A case‐control study and meta‐analysis reveal the association between COX‐2 G‐765C polymorphism and primary end‐stage hip and knee osteoarthritis

摘要

Osteoarthritis (OA) is a popular arthrosis featured as pain, limited joint activity, and deformity. Cyclooxygenase‐2 (COX‐2) has been reported to be up‐regulated in arthritic tissues and is integral to the progression of osteoarthritis (OA). Previous studies showed the COX‐2 promoter G‐765C polymorphism could influence COX‐2 expression. However, the relationship between the variant and OA risk is contrasting.
