We examined the arthroprotective effects of the bisphosphonates alendronate and risedronate and the nonsteroidal antiinflammatory drug (NSAID) meloxicam.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Micro\u2010CT revealed reduced levels of periarticular trabecular bone loss in animals with knee triad injury treated with the bisphosphonate drugs alendronate or risedronate, or the NSAID meloxicam, compared with untreated animals. Alendronate treatment reduced bony osteophyte development. While risedronate as a monotherapy did not positively impact osteophytogenesis, combination therapy with risedronate and meloxicam reduced osteophyte severity somewhat. Micro\u2010MRI revealed an increased, diffuse water signal in the epiphyses of untreated rats with knee triad injury 8 weeks after surgery, suggestive of a bone marrow lesion\u2013like stimulus. In contrast, meloxicam\u2010treated rats showed a significant reduction in fluid signal compared with both bisphosphonate\u2010treated groups 8 weeks after surgery. Histologic analysis qualitatively confirmed the chondroprotective effect of both bisphosphonate treatments, showing fewer degradative changes compared with untreated rats with knee triad injury.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our findings indicate that select combinations of bisphosphonate and NSAID drug therapy in the early stages of secondary OA preserve trabecular bone mass and reduce the impact of osteophytic bony adaptations and bone marrow lesion\u2013like stimulus. Bisphosphonate and NSAID therapy may be an effective disease\u2010modifying drug regimen if administered early after the initial injury.<\/jats:p><\/jats:sec>","DOI":"10.1002\/art.27595","type":"journal-article","created":{"date-parts":[[2010,6,7]],"date-time":"2010-06-07T15:48:01Z","timestamp":1275925681000},"page":"2726-2735","source":"Crossref","is-referenced-by-count":82,"title":["In
