Thirty per cent. iopax, dissolved in a five-tenths per cent. procaine solution was used to visualize knee joints in a small number of cases. This solution did not cause serious reactions and was quickly absorbed from the joints. The method seems safe and, while it has been used only for diagnostic purposes, it may even yield therapeutic results. The solution used produced a hyperaemia of the synovial membrane, but no cellular exudate.
