Abstrakt: We report midterm results of a prospective continuous cohort of ROCC® Total Knee Arthroplasties (TKA). Between 2001 and 2008, all primary TKA patients (n = 500) received 602 ROCC saddle-shaped rotating platform TKAs. Mean follow-up was 7.5 years (5–13) (> 10 years in 123 knees). 82 patients (93 knees) died; 20 patients (21 knees) were lost to follow-up. Active flexion improved from 119° (10°–150°) to 127° (90°–155°) and Knee Society knee score from 39 ± 11 to 94 ± 9. Two knees were reoperated for aseptic loosening: Kaplan–Meier 14-year survivorship with aseptic loosening as end-point was 99.4% (95% CI, 99.8–100). UCLA mean score increased from 3.8/10 at baseline to 7.3/10 at last FU, 91% recovering pre-disease activity, and 27% with UCLA score ≥ 8/10. ROCC TKA demonstrated solid midterm survivorship without activity-related complications. Level of Evidence: Therapeutic, Level IV. [ABSTRACT FROM AUTHOR]
