Clinical Outcome following Intra-articular Triamcinolone Injection in Osteoarthritic Knee at the Community: A Randomized Double Blind Placebo Controlled Trial.

Background Knee pain is one of the common complaints patients present with in any community based health camps and Osteoarthritis of knee is a usual diagnosis. Injecting a long acting steroid is a common practice to alleviate the symptoms of osteoarthritic knee. Objective To evaluate the clinical outcome of injecting Triamcinolone acetenoid in osteoarthritis of knee in a community set up over a randomized double-blind placebo control trial. Method A prospective, randomized, double blind, placebo control trial was carried out in community after obtaining the ethical clearance from the IRC. Patients with clinically diagnosed osteoarthritis of knee were injected either Triamcinolone or Placebo after recording the baseline scores of the knee by Knee injury and Osteoarthritis Outcome Score (KOOS) - Physical Function Short form (KOOS-PS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Visual Analogue Scale (VAS). The same tools were used at two, six and at twelve weeks post injection to evaluate the functional outcome and pain. Result One hundred and seventeen patients were available for analysis among which, 55(48.7%) patients received Triamcinolone and 58(51.3%) received placebo. The baseline status of knees of two groups was comparable at the start of study. There was significant pain relief in the group receiving Triamcinolone at two and six week but not in twelve weeks. Group receiving placebo had pain relief only for first two weeks. Functional outcome was significantly improved compared to baseline in both the groups until six weeks however, in the triamcinolone group, it was significant until twelve weeks. No major complications were noted. Conclusion Intra-articular injection of Triamcinolone acetenoid is effective in symptoms control and improving functional outcome in clinically diagnosed osteoarthritis of knees in community set up during health camps.
