Recent studies have recognized the involvement of microRNA-155 (miR-155) in the pathogenesis of OA and most of its risk factors while also identifying the antidiabetic drug metformin as a potential modulator of disease progression. MiR-155, a key endogenous regulator of the immune system, mechano-transduction, and multiple genetic pathways, interacts with OA targets of cellular energetic and circadian homeostasis, promoting systemic and local articular inflammation, cartilage matrix degradation, and chondrocyte apoptosis. Metformin, widely used for type 2 diabetes, has demonstrated anti-inflammatory, anti-oxidative, and chondroprotective properties in OA, mainly through its activation of adenosine monophosphate-activated protein kinase and inhibition of nuclear factor kappa-B signalling. Enthrallingly, metformin targets the same cellular pathways as miR-155 with emerging evidence also suggesting miR-155 expression modulation, indicating synergistic, potentially disease-modifying effects in OA. This review highlights the central role of miR-155 in OA pathophysiology and its potential as a biomarker for disease diagnosis and progression.

Considering the anatomy of the ankle, these snapping phenomena can be categorized into four regional groups: (1) Lateral; (2) Medial; (3) Anterior; and (4) Posterior. Lateral ankle snapping, a common occurrence, typically results from peroneal tendon subluxation due to compromise of the superior and inferior peroneal retinacula, or from intrasheath subluxation, characterized by abnormal tendon motion within an otherwise intact retromalleolar groove and retinaculum. Medial ankle snapping primarily affects the posterior tibial tendon and can involve the flexor digitorum longus tendon. Anterior ankle snapping results from abnormal gliding of the tibialis anterior tendon, extensor digitorum longus tendon, peroneus tertius tendon, and inferior extensor retinaculum. Posterior ankle snapping typically involves the plantaris tendon and flexor hallucis longus (hallux saltans).
