Micro\u2010CT analysis showed a loss of trabecular bone in the unstable knee, compared with the contralateral knee, at all time points. At both 18 and 54 months, the differences in trabecular thickness and surface\u2010to\u2010volume ratio were greater than at 3 months. Although the mean subchondral plate thickness, especially in the medial aspect of the medial tibial plateau, was greater in the OA knee than in the contralateral knee 18 months and 54 months after ACLT, these differences were not statistically significant; however, the difference was significantly greater at 54 months than at 3 months.<\/jats:p>Conclusion.<\/jats:italic> Thickening of the subchondral bone is not required for the development<\/jats:italic> of cartilage changes of OA in this model. The bony changes that develop after ACLT, however, could result in abnormal transmission of stress to the overlying cartilage and thereby contribute to the progression<\/jats:italic> of cartilage degeneration.<\/jats:p>","DOI":"10.1002\/art.1780361019","type":"journal-article","created":{"date-parts":[[2007,2,15]],"date-time":"2007-02-15T00:48:57Z","timestamp":1171500537000},"page":"1460-1467","source":"Crossref","is-referenced-by-count":214,"title":["A longitudinal study of subchondral plate and trabecular bone in cruciate\u2010deficient dogs with osteoarthritis followed up for 54 months"],"prefix":"10.1002","volume":"36","author":[{"given":"D.
