Lack of benefit of intraarticular glucocorticoid injections for knee osteoarthritis
Although limited evidence suggests that intraarticular glucocorticoid injections for knee osteoarthritis (OA) may result in short-term pain relief, data for longer-term outcomes are less favorable. A randomized trial including 140 patients with symptomatic knee OA and ultrasound features of synovitis found that pain reduction was no different comparing injections of 40 mg triamcinolone acetonide with placebo every 12 weeks for two years [1]. Furthermore, two years of triamcinolone injections resulted in greater cartilage volume loss. These findings do not support intraarticular glucocorticoid injections in patients with symptomatic knee OA and are consistent with our practice. In addition, we discourage the use of serial injections (eg, every three months) due to progressive cartilage damage in knee OA patients.
