Infectious disorder of joint

An infectious disorder of a joint is an inflammatory condition of the musculoskeletal system caused by direct microbial invasion of the synovial space and articular tissues, commonly termed septic or infectious arthritis

An infectious disorder of a joint is an inflammatory condition of the musculoskeletal system caused by direct microbial invasion of the synovial space and articular tissues, commonly termed septic or infectious arthritis It primarily affects synovial joints—most frequently large weight-bearing joints such as the knee and hip—across pediatric, adult, and prosthetic-joint populations Pathophysiologically, pathogens (most commonly bacteria such as *Staphylococcus aureus*, as well as viruses, fungi,...

Pathophysiologically, pathogens (most commonly bacteria such as *Staphylococcus aureus*, as well as viruses, fungi, or mycobacteria) enter the joint via hematogenous seeding, direct inoculation, or contiguous spread

This triggers a severe inflammatory response with marked synovial fluid purulence, localized erythema, warmth, severe pain, restricted motion, and, if untreated, rapid cartilage degradation and subchondral bone destruction
