Spacer® K

Interim knee prostheses

The Spacer® by Tecres is a Gentamicin-enriched femorotibial interim prosthesis which is implanted temporarily during two-stage revision procedures performed due to infection. It is a two-element spacer similar to a congruent condylar knee prosthesis. The femur part rests and moves upon the tibia part, which consists of a flat base. The two components are secured to the femur condyles and the tibia plateau with bone cement.
