By the use of videoarthroscopy, the changes of the stifle joint after experimental rupture of cranial cruciate ligament (CCL) in dogs were evaluated and classified, based on the parameters found at the arthroscopic examination right before the rupture. By the arthroscopic examination, it was possible to visualize the remainings of the CCL and joint changes such as increase of the vascularity and synovial proliferation increase in the synovial membranes, as well as fibrillation and irregularities on the joint surfaces and osteophyte formation, mainly on the trochlear ridges. The results suggest that arthroscopy is a precise method for macroscopic evaluation of the smooth and bone joint tissues
