A medical table provides the functionality needed for hip and knee arthroplasty at a cost that is acceptable for smaller patient care centers. Such a table can use a sliding mechanism to maintain traction during positioning of a patients leg. The table also can utilize a knee arthroplasty attachment to provide for precise knee positioning, such as by using a sliding assembly attached to a spar of the table. The table can include a pair of actuators providing for both lateral tilt and trendelenburg motions, which reduces the complexity from previous tables. The table also can include a removable power/control module, which allows for quick and easy replacement of damaged components.
