A spacer for a knee replacement prosthesis. The spacer may include a lower surface, which has a locking component adapted to interlock with a tibial tray, an upper surface, the upper surface having a pair of condyle support platforms; and a frame positioned therebetween for anchoring the upper and lower surfaces thereto, the frame having a hollowed center defined by internal cavities. In some exemplary embodiments, the spacer may further include a fluid delivery system for localized antibiotic treatment to the surrounding joint. The delivery system may include a reservoir disposed within the internal cavity, a septum operatively connected to the reservoir, and fluid delivery element for dispensing a liquid medicament from the reservoir to the surrounding infection. The fluid delivery system may interact with external components to refill, communicate with, and control the system. |
