Abstract

Background: Despite cementless total knee arthroplasties (TKAs) have potential advantages over cemented TKAs, there are conflicting results. The purpose of the present study is to determine the long-term clinical and radiographic results, the survival rate, and the prevalence of osteolysis of cemented vs cementless TKAs. Methods: A total of 261 patients (522 knees) who underwent bilateral simultaneous TKAs were included in the present study (mean age, 62.5 ± 5.5 years). Patients were evaluated clinically, radiographically, and also using computed tomography scans. A mean follow-up period was 23.8 years (range, 22-25 years). Results: There were no significant differences between the Knee Society total score, change in total score, knee function score, and Western Ontario and McMaster Universities Osteoarthritis Index score in the 2 groups. In total, 8 knees (3%) were revised in the cementless group and 5 knees (2%) in the cemented group. Radiographs and computed tomography scans showed no femoral, tibial, or patellar osteolysis in either group. The rate of survival at 25 years was 97% (95% confidence interval [CI], 92%-100%) in the cementless group and 98% (95% CI, 94%-100%) in the cemented group, with reoperation for any reason as the end point. The rate of survival at 25 years was 98% (95% CI, 94%-100%), with reoperation for aseptic loosening as the end point in both groups. Conclusions: At this length of follow-up, cementless TKA has comparable outcomes and survivorship to cemented TKA.
