A Case of Infectious Arthritis due toStaphylococcus lugdunensisin Seronegative Rheumatoid Arthritis, Diabetes Mellitus Patient, after Intraarticular Hyaluronic Acid Injection

Abstract

Intra-articular hyaluronic acid injections for symptomatic treatment of osteoarthritis are widely used but can result in complications, such as infectious arthritis. Staphylococcus lugdunensis is a common normal skin flora but can cause severe infectious disease, such as infective endocarditis. We present the first report of infectious arthritis caused by methicillin-sensitive S. lugdunensis after intra-articular hyaluronic acid injection in an immunocompromised patient in Korea.
