A prosthesis system for replacing a knee joint between a femur and a tibia can include a femoral component, a tibial component, a bearing, a first yoke, and a first key. The method comprises providing a map for translating primary data storage locations on said primary storage device to secondary data storage locations on said secondary storage device and utilizing said map to enable data stored on said secondary storage device to mirror data stored on said primary storage device. Each storage device forms a network-connected storage node on the network so that data acquired at any data acquisition node may be applied to the network and stored at any storage node during a data recording session. The requested collection of style rules is to be suitable for use with a document-based web page. As a result, the performance of the transportation and storage can be therefore increased, while the cost is reduced.
