A modular prosthetic device is provided for replacement of the knee. The device is assembled from a plurality of components, each of which can be inserted through a small incision. After inserting the components through the incision, the device can be assembled within the knee cavity. The modularity of the device enables a surgeon to replace only those regions of the knee that are diseased or damaged, thereby avoiding a complete knee replacement. If, at a later time, additional regions of the knee become diseased or damaged, those additional regions of the knee can be replaced by additional device components and those additional components can be connected to the previously implanted components. By replacing only those regions of the knee that are diseased or damaged and by implanting each of the components through the small incision, the surgery is minimally invasive and, therefore, requires reduced time for healing and rehabilitation.
