Effects of joint lavage and steroid injection in patients with osteoarthritis of the knee: Results of a multicenter, randomized, controlled trial

Abstract

Compared with placebo, both treatments significantly relieved pain but did not improve functional impairment. The effects of the 2 treatments were additive. Cortivazol provided short-term relief of pain (up to week 4). The effects of joint lavage persisted up to week 24.
