[Intra-articular injection. Substances and techniques].

Intra-articular injections are widely used in the treatment of joint pain and/or inflammation. Low costs, effectiveness, and safety are offered as possible reasons. The method remains controversial, as the evidence supporting the efficacy of these procedures has been poor. To evaluate intra-articular therapy, a meta-analysis of the efficacy of various agents injected intra-articularly was performed. Furthermore, indications and medications are discussed.
