\u201cIn this large, randomized controlled trial of cemented vs. uncemented knees with all patella resurfaced, we were unable to show a difference in clinical outcomes, but we showed an equivalent outcome between cemented and uncemented knees at 5 years for patient-reported outcomes, revision rates and radiographic outcomes,\u201d Simon <\/b>W. <\/b>Young, MD, FRACS,<\/b> from the University of Auckland, told Healio about results presented at the American Academy of Orthopaedic Surgeons Annual Meeting.<\/p>\n
\n
In the study, which received the Mark Coventry Award at the AAOS Annual Meeting Specialty Day, Young and colleagues randomly assigned 316 patients aged younger than 75 years undergoing primary TKA to receive either cemented (n = 158) or fully uncemented (n = 158) implants with patella resurfacing. According to the abstract, revision and reoperation rates, patient-reported outcome measures and incidence of radiolucent lines at 5 years were considered the primary outcome measures.<\/p>\n
In his presentation, Young said both groups had one revision for periprosthetic joint infection and one patient in the uncemented group had an extensor mechanism failure. No patients in the uncemented group and one patient in the cemented group had progressive radiolucent lines at 5 years. He also said more patients in the cemented group had nonprogressive radiolucent lines vs. the uncemented group.<\/p>\n
\u201cThese were largely minor lines that were probably not clinically relevant,\u201d Young said. \u201cImportantly, we did not see lines around the uncemented patellar component, which was perhaps the component we were most worried about.\u201d<\/p>\n
The researchers found no differences in manipulation under anesthesia, minor wound complications or patient-reported outcome measures between the two groups. Results showed a small difference in surgical time between the groups, according to Young.<\/p>\n
\u201cOur level 1, randomized controlled trial is reassuring and, as long as registry data confirms these findings across the wider population, it will be informative and likely drive a change in practice,\u201d Young told Healio.<\/p>\n
