Objective: To explore the molecular mechanisms underlying meniscus degeneration.
Methods: We performed anterior cruciate ligament resection in the Hainan Wuzhishan pig to establish a meniscus degeneration model. We applied gene chip technology to detect differentially expressed genes (DEG) in the degenerative meniscus tissues. We applied Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway, core gene network, and relevant MicroRNA analyses to identify regulatory networks relevant to meniscus degeneration. We detected 893 differentially expressed genes, mainly involved in hormone production, apoptosis, and inflammation.
Results: We found that , inflammatory mediator regulation of TRP channels, , and may play a key role in the degenerative meniscus tissue.
Conclusion: We found that meniscus degeneration involves several molecular mechanisms and provide molecular targets for future research into the disease.

Background: Painful degeneration of the sternoclavicular joint refractory to nonoperative treatment has historically been managed with resection of the degenerative segment of the medial clavicle. Although this has produced good results with improvement in symptoms, recurrent pain necessitating revision surgery is not an infrequently encountered outcome. To reduce the occurrence of recurrent postoperative pain, a novel technique to reconstruct the intra-articular disc at the time of medial clavicle resection was developed.

Impaired autophagy is reported to promote osteoarthritis (OA). However, the mechanism by which autophagy in regulating meniscus degeneration and OA remains unclear. Here, unconvered aberrant energetic metabolism pattern in meniscus cells with OA is uncovered first, which results in lower adenosine triphosphate (ATP) production.

Background: Medial meniscus posterior root tears (MMPRTs) significantly contribute to knee dysfunction, leading to abnormal biomechanics and accelerated cartilage degeneration. Arthroscopic transtibial pullout and all-inside repair are two commonly used techniques for treating MMPRTs, each with unique advantages and limitations.
Objective: To compare the clinical and functional outcomes of the transtibial pullout and all-inside repair techniques in the treatment of MMPRTs, with a focus on postoperative recovery, knee function, and complications.

Background: In the context of osteoarthritis (OA), a condition marked by joint degeneration, there is a notable absence of efficacious approaches to promote regenerative healing in chondrocytes. Novel therapeutic strategies like nanomicelles-hydrogel microspheres loaded with Astragalus polysaccharide (GelMA@APPA) offer promising avenues for promoting chondrocyte regeneration and mitigating OA progression.
Methods: Astragalus polysaccharide (APS) has been shown to induce chondrocyte proliferation and promote cartilage matrix secretion, demonstrating biological activity associated with chondrocyte regeneration.
A Systematic Review and Meta-Analysis of Medial Meniscus Root Tears: Is Surgery the Key to Better Outcomes?

Medial meniscus root tears (MMRTs) are serious injuries that disrupt knee biomechanics, often accelerating cartilage degeneration and osteoarthritis when left untreated. These injuries are increasingly recognized as a major cause of knee pain and functional limitations, particularly among middle-aged and older adults. This systematic review and meta-analysis aimed to evaluate the outcomes of conservative management compared to surgical intervention for MMRT, focusing on pain relief, functional recovery, and the progression of osteoarthritis.
