    Abstract:
    Thirty samples of articular cartilage taken during the operation from patients with incipient arthrosis, arthrosis with radiological modifications and arthrosis under study for Rheumatoid Arthritis (RA) were investigated using histopathological (HE, VG, PAS-Alcian, Gömöri, Safranine O) and electronmicroscopic techniques. The control material was made of posttraumatic cartilage (Moore prosthesis). Histopathologically, the incipient arthrosis cartilage had superficial exfoliations associated with reduced saframinophilic tinctorial perichondrocytic activity. The arthrosic cartilage with typical radiological modifications was individualized at the synovia-cartilage junction by villous aspects of the synovia associated with perichondrocytic gaps, reduction of safraninophilia and modifications of reticuline-collagenic network. The arthrosic cartilage under study for RA revealed destructive fibrous modifications of the synovia and severe affection of the articular cartilage at synovia-cartilage junction. Electronmicroscopically, the ultrastructural affection was minimum in the incipient arthrosis cartilage developing to chondrocytic degeneration in arthrosis with radiological correspondent. Both histopathological and ultrastructural data emphasize the fact that arthrosis is associated with synovitis following a primitive degenerative process similar to rheumathoid synovitis in arthrosis under study for RA.
