Cement Spacer Molds for Knee

Cement spacer moulds for knee



The two-part Cempadic® silicone spacer moulds offer the surgeon the opportunity to prepare intraoperative cement spacers whose geometry corresponds to the ACS® knee prosthesis and its articulating surfaces are smooth enough to allow for a wear-reduced passive mobilization during treatment. The Cempadic® spacer moulds are subsequently processed and resterilized as conventional instruments for re-use.
Compared to the alternative offered pre-fabricated cement spacers, the use of Cempadic® moulds offers the possibility to mix the bone cement intraoperatively with specific antibiotics to accelerate healing of infections.


Cempadic® knee spacer moulds are in femoral and tibial sizes from 2 to 5 available. The femoral moulds exist each in left and right version.


It is recommended to use bone cement with standard viscosity, such as  implabond®, for making the cement spacers. The mixing of the bone cement and the application can be done by hand or by means of a mixing system and cement syringe.

Advantages of the use of cement spacers

In the case of infected revision interventions, all implant components are usually removed during the two-stage surgery, and the resulting joint spaces are filled with intraoperatively prepared pads or spacers made of bone cement. The spacers, which are loaded with antibiotics, are usually formed by hand and are generally not allowed to passively mobilize in the patient since the surfaces of the articulating spacers are incongruent and not smooth enough. After successful healing of the infections, these spacers are removed in a second surgery and replaced with new implant components.
