Abstract

Trephine reamers that include a body with a hollow interior sized to receive a femoral component. A distal end of the body includes one or more teeth shaped for cutting the femur. Valleys are positioned between the teeth. The valleys accommodate the cut bone and prevent and/or reduce interference with the cutting teeth. Thus, a single trephine reamer is able to cut a greater amount of bone. Methods of cutting the femur including positioning the trephine reamer over the femoral component, and rotating the reamer such that the teeth cut the bone that extends around the component. The reamer moves along the length of the component during the cutting thus allowing for removal of the component.
