The aim of this study was to determine whether there is a difference in functional outcome between the PFC Sigma fixed-bearing and rotating-platform total knee replacement systems. One hundred twenty patients were randomised to receive either a fixed-bearing or rotating-platform PFC Sigma total knee replacement. Range of movement (ROM

We assessed the results of long cemented stems in patients over 65 undergoing a first time revision hip arthroplasty for aseptic loosening. 103 patients were followed up for a minimum of five years after revision surgery; 45% had EndoKlinik C grade preoperative bone loss. At final follow-up 31 patients had died, all but one with the prosthesis in situ. There were 71 revisions alive, one had been revised for a peri-prosthetic fracture. Of the 45 that had radiographs at a minimum of five years, three stems were probably or definitely loose according to the Harris classification. There was 92% patient satisfaction and a mean Oxford Hip Score (OHS) of 25/60 in the 59 patients that had not been revised and had full clinical follow-up. Long-stem cemented revisions for aseptic loosening in elderly patients allow immediate postoperative weight bearing and have good radiological and clinical outcomes.
