@visual.healthlab: The mechanical reality of severe joint degeneration under the surface. When the structural foundation of the foot undergoes rapid bone erosion and cartilage loss, every single step creates direct bone-on-bone friction. This dramatic visualization shows the progression of advanced osteoarthritis and osteoporosis happening simultaneously. The protective cushioning completely wears away, leaving a porous, weakened bone structure subjected to intense joint tension and friction pulses with every movement. Whether caused by extreme wear and tear over time or structural wasting, losing joint integrity completely alters natural gait and mobility.
