The purpose of this study was to determine the effects of bisphosphonates periprosthetic BMD in THA patients as a function of stem design. Specifically, the goals were to determine if bisphosphonates as a group could significantly inhibit periprosthetic bone loss, time needed to see an effect, if one drug was more effective than the others, and if there was a difference due to stem design or cement. Thirteen articles met the inclusion criteria. Overall, groups treated with bisphosphonate therapy preserved significantly more BMD than the control groups as early as six months postoperatively, and orally delivered bisphosphonates were most effective. Furthermore, the biggest differences were in patients with non-cemented stems, and of those, the largest differences were seen in patients with fully coated CoCr stems.
