Objective
To synthesize recent advances in developmental biology, mechanobiology, metabolism, and tissue engineering as they relate to cartilage biology and osteoarthritis (OA).
Design
Narrative review integrating peer-reviewed studies covering chondrocyte ontogeny, mechanical and metabolic regulation, disease pathogenesis, and regenerative strategies.
Results
SOX9+ progenitors persist postnatally and contribute to cartilage and bone repair. Mechanotransductive signaling through TRPV4 and PIEZO1 ion channels, together with cytoskeletal regulators, orchestrate cartilage matrix remodeling and inflammation. Metabolic rewiring driven by TGF-β, HIF1α, and fatty acid oxidation programs is critical for joint development and OA pathology. Sex-linked lipidomic signatures and enhancer reprogramming shape disease risk and response. Engineered tissues using nasal chondrocytes and transcriptional enhancers offer repair potential.
Conclusions
OA arises from disruption of conserved developmental, metabolic, and mechanical programs. Targeted interventions restoring transcriptional fidelity, metabolic balance, and tissue mechanics offer translational promise.

OBJECTIVETo quantitatively analyze the effects of long-term simulated bed rest unloading on knee articular cartilage using quantitative magnetic resonance imaging (fMRI), alongside functional and subjective outcomes.METHODSIn this prospective cohort study, 23 healthy men (mean age 32.7 ± 5.2 years) completed a 60-day, -6° head-down bed rest (HDBR) protocol. The primary endpoints, knee cartilage T2 relaxation time and thickness, were assessed using a 3.0T MRI system before and after HDBR. Data were analyzed with linear mixed-effects models. Secondary outcomes included isokinetic muscle strength, thigh circumference, dynamic balance (Y-Balance Test), and patient-reported outcomes (International Knee Documentation Committee score, Lysholm Knee Score, Self-rating Anxiety Scale, and Self-rating Depression Scale).RESULTSHDBR induced a decrease in the knee-averaged cartilage T2 relaxation time (mean change, -0.67 ms; 95% CI, -1.22 to -0.11; p = 0.018). In contrast, no clear effect on cartilage thickness was observed (mean change, -0.054 mm; 95% CI, -0.159 to 0.050; p = 0.307). Functional and subjective outcomes indicated declines in muscle performance and functional scores.CONCLUSIONS60 days of simulated microgravity led to a decrease in knee cartilage T2 relaxation time without changes in thickness, suggesting early matrix alterations. These findings, together with observed neuromuscular deficits, highlight the need for protective strategies during prolonged unloading.

The role of the sympathetic and sensory nervous systems in the development and progression of osteoarthritis (OA) is widely recognized, as is the fact that these systems can influence each other. However, the nature of sympathosensory interactions during OA progression remains unclear. In this narrative review, we provide an overview of scientifically proven or putative sympathosensory interactions at the peripheral, spinal, and central levels. We highlight the factors that determine direct or indirect coupling types and describe the signaling and cross-signaling mechanisms of interaction at these different peripheral and central levels. Additionally, we discuss the clinical relevance of possible sympathosensory interactions in OA by introducing a new biopsychosocial OA model emphasizing the vicious cycle of chronic local and systemic inflammation, chronic pain, sleep deprivation, and chronic stress. These interrelated processes also underlie and contribute to common comorbidities such as hypertension and obesity and are unified by a state of autonomic imbalance marked by sympathetic dominance.

Objective
To investigate the associations between whole joint cartilage and meniscal morphology on MRI and radiographic joint space width (JSW) measures and in knee osteoarthritis (KOA), to determine whether bicompartmental measures demonstrate stronger associations than unicompartmental ones, and to evaluate their correlations with Kellgren and Lawrence grading.
Design
A cross-sectional analysis of baseline radiographs and MRIs from 262 KOA participants in the prospective, multicenter IMI-APPROACH cohort was conducted. Radiographic measures included minimum joint space width (mJSW), fixed location JSW (JSW(x)), mean JSW, and joint line convergence angle (JLCA), assessed using fully automated software. JSW was evaluated both unicompartmentally and bicompartmentally. Cartilage morphology, full-thickness cartilage loss, meniscal extrusion, tears, and maceration were assessed using the semi-quantitative MRI Osteoarthritis Knee Score to summarize whole-joint cartilage and meniscal morphology. Associations of radiographic measures with MRI outcomes were assessed using multivariable linear regression; Spearman correlations with Kellgren and Lawrence (KL) were also evaluated.
Results
MRI-defined meniscal maceration was associated with unicompartmental and bicompartmental JSW measures. Full-thickness cartilage loss was associated with unicompartmental (95% CI [-0.16;-0.02]) and bicompartmental mJSW (95% CI [-0.14;-0.02]), and JLCA (95% CI [0.04;0.22]). Models explained 32–39% of variance for unicompartmental and 23–45% for bicompartmental measures (R²). Bicompartmental measures showed stronger correlations with KL grading than unicompartmental measures (95% CI: –0.31 to –0.02).
Conclusions
Associations between whole-joint cartilage and meniscal degeneration are similar for uni- and bicompartmental JSW, with bicompartmental JSW showing stronger correlations with KL grades. These findings support including both compartments in radiographic assessment to improve structural evaluation in KOA.
