Patients undergoing non-cemented total hip arthroplasty with a Zimmer Fiber Metal Taper Stem and who meet the inclusion and exclusion criteria are offered the informed consent process. Those consenting are randomized following surgery by flip of a coin into one of two groups: Weight Bearing as Tolerated or Toe Touch Weight Bearing Only. Each patient is followed for two years, and is seen at 6 weeks, 3 months, 1 year and two years. Questionnaires are completed including the Harris Hip Score and the SF-36. Patients complete a compliance survey to determine behavior related to their study group assignment and compliance with their study group. Radiographs are obtained at each post-operative interval and subsidence is evaluated and recorded. Range of motion and ambulation are assessed and recorded also.
