increased susceptibility to induced arthritis ( J:243715 )

• 8 week old mice are more susceptible to surgically induced osteoarthritis in knees than controls

• 4 weeks post-surgery articular cartilage is eroded and the region develops ectopic chondrocyte hypertrophy and is lacking Safranin O-staining proteoglycans and lubricin

osteoarthritis ( J:243715 )

• knee articular cartilage is thin, eroded and almost absent in joints of 6-7 month old mice

• tibial plateau exhibits arthritic changes based on osteoarthritis assessment criteria

• knee joint surface of the femur exhibits arthritic changes based on osteoarthritis assessment criteria

abnormal articular cartilage morphology ( J:243715 )

• knee articular cartilage is thin, eroded and almost absent in joints of 6-7 month old mice
