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 .
Excellent fixation achieved with cementless posteriorly stabilized total knee arthroplasty.
Cementless posteriorly stabilized ( PS ) total knee arthroplasty has not been widely accepted primarily because of prior unpredictable results and concern about micromotion at the tibial fixation interface caused by the cam/post interaction . A prospect i ve consecutive series of 114 cementless , tricompartmental periapatite-coated single-radius PS implants in 110 patients with a mean age 62 years was performed to determine if initial stability and biologic fixation could be achieved . At a mean follow-up of 36 months , all implants demonstrated radiographic evidence of stable biologic fixation with no evidence of loosening , osteolysis , stress shielding , or progressive radiolucent lines . Based on these early results , cementless , periapatite-coated single-radius PS total knee arthroplasty offers marked promise
