Question

Most common joint involved in septic arthritis:

• A. Knee
• B. Hip
• C. Shoulder
• D. Elbow

Answer 1

The Correct Option is A

Septic arthritis is an infection in a joint, commonly caused by bacteria. The condition is characterized by joint pain, swelling, and decreased range of motion. Among the various joints in the human body, the knee joint is the most frequently affected by septic arthritis.

Here’s a brief explanation:

1. Joint Structure: The knee joint, being large and more commonly involved in various activities, has a high susceptibility to infections.
2. Blood Supply: The rich blood supply in and around the knee joint can transport bacteria there more efficiently than to other joints.
3. Clinical Observations: Multiple clinical studies and patient reports have consistently shown a higher incidence of septic arthritis in the knee than in other joints such as the hip, shoulder, or elbow.

Thus, the most common joint involved in septic arthritis is the knee.
