Plain English Summary

Background and study aims
Steroids can be used in the treatment of patients with knee osteoarthritis (arthritis of the knee), but the best agent is still unknown. This study aimed to compare the effect of two drugs (triamcinolone hexacetonide and methylprednisolone acetonide) on the condition.

Who can participate?
Men and women who are at least 40 years old, with painful knee osteoarthritis took part in this study.

What does the study involve?
Participants were randomly allocated to receive a single knee injection of either triamcinolone hexacetonide or methylprednsilone acetonide. After 24 weeks participants attended a follow-up visit to assess the effectiveness of the treatment with questionnaires.

What are the possible benefits and risks of participating?
Possible benefits were pain relief and physical function improvement. Risks were related to the injection and included pain, swelling, bleeding and infection in the knee.

Where is the study run from?
The study was run from Hospital Heliópolis, São Paulo, Brazil

When is the study starting and how long is it expected to run for?
The study started in December 2010 and ended in May 2013

Study information

Scientific title

A randomized, double-blind study to evaluate the efficacy of intra-articular injection of methylprednisolone versus triamcinolone hexacetonide in patients with knee osteoarthritis


Study hypothesis

Intra-articular injections of methylprednisolone acetate and triamcinolone hexacetonide have similar efficacy at reducing knee pain and improving physical function both in the short as in the long-term in patients with symptomatic knee osteoarthritis.
