Cement versus cementless fixation in total knee arthroplasty

A prospectively studied group of 55 uncemented Press Pit Condylar total kne e arthroplasties was compared retrospectively with a matched group of 51 ce mented Press Fit Condylar total knee arthroplasties at a mean of 10 years a fter operation. For the cemented group, the pain and function scores improv ed from 32 and 45 preoperatively to 95 and 77, respectively. For the unceme nted group the scores improved from 33 and 50 preoperatively to 93 and 60, respectively. There were 10 revisions in the uncemented group for femoral o r tibial aseptic loosening or osteolysis compared with two revisions in the cemented group. Exclusive of problems related to patellar metal backing, s urvival to revision for aseptic failure or radiographic loosening was 72% i n the uncemented group and 94% in the cemented group at 10 years. A signifi cantly higher revision rate was found in the uncemented compared with cemen ted total knee arthroplasty of the Press Fit Condylar design.
