Abstract
A femoral reamer (100) can include a base material (304) and a coating (302) disposed on the base material. The coating can be harder than the base material and, as a result, the femoral reamer can wear more slowly than if the coating was absent. The coating can be a different color than the base material. When the coating is worn off, such wear can be easily observed from a visual inspection of the femoral reamer. The coating can have an initial thickness (i.e., a thickness prior to use) that is related to a tolerance on a size and/or a shape of a hole drilled by the femoral reamer. When the coating is worn off, the size and/or the shape of the hole drilled by the femoral reamer may be at or near an edge of a specified tolerance range. The femoral reamer can be part of a kit and a method.
