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 .
Simultaneous cemented and cementless total knee replacement in the same patients: a prospective comparison of long-term outcomes using an identical design of NexGen prosthesis.
The purpose of this prospect i ve , r and omised study was to evaluate the clinical and radiological results comparing the identical cemented or cementless NexGen total knee prostheses implanted bilaterally in the same patient . Sequential simultaneous bilateral total knee replacements  were performed in 50 patients ( 100 knees ) . There were 39 women and 11 men with a mean age of 58.4 years ( 51 to 67 ) who received a cemented prosthesis in one knee and a cementless prosthesis in the other .  The mean follow-up was 13.6 years ( 13 to 14 ) . At final review , the mean Knee Society scores ( 96.2 ( 82 to 100 ) versus 97.7 ( 90 to 100 ) ) , the mean Western Ontario and McMaster Universities osteoarthritis index ( 34.5 ( 4 to 59 ) versus 35.6 ( 5 to 51 ) ) , the mean ranges of knee movement ( 124 ° ( 100 ° to 140 ° ) versus 128 ° ( 110 ° to 140 ° ) ) , mean patient satisfaction ( 8.1 ( SD 1.9 ) versus 8.3 ( SD 1.7 ) ) , and radiological results were similar in both groups . The rate of survival of the femoral components was 100 % in both groups at 14 years . The rate of survival of the cemented tibial component was 100 % and 98 % in the cementless tibial component .  No osteolysis was identified in either group . Our data have shown no advantage of cementless over cemented components in total knee replacement
