A randomized clinical trial evaluated the efficacy of oral diacerein in reducing knee pain among symptomatic knee osteoarthritis patients with MRI-confirmed effusion-synovitis. Conducted across four Australian centers, the study involved 262 adults averaging 54.9 years of age, comparing diacerein against a placebo over 24 weeks. Both groups displayed similar reductions in pain and functionality, with quality of life measures favoring the placebo. Adverse effects, particularly gastrointestinal issues, were more pronounced in the diacerein group. Ultimately, diacerein showed no significant improvement over placebo, questioning its benefit in this subset of patients.
