title: Functional Results of the ROCC® Mobile Bearing Knee. 602 Cases at Midterm Follow-Up (5 to 14 Years).
abstract: 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.
