Injection of triamcinolone versus saline in patients with knee osteoarthritis

Study Type: Therapy
OE Level of Evidence: 2
Journal Level of Evidence: N/A
Synopsis
16 patients (24 knees) with knee osteoarthritis were randomized to an injection with either 20mg triamcinolone hexacetonide or placebo. After 1 week, patients initially administered a triamcinolone hexacetonide injection received a saline injection, and patients initially administered a saline injection received a triamcinolone hexacetonide injection.

Why was this study needed now?
At the time this study was conducted there were few high-quality trials that had evaluated the efficacy of corticosteroid injections in the management of patient with knee osteoarthritis in comparison to a placebo injection.
What was the principal research question?
Does an intra-articular injection with triamcinolone hexacetonide reduce pain, function, and stiffness when compared to a placebo injection in patients with knee osteoarthritis?
Population: 16 patients with unilateral or biliateral symptomatic knee osteoarthritis (n=24 knees) (Mean age: 65.0+/-8.1). A non-crossover RCT was also reported on in the publication, but only the results of the crossover RCT will be reported on in this ACE Report.
Intervention: CS group: Patients were administered an injection of 1mL 20mg triamcinolone hexacetonide for the first injection. One week later, patients were administered an injection of 1mL saline. (n=12 knees).
Comparison: Saline group: Patients were administered an injection of 1mL saline for the first injection. One week later, patients were administered an injection of 1mL 20mg triamcinolone hexacetonide(n=12 knees)
Outcomes: Outcome measures included pain on a visual analog scale, duration of knee stiffness in the morning, joint tenderness on a 4 point scale, and patient opinion and preference between knees.
Methods: RCT; Crossover.
Time: Patients were assessed at baseline prior to injection, 1 week after the first injection, and 1 week after the second injection.
