knee function scoring system for anterior cruciate ligament injuries based on normative six-degree-of-freedom gait pattern.
BMC Musculoskelet Disord

Sports Medicine Center, West China Hospital, Sichuan University, Chengdu, China.
Background: Traditional examinations of anterior cruciate ligament (ACL) injuries focus primarily on static assessments and lack the ability to evaluate dynamic knee stability. Hence, a dynamic scoring system for knee function is needed in clinical settings. This study aimed to propose a dynamic scoring system based on a large sample of normative six-degree-of-freedom (6-DOF) knee kinematics during gait, and validate its correlation with conventional outcome measurements in assessing ACL-injured knees.

Background: Varus thrust is common in those with knee osteoarthritis. Varus thrust is traditionally identified with visual analysis or motion capture, methods that are either dichotomous or limited to the laboratory setting. Inertial measurement unit data has been found to correlate with motion capture measures of varus thrust in those with severe knee osteoarthritis, allowing for a quantitative and accessible way of measuring varus thrust.

Nothronychus graffami was a large therizinosaur represented by a single well-preserved individual from the Turonian Tropic Shale of southern Utah. It is characterized by an enlarged abdomen, small tail, and an extensively pneumatized axial skeleton, and is frequently regarded as herbivorous. Given the overall tail reduction and the development of a wide fused synsacrum with widely spaced acetabulae, it is reconstructed with an anteriorly rotated femur and a displaced resting ground reaction force anterior to the center of mass.

Background: Knee osteoarthritis (KOA) is a prevalent musculoskeletal disease affecting joint mechanics. Considering the effect of step-width changes on the biomechanics of gait, especially the alteration of stability dynamics during narrow-base gait, this study investigated the kinematic parameters of the lower extremities during both normal and narrow-base walking in individuals with and without KOA.
Methods: A cross-sectional study with 20 individuals with bilateral KOA and 20 controls was conducted.
