title: Early lesions of the articular surface in a strain of mice with very high incidence of spontaneous osteoarthritic-like lesions.
abstract: Our study was designed to see if the lesions of the articular surface represent an early event in the development of some types of articular degeneration. We examined the ultrastructural appearance of the articular surface labelled in vitro with cationized ferritin in several age groups of a substrain of C57BL/6 mice that develop a high incidence of osteoarthritic-like lesions. We found that as early as the age of 2 1/2 months the articular femoral and patellar surfaces presented abnormalities that became more severe with age. Alterations of the articular surface is a precocious event in this type of osteoarthritic-like degeneration.
