## Indications for use
Spacer-K is indicated for use as a temporary total knee replacement (TKR) for skeletally mature patients undergoing a two-stage procedure due to a septic process. Spacer-K is only indicated for an implantation period of 180 days or less. Because of the inherent mechanical limitations of the device material (gentamicin/polymethylmethacrylate), Spacer-K is only indicated for patients who will consistently use traditional mobility assist devices (e.g. crutches, walkers, canes) throughout the implantation period.
