All patients were then treated with piroxicam at 20 mg once daily, and clinical and gait analyses were repeated after 4 weeks.<\/jats:p><jats:p><jats:italic>Results.<\/jats:italic> Fifteen of the 18 patients studied had a significant increase in the knee adduction moment after treatment. In the group as a whole there was a significant increase in knee adduction moment (mean percent body weight times height [%BWTH] 4.11 pretreatment versus 4.57 after 4 weeks of treatment; <jats:italic>P<\/jats:italic> &lt; 0.01) and maximum quadriceps moment (mean %BWTH 2.13 pretreatment, 2.62 posttreatment; <jats:italic>P<\/jats:italic> &lt; 0.01), as well as changes in other gait parameters that might be expected to be altered as a result of relief of pain.

Whether the increased loading is due to the analgesic effects of the treatment is unknown, but if so, the development of agents capable of relieving pain while reducing loads at the knee may be desirable.<\/jats:p>","DOI":"10.1002\/art.1780360905","type":"journal-article","created":{"date-parts":[[2007,2,15]],"date-time":"2007-02-15T01:08:23Z","timestamp":1171501703000},"page":"1207-1213","source":"Crossref","is-referenced-by-count":152,"title":["Effect of piroxicam on gait in patients with osteoarthritis of the knee"],"prefix":"10.1002","volume":"36","author":[{"given":"Thomas J.","family":"Schnitzer","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jovan M.","family":"Popovich","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gunnar B.
