The concentrations of Gentamicin in the serum, drainage fluid and urine were determined by radioimmunoassay in 40 patients after total hip replacement and 10 after knee replacement. Palacos R bone cement with added Gentamicin had been used to fix the prostheses in all cases. Two types of response were observed; in Group I the Gentamicin levels rose very rapidly, whereas in Group II a more gradual increase was seen. In all cases the level of Gentamicin had fallen to a negligible amount by the fifth day after operation.
