Cemented versus cementless fixation of a tibial component in LCS mobile-bearing total knee arthroplasty performed by a single surgeon.

Although cemented tibial fixation of total knee arthroplasty accepted as the gold standard, cementless fixation as a means to supplement disadvantages of cemented fixation continues to be of interest to clinicians. One hundred sixty-eight consecutive knees undergoing primary knee arthroplasty for osteoarthritis were randomly assigned to receive either a cemented (86 knees) or cementless (82 knees) fixation of tibial component. We report the outcomes at 8 to 11years (mean, 9.5). The mean KSS, the HSS score, the mean WOMAC, the mean ranges of knee movement and radiological results were similar in both groups. No osteolysis was identified in either group. The rate of survival of the femoral and tibial components was 100% in both groups at final follow-up.
