摘要: We measured the early adaptive bone remodeling of distal femur prospectively for 1 year after uncemented total knee arthroplasty (TKA) in 29 knees with primary arthrosis. 18 patients were randomized to receive a PCA Modular® femoral component (n 9) or modified version same prosthesis an altered location porous coating. other 11 11) formed consecutive series Duracon® component. trabecular above component, mineral density (BMD) was 2 regions interest (ROI) anteriorly fixation pegs (RO11) and (ROI 2), using dual photon absorptiometry (DPA). There no differences between Modular regarding postoperative decrease BMD.
