Adaptive properties of the articular cartilage and plasticity of its structures under various conditions of static-dynamic loading on joints have been studied when the data obtained in sables and minks, living in natural biocenosis and in cages, are compared. By means of optic, raster electron microscopy and microroentgenological analysis, peculiarities of structural formation of the articular cartilage have been revealed in ontogenesis, as well as succession in formation of its zonal architectonics. Conditions of prolonged hypodynamia are manifected as a number of anomalies in distribution of the cartilagenous integument of the joints affecting cellular and tissue levels of adaptation.

Osteoarthritis (OA) is a degenerative musculoskeletal disease, featured by the destruction of articular cartilage. Oxidative stress, one of the drivers of the extracellular matrix degradation in cartilage, plays a vital role in OA pathogenesis. Senkyunolide I (SEI) is a natural compound with a prominent anti-oxidative stress property against multiple diseases.

As not every patient with dysplasia will require a hip arthroscopy to obtain desired clinical improvement in the setting of periacetabular osteotomy, a challenge is identifying which patients require adjacent procedures (either via arthroscopic or open) to fully treat their hip pathology. Even though labral repair is the most reported arthroscopic procedure in cases of hip dysplasia, I would suggest that labral treatment is the least likely helpful component of hip arthroscopy in these cases.

The articular cartilage is characterized by its gradient hierarchical structure, which exhibits excellent lubrication and robust load-bearing properties. However, its inherent difficulty in self-repair after damage presents numerous formidable challenges for cartilage repair. Inspired by the unique structure of articular cartilage, a biomimetic bilayer hydrogel composed of PAM (polyacrylamide) and PAM/SA (sodium alginate) is prepared using a two-step in-situ swelling method.

Cartilage degradation is the hallmark of osteoarthritis (OA). The purpose of this study was to identify and validate differentially expressed genes (DEGs) in human articular cartilage that could serve as potential therapeutic targets for hip OA. We performed transcriptomic profiling in a discovery cohort (12 OA-free and 72 hip OA-affected cartilage) and identified 179 DEGs between OA-free and OA-affected cartilage after correcting for multiple testing (P < 2.
