← Human Body & HealthWhich acute outcome occurs when joint effusions limit synovial fluid lubrication?
A)Increased articular cartilage frictional degradation✓
B)Elevated subchondral bone density formation
C)Reduced capsular ligament tensile strength
D)Decreased hyaluronan proteoglycan aggregate viscosity
💡 Explanation
Increased joint effusion volume causes a reduction in adequate synovial fluid, leading to increased FRICTIONAL DERADATION within the articular cartilage because excessive compressive forces increase friction. Therefore, option A occurs, rather than changes in density or other structural properties.
