Abstract: | A radiographic scoring system for features of osteoarthritis of the canine stifle joint was devised. Intra- and inter-rater agreement was assessed by calculation of unweighted kappa statistics. "Global score," "effusion," "osteophytosis," and "intra-articular mineralization" were all features that had acceptable reliability, but "subchondral sclerosis" did not. The scoring system was used in a 13-month prospective study of the radiographic progression of osteoarthritis of the stifle joint, secondary to cranial cruciate ligament deficiency, in 58 dogs. In the index stifle joints all features were characterized by significant change over time, but osteophytosis had the greatest degree of change. In addition, 40% of contralateral joints showed progressive osteophytosis. |
