Biomechanics in end-stage knee osteoarthritis: Dynamic measures provide deeper insight than radiographic alignment during functional tasks.

Static radiographic alignment fails to capture the dynamic nature of joint behaviour during functional tasks. To address this, our study evaluated the relationship between Hip-Knee-Ankle angle (HKAA) and dynamic biomechanical variables (dynamic HKAA (dHKAA), via projection of hip, knee, and ankle joint centers onto the frontal plane, knee adduction moment (KAM), and knee abduction angle (KAA)), during gait and sit-to-stand tasks with and without arm assistance. A further objective was to examine the mediolateral center of pressure (COP ML) as a complementary parameter for assessing joint loading and frontal plane alignment.

Repeated Heat Stress Modulates the Levels of the Mitokines MOTS-C and FGF21 in Active Men during Calf Muscle Immobilization.

Purpose: Heat stress, like exercise, can elicit beneficial mitochondrial adaptations and attenuate disuse muscle atrophy. The beneficial effects of heat therapy may in part be related to mitokines as they are released by the cells in response to perceived mitochondrial stress. This study thus investigated the effect of repeated heat exposures on mitokine response in the context of immobilization-induced muscle atrophy.

Lessons Learned from Implementing Injury and Illness Surveillance in Professional Football: Introducing a New Implementation Framework.

Injury and illness surveillance (IIS) systems play a crucial role in professional sports by monitoring athlete health, informing preventive strategies, and enhancing performance. Although international bodies, such as the International Olympic Committee, have established comprehensive guidelines, implementing these standards across diverse sports environments and specifically in football (soccer), remains challenging. This paper reflects on the experiences gained from implementing IIS systems in various football settings, including the Qatar Stars League and the Asian Football Confederation.

Diagnostic domains, differential diagnosis and conditions requiring further medical attention that are considered important in the assessment for Achilles tendinopathy: a Delphi consensus study.

The absence of agreed methods to diagnose Achilles tendinopathy impedes research and clinical practice. This gap results in heterogeneous and/or poorly described study samples, making it challenging to apply findings in clinical practice. The aim of this Delphi study was to define consensus on (1) diagnostic domains; (2) differential diagnoses; and (3) conditions requiring further medical attention, when assessing for Achilles tendinopathy.

Visual AbstractThis is a visual representation of the abstract.

DYNEELAX Robotic Arthrometer Reliability and Feasibility on Healthy and Anterior Cruciate Ligament Injured/Reconstructed Persons.

Background: Anterior cruciate ligament (ACL) injuries are commonly assessed using clinical examination and magnetic resonance imaging, but these methods have limitations in reproducibility and quantification. Instrumented laxity measurements using devices, like the DYNEELAX®, offer an alternative approach. However, to date, there is no human data on the DYNEELAX® and the reliability of these devices remains a subject of debate, and there is no consensus on appropriate knee tightening levels for testing.
