Bouchard's nodes (on the proximal interphalangeal joints) nodules on the proximal interphaleneal joints

Enlarged edematous joints Smooth shiny skin

Normal function of cartilage Focal trauma to cartilage

Chondrocyte injury and release of degration enzyme

Destruction of cartilage; loss of proteoglycan aggregates

Loss of tensile strength

Microfracture of subchondral bone with loss of compressibility Abnormal cartilage function

DIAGNOSIS Normally done in x-ray
