Implant survivorship for cementless TKA was comparable to the current gold st and ard cemented TKAs
Cementless  total knee arthroplasty ( TKA )  has had limited use in the United States , however , recent reports have demonstrated promising results , but there has been no meta- analysis to examine these outcomes in the past 5 years .
Results of cementless total knee arthroplasty in an older rheumatoid arthritis population.
Fifty-five total knee arthroplasties ( TKAs ) in thirty-nine adult ( mean age , 62 years ) patients with rheumatoid arthritis were studied prospect ively for a period of 1 - 7 years . All of the procedures were performed using cementless fixation of the tibial and femoral components . The Knee Society clinical rating system mean knee scores increased 56 points after operation ( mean , 88 points ) , and the mean functional scores increased 28 points ( mean , 64 points ) . Two revisions ( 4 % ) have been required , one for secondary late infection and one for failure of a cementless metal-backed patellar component . Good bone stock was retained in both , allowing for uneventful cementless revision . Forty-two arthroplasties ( 76 % ) were completely pain-free , twelve ( 22 % ) had mild , occasional discomfort with weight-bearing , and one ( 2 % ) had moderate pain at last examination . In this older rheumatoid population , cementless TKA offers good or excellent early clinical results and excellent preservation of bone stock should revision become necessary
