Crepitus is best described as:

Crepitus is best described as:

• A. Inflammation of the joints lining
• B. Joint cracking and/ or popping with motion
• C. Pain with resisted movement
• D. Excess synovial fluid production

Answer: (B)

Crepitus is the cracking or popping you can feel or hear in a joint as it moves. This sound or sensation happens when joints glide and the surfaces interact in ways that create a crackling feeling—often from gas bubbles in the synovial fluid popping or from roughened cartilage or tendons rubbing over bone during motion. It can occur in a normal, healthy joint or with degenerative changes like osteoarthritis, and it isn’t inherently about pain or inflammation. The other descriptions refer to different phenomena: inflammation of the joint lining (synovitis) is about swelling and irritation of the synovial membrane; pain with resisted movement points to muscle or tendon issues rather than a joint sound; excess synovial fluid production describes joint effusion with swelling, not the audible crackling.
