Wearable devices realize health monitoring, information transmission, etc. In this study, the human-friendliness, adaptability, reliability, and economy (HARE) principle for designing human energy harvesters is first proposed and then a biomechanical energy harvester (BMEH) is proposed to recover the knee negative energy to generate electricity. The proposed BMEH is mounted on the waist of the human body and connected to the ankles by ropes for driving. Double-rotor mechanism and half-wave rectification mechanism design effectively improves energy conversion efficiency with higher power output density for more stable power output. The experimental results demonstrate that the double-rotor mechanism increases the output power of the BMEH by 70% compared to the single magnet-rotor mechanism. And the output power density of BMEH reaches 0.07 W/kg at a speed of 7 km/h. Furthermore, the BMEH demonstrates the excitation mode detection accuracy of 99.8% based on the Gate Recurrent Unit deep learning model with optimal parameters.

Introduction: More extensive and cohesive studies on quadriceps tendon rupture (QTR) repair surgery are required to guide effective treatment strategies. Therefore, in this study, we aimed to identify predictors of subjective functional recovery following QTR repair surgery.
Materials And Methods: This multicentre retrospective cohort study enrolled 191 adults (age ≥ 18 years) who underwent surgical unilateral QTR repair (2010-2022) and had ≥ 1-year postoperative follow-up at three trauma centres in Germany.

Arterial diseases (ADs) are a significant health problem, with high mortality and morbidity rates. Endovascular interventions, such as balloon angioplasty (BA), bare-metal stents (BMSs), drug-eluting stents (DESs) and drug-coated balloons (DCBs), have made significant progress in their treatments. However, the issue has not been fully resolved, with restenosis remaining a major concern.

C-type natriuretic peptide (CNP) can be a new disease-modifying anti-osteoarthritis drug (DMOAD) candidate because intraarticular injection of CNP attenuates both articular cartilage degradation and persistent pain in a rat knee arthritis model. This study aimed to elucidate the underlying molecular mechanisms by which CNP protects the knee joint from osteoarthritic changes. Gene expression analyses indicated that CNP did not interfere with the expression of IL1β -responsive genes in rat primary synovial fibroblasts or the monocytic cell line, RAW264.

Background: Many patients with a lower limb socket-suspended prothesis experience socket-related problems, such as pain, chronic skin conditions, and mechanical problems, and as a result, health-related quality of life (HRQoL) is often negatively affected. A bone-anchored prosthesis can overcome these problems and improve HRQoL, but these prostheses have potential downsides as well. A valid and reliable tool to assess potential candidates for surgery concerning a favorable risk-benefit ratio between potential complications related to bone-anchored prostheses and improvements in HRQoL is not available yet.

Background/objectives: Football players have a high injury risk due to the physical demands of their profession, which can negatively affect their quality of life (QoL) in the long term. The aim of this study is to characterize the severe injuries that former Portuguese football players suffered throughout their professional careers and investigate the resulting impacts on the physical domain of QoL after retirement.
Methods: This study includes 84 former Portuguese football players (48.
