ABSTRACT
PURPOSE: To evaluate the survival rate and long term clinical outcomes of hybrid total knee arthroplasty (TKA). MATERIALS AND METHODS: We retrospectively analyzed 113 hybrid TKAs (NexGen) in 86 patients that were followed for more than 10 years. Kaplan-Meier survival curves were generated using revision as an end point. Knee Society Score (KSS) and range of motion were evaluated for clinical assessment and plane radiographs were used to evaluate implant problems. RESULTS: At 11.2 years (range, 10 to 12.2 years) of follow-up on average, 7 knees required revision. The reason for revision was aseptic loosening in 4 knees (1 in femoral and tibial component and 3 in tibial component only) and infection in 3 knees. The survival rate was 93.8% at 12 years for all knees, and 96.5% when septic loosening was excluded. The KSS improved from 29.3 to 91.5 in the Cruciate-Retaining type (CR) and from 21.5 to 90.3 in the posterior stabilizing type (PS) at latest follow-up. The average range of motion was improved from 120.6degrees to 133.8degrees in the CR type and 119.5degrees to 135.5degrees in the PS type. CONCLUSIONS: Hybrid TKA provides good survival rates and clinical results comparable to cemented TKA.
