Intra-articular corticosteroid injections provide short-term pain reduction in knee OA
Study Type: Meta analysis
OE Level of Evidence: 2
Journal Level of Evidence: N/A
Why was this study needed now?
Knee osteoarthritis is a prevalent condition in the adult population that is expected to place an increasingly large burden on the healthcare system as the population ages. There are a number of conservative treatments commonly used in the management of this condition that do not have strong evidence supporting their use. A synthesis of randomized controlled trials evaluating the use of corticosteroid injections in the management of knee osteoarthritis was needed to provide the best estimate of efficacy via meta-analysis.
What was the principal research question?
Does the use of an intra-articular corticosteroid injection reduce pain, without increasing adverse events, when compared to placebo injections in patients with knee osteoarthritis?
|Data Source:||Medline, the Cochrane Library, and EMBASE were searched for relevant articles published up to December 2002. The search engine Google was also used to search for relevant trials.|
|Index Terms:||Index terms used included "osteoarthritis", "knee", "corticosteroid" and "glucocorticoids", and "intra-articular OR intraarticular".|
|Study Selection:||Randomized trials and systematic reviews were considered if they specifically evaluated intra-articular steroid injection for knee osteoarthritis. Included studies focused on long-acting, potent forms of depo-corticosteroid (triamcinolone hexacetonide, methylprednisolone, betamethasone, and cortivazol). Studies needed to include a placebo arm to be considered for inclusion. A total of 5 RCTs, with data sampled from 312 patients, were selected for final inclusion.|
|Data Extraction:||Methods not reported. Means and standard deviations and 95% confidence intervals were extracted when available.|
|Data Synthesis:||RevMan software was used to perform the meta-analysis using both dichotomous and continuous outcomes.|
