In fact, there is a paucity of comparisons in the literature of patients and outcomes with current generation MMSRs and THA. The following investigation is a comparative study of patient demographics, preoperative clinical condition, and postoperative outcome across these two procedures. We hypothesize that the functional benefits of MMSR are due, at least in part, to patient-related variables, such as age and general health status. Materials and Methods
