33 patients scheduled for bilateral total knee arthroplasty were randomized to receive a titanium alloy implant in one knee and a cobalt-chromium implant in the other knee. The purpose of this study was to examine and compare periprosthetic bone mineral density (BMD) over 2-year follow-up. When considering tibial periprosthetic BMD, scans taken in the anteroposterior (AP) plane demonstrated signi...
