Osteoarthritis and cartilage

Osteoarthr. Cartil. · Nov 2005
Second-look arthroscopy of cartilage changes of the patellofemoral joint, especially the patella, following acute and recurrent patellar dislocation.
The purpose of this study was to clarify some pathogenesis of the cartilage changes of the patellofemoral joint in patellar dislocation knees. ⋯ One of the pathogenesis of fissuring in RPD knees seems to be cracking occurring at the time of APD. Two of the pathogenesis of fibrillation may result from the reparative reaction of the cartilage in osteochondral defect site and the cartilage change due to a high degree of cracking damage mainly on the central dome in APD injury. The continuation of patellar dislocation definitely makes the patellar cartilage lesions worse.
