Abstract

Background: Till today, Cemented Fixation in Total Knee Arthroplasty (TKA) is significantly more used than Hybrid or Uncemented Fixation. The purpose of this study was to compare Cemented, Uncemented and Hybrid Fixation of the ACS Mobile Bearing TKA at Mid-term follow-up. Methods: This study was an extended data report of our prospective single-center, single-blinded randomized controlled clinical trial comprising 105 patients. The primary outcome was survival at five years of follow-up calculated by Kaplan–Meier and Log-rank test. The secondary outcome was function based on patient-reported outcome measures (PROMs). Results: Eighty-three patients were included, of which 25 belonged into group A (Cemented), 28 in group B (Uncemented), and 30 in group C (Hybrid). Mean follow-up was 5.8 ± 0.7 (range 5–7) years. The 5-year survival rates were 96.8% (95%CI: 90.5; 100) in the Cemented group, 94.2% (95%CI: 86.4; 100) in the Uncemented group, and 93.8% (95%CI: 85.4; 100) in the Hybrid group for revision for any reason (p = 0.80). Functional outcome was similar among the groups. Conclusion: In our cohort of ACS Mobile Bearing TKA, there was no difference between Cemented, Uncemented, and Hybrid Fixation with regard to survival and function at Mid-term follow-up.
