Kim YH, et al. - In this study, the long-term clinical and radiographic results, the survival rate, and the prevalence of osteolysis of cemented versus cementless total knee arthroplasties (TKAs) were ascertained. Researchers recruited a total of 261 patients (522 knees) who had undergone bilateral simultaneous TKAs in the present study (mean age, 62.5±5.5 years). They examined patients clinically, radiographically, and applying CT scans. In this study 23.8 years (range, 22 to 25 years) was a mean follow-up. The data demonstrated that cementless TKA has comparable outcomes and survivorship to cemented TKA at this length of follow-up.
