The present invention overcomes the problem of undesirable bone growth and/or unwanted scar tissue formation on the articulating surfaces and in the articulating spaces of prosthetic intervertebral discs. The invention comprises a method for preserving motion in a prosthetic disc having at least one articulating surface comprising applying an anti-infiltration agent on and around an articulating surface of the prosthetic disc. Suitable anti-infiltration agents include but are not limited to, hemostatic compounds, anti-adhesion compounds, bone-formation inhibiting compounds, or any combination thereof.
