In septic arthritis management, what is often required due to rapid joint destruction?

• A. Surgical intervention (arthroscopy or open drainage).
• B. Physical therapy alone.
• C. Oral antibiotics only.
• D. Observation.

Answer: (A)

Septic arthritis causes rapid destruction of joint cartilage and surrounding structures, so quickly removing the infected material from the joint is essential. Draining the joint—either with arthroscopy or open drainage—physically removes purulent fluid, debris, and bacteria, reducing intra-articular pressure, inflammation, and the enzymatic damage that leads to cartilage destruction. This prompt surgical intervention, usually paired with intravenous antibiotics, improves the chance of preserving joint function and prevents irreversible damage.

Without drainage, options like physical therapy alone or antibiotics by mouth cannot adequately control the infection inside the joint or penetrate purulent fluid, and watching the joint risks rapid progression. Therefore, surgical drainage is the best approach to limit destruction and control the infection early.
