Septic arthritis is seen most commonly in which joint?

Explanation:
Septic arthritis is an acute infection of the joint space that usually reaches the joint through the bloodstream. The knee is the joint most often affected in adults because it has a large synovial cavity and a rich blood supply, making it more susceptible to hematogenous seeding and rapid infection progression. Clinically, this presents with a hot, swollen, very painful knee and limited range of motion, which is why the knee stands out as the most common site. Prompt joint aspiration and antibiotic treatment are essential to prevent cartilage damage and other complications.
