“…No adverse events or complications related to the new material were seen. The observed rates of radiologic loosening and wear were similar to those in other studies of primary TKAs that had a similar length of followup [4,8,15,18]. Furthermore, we noted a slightly better patellar score in the nonresurfaced patella group; this difference just approached but did not achieve statistical significance.…”

“…Kim et al [27] reported that the survivorship of fixed-bearing TKA was 97.1 % at 12.6 years in patients with an average age of 58.6 years and that of mobilebearing TKA was 97.1 % at 14.1 years in patients with an average age of 55.7 years. Our survival rates are similar to the reported survival rates for TKA in younger patients [12,[24][25][26][27]. Baker et al [14] reported the survival rates of 80.7 % for the cemented press-fit condylar knee (PFC; DePuy, Warsaw, IN, USA) and 75.3 % for the cementless PFC knee (DePuy) at 15 years.…”

Purpose The purpose of this prospective, randomised study was to evaluate long-term clinical results, radiographic findings, complications and revision and survivorship rates in patients <55 years at a minimum of 16 years after undergoing bilateral, sequential, simultaneous, cemented and cementless total knee arthroplasties (TKAs) in the same patients. Methods Bilateral, sequential, simultaneous TKAs were performed in 80 patients (160 knees). There were 63 women and 17 men with a mean age of 54.3 years (range 49-55), who received a cementless prosthesis in one knee and a cemented prosthesis in the other. The mean follow-up was 16.6 years (range 16-17). Results At final review, the mean Knee Society (KS) knee scores (95.8 versus 96.9), Western Ontario and McMaster Universities (WOMAC) osteoarthritis (OA) index (25.4 versus 25.9), range of motion (ROM) (125°versus 128°), patient satisfaction (8.1 versus 8.3) and radiological results were similar in both groups. Femoral component survival rate was 100 % in both groups at 17 years; at 17 years, the cemented tibial component survival rate was 100 % and the cementless tibial component 98.7 %. No osteolysis was identified in either group. Conclusion Long-term results of both cementless and cemented TKAs were encouraging in patients with OA who were <55 years. However, we found no evidence to prove the superiority of cementless over cemented TKAs.

“…Although TKAs using fixed-bearing prostheses have produced long-term survival rates of 90% or greater at 15 years [12,25,27], numerous authors have reported long-term polyethylene wear and osteolysis [3,4,21,26,28,31,34]. A mobile-bearing prosthesis was introduced to reduce polyethylene wear and osteolysis [5,20].…”

Background Periprosthetic osteolysis is an increasingly prevalent complication of TKA. To reduce the polyethylene wear and periprosthetic osteolysis, particularly in young patients, the design of the contemporary fixed-bearing TKAs has been modified and mobile-bearing TKAs have been introduced. Questions/purposes We asked whether the prevalence of osteolysis would be less in well-functioning mobile-bearing TKAs than in well-functioning contemporary fixedbearing TKAs in young patients. Patients and Methods We compared 488 patients (894 knees) who received fixed-bearing knee prostheses with 445 patients (816 knees) who received mobile-bearing knee prostheses. There were 187 men and 301 women (mean age, 58.6 years; range, 33-65 years) in the fixedbearing group and 167 men and 278 women (mean age, 55.7 years; range, 33-65 years) in the mobile-bearing group. The mean followup was 12.6 years (range, 10-17 years) in the fixed-bearing group and 12.9 years (range, 10-17 years) in the mobile-bearing group. ResultsThe incidence of osteolysis was 1.6% (14 of 894 knees) in the fixed-bearing group and 2.2% (18 of 816 knees) in the mobile-bearing group at the final review. The mean postoperative Knee Society knee and function scores were 92.9 points and 83.5 points, respectively, in the fixedbearing group and 90.7 points and 83.8 points, respectively, in the mobile-bearing group. The revision rates were 3.7% (33 of 894 knees) in the fixed-bearing group and 2.7% (22 of 816 knees) in the mobile-bearing group. Conclusions We found the incidence of osteolysis, rate of revision, and implant survivorship were similar between fixed-bearing and mobile-bearing TKAs in younger patients. Level of Evidence Level III, therapeutic study. See the guidelines for authors for a complete description of levels of evidence.
