Reduced Muscle Strength Can Alter the Impact of Gait Modifications on Knee Cartilage Mechanics

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Muscle strength can substantially influence knee joint loading, stability, and cartilage biomechanics, all of which are important factors in the onset and progression of knee osteoarthritis (KOA). Noninvasive rehabilitation methods, such as gait modifications, are suggested to effectively alter knee joint loading, potentially helping to ...

Anatomy and Physiology of Hamstring Injury [PDF]

International Journal of Sports Medicine, 2012
The hamstring muscles were analyzed anatomically and physiologically to clarify the specific reasons for the incidence of muscle strain of the hamstrings. For the anatomical study, hamstring muscles of 13 embalmed cadavers were dissected. For the physiological study, the knee flexor torque and surface electromyographic (EMG) signals were measured ...

No difference in osteoarthritis, but less graft failures after 5 years, comparing anatomic double‐bundle to anatomic single‐bundle ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this study was to compare the incidence of knee osteoarthritis (OA) between the anatomic single‐bundle (SB) and anatomic double‐bundle (DB) anterior cruciate ligament (ACL) reconstruction technique after 5‐year follow‐up (FU).

The tibial insertion of the hamstring can be considered to be preserved during anterior cruciate ligament reconstruction

Frontiers in Surgery, 2022
BackgroundHamstring as a graft was very common in anterior cruciate ligament reconstruction surgery. Usually the hamstring muscles needed to be taken out and then woven to be used.AimIn order to investigate whether it was beneficial for patients to ...

Gender-Based Analysis of Hamstring and Quadriceps Muscle Activation During Jump Landings and Cutting [PDF]

, 2010
This study evaluated gender differences in the magnitude and timing of hamstring and quadriceps activation during activities that are believed to cause anterior cruciate ligament (ACL) injuries.

How statistically fragile are randomized controlled trials comparing quadriceps tendon autografts with hamstring or bone‐patellar tendon‐bone autografts in anterior cruciate ligament reconstruction?

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To determine the statistical fragility of randomized controlled trials (RCTs) which compare the use of quadriceps tendon (QT) autografts to either hamstring tendon (HT) or bone‐patellar tendon‐bone (BPTB) autografts in anterior cruciate ligament reconstruction (ACLR).

The Acute Effect of Match-Play on Hip Isometric Strength and Flexibility in Female Field Hockey Players

Applied Sciences, 2020
The aim of this study was to determine the acute effect of simulated field hockey match-play on isometric knee flexion, adductor (ADD) and abductor (ABD) strength, adductor/abductor (ADD/ABD) strength ratio, countermovement jump height (CMJ), hip flexion

Association between passive stiffness of hamstring and eccentric knee flexion angle-torque relationship

Journal of Physical Fitness and Sports Medicine, 2021
Larger hip flexion range of motion with knee extension (hip flexion ROM) and passive stiffness of the hamstring is associated with greater production of isometric and concentric knee flexion torque at longer muscle lengths.
