Osteoarthritis - Insights From Recent Research.

Area of Science:

• Rheumatology
• Orthopedics
• Public Health

Background:

• Osteoarthritis (OA) is the most prevalent form of arthritis.
• Its increasing incidence in aging societies, particularly Korea, poses significant health challenges.
• Currently, no treatments exist to prevent or slow OA progression.

Purpose of the Study:

• To review current evidence on the etiopathogenesis of Osteoarthritis.
• To highlight Korean epidemiological findings and genetic studies in Asian populations.
• To examine sex differences in OA pain pathogenesis.

Main Methods:

• Review of epidemiological studies, focusing on Korean data.
• Analysis of recent genetic research, including genome-wide association and Mendelian randomization studies.
• Examination of literature on sex differences in pain signaling in OA.

Main Results:

• Epidemiological data from Korea provide unique insights into OA prevalence.
• Genetic studies reveal potential pathways involved in OA pathogenesis, with a focus on Asian populations.
• Sex-specific differences in pain mechanisms are increasingly recognized.

Conclusions:

• A comprehensive understanding of OA pathogenesis, integrating epidemiology, genetics, and pain signaling, is essential.
• Further research into these areas is critical for advancing therapeutic strategies for Osteoarthritis.
• Targeting specific pathways identified through genetic and sex-difference studies may lead to novel treatments.
