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 .
Five- to 12-year follow-up of a hydroxyapatite-coated, cementless total knee replacement in young, active patients.
We carried out a prospect i ve study of 118 hydroxyapatite-coated , cementless total knee replacements in patients who were < /= 55 years of age and who had primary ( 92 ; 78 % ) or post-traumatic ( 26 ; 22 % ) osteoarthritis . The mean period of follow-up was 7.9 years ( 5 to 12.5 ) . The Knee Society clinical scores improved from a pre-operative mean of 98 ( 0 to 137 ) to a mean of 185 ( 135 to 200 ) at five years , and 173 ( 137 to 200 ) at ten years . There were two revisions of the tibial component because of aseptic loosening , and one case of polyethylene wear requiring further surgery . There was no osteolysis or progressive radiological loosening of any other component . At 12 years , the overall rate of implant survival was 97.5 % ( excluding exchange of spacer ) and 92.1 % ( including exchange of spacer ) . Cementless total knee replacement can achieve excellent long-term results in young , active patients with osteoarthritis . In contrast to total hip replacement , polyethylene wear , osteolysis and loosening of the prosthesis were not major problems for these patients , although it is possible that this observation could change with longer periods of follow-up
