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 .
Femoral component migration in total knee arthroplasty: randomized study comparing cemented and uncemented fixation of the Miller-Galante I design.
The Miller-Galante I knee replacement was inserted in 25 women and three men ( 33 knees ) with osteoarthrosis . All patients received a TiAlV femoral component with a commercially pure titanium fiber-mesh undersurface . Cemented or cementless fixation was used based on a r and omization protocol . Micromotions of the femoral components were recorded with roentgen stereophotogrammetric analysis during the first 2 postoperative years . The magnitude of migration did not differ between cemented and uncemented fixation . The number of nonmigrating prostheses decreased from 21 ( 12 cemented and nine uncemented ) at 3 months to six ( three cemented and three uncemented ) at 24 months . In both groups , the magnitude of prosthetic tilting about the longitudinal axis ( internal-external rotation ) was as large as that about the transverse axis ( flexion-extension ) . Rotation into extension was as common as rotation into flexion . The largest translations were recorded at either of the posterior condyles . In 10 uncemented components , radiolucent lines were seen at the distal interface postoperatively . Proximal migration of the femoral component was recorded in these knees , and the width of the lines decreased or the lines disappeared totally at 24 months . After 2 years , lines were noted around four cemented and four uncemented replacements , mainly anteriorly or distally . All of these prostheses migrated . One prosthesis , revised because of malalignment , displayed pronounced migration after an initial period of stability . Bone ingrowth was observed anteriorly and anterodistally despite the presence of motions of 1 mm or more
