Comparison of 2 Dosages of Intraarticular Triamcinolone for the Treatment of Knee Arthritis: Results of a 12-week Randomized Controlled Clinical Trial.

Abstract

To determine whether a double dose of intraarticular triamcinolone acetonide is more effective for knee arthritis than a 40-mg dose. In this 12-week randomized controlled clinical trial, 40 mg and 80 mg of intraarticular triamcinolone acetonide were compared in patients with knee arthritis. Evaluated variables included a Likert burden scale, visual analog scale pain scale, degree of arthritis activity, presence of swelling, and presence of functional limitation. Ninety-seven patients were randomized. No significant differences were observed between the groups regarding any outcomes. An 80-mg dose of triamcinolone acetonide had no additional benefit compared with 40 mg as treatment for knee arthritis. Nederlands Trial Register; trial registration number: NTR2298.
