Osmic acid was first used by von Reis and Swensson in 1951 for the treatment of knee effusion [1]. It is an aqueous solution of osmium tetroxide, which is a vigorous oxidizing agent that has a high affinity for lipids and coagulates proteins. It is deposited in inflamed synovial tissue and subsynovial fat.
