← Human Body & HealthWhich outcome worsens osteoarthritis when joint friction rises?
A)Increased chondrocyte apoptosis✓
B)Enhanced collagen synthesis
C)Reduced synovial fluid viscosity
D)Elevated proteoglycan aggregation
💡 Explanation
Increased joint friction accelerates cartilage breakdown through greater biomechanical stress impacting articular chondrocytes. This causes increased apoptosis because cell necrosis dominates rather than extracellular matrix repair; therefore, chondrocyte loss increases osteoarthritis severity.
