摘要

Purpose: Total knee arthroplasties typically have excellent survivorship (>95%) at 10 to 20 years. Implant manufacturers are attempting to address patient dissatisfaction with prostheses that recreate natural knee kinematics, which could lead to improved functional scores while still providing stability and durability. The purpose of this study was to review the outcomes of the first 100 consecutive patients who underwent a cruciate-retaining TKA.
Methods: The first 100 consecutive primary total knee arthroplasties using the TriathlonTM total knee system performed by one surgeon between 2005 and 2007 were identified: 56 women and 32 men, mean age of 59 years (range, 31-83 years). Patients were followed for a mean of 36 months (range, 24-61 months). Subsequent procedures and complications were reviewed.
Results: The survival rate in the study cohort was 98% (96 of 98 knees). The mean Knee Society objective and functional scores for this cohort was 89 (range, 56-100 points) and 86 (range, 45-100 points) points, respectively, having improved from 59 (range, 34-67 points) and 55 (range, 10-80 points) points preoperatively. All failures occurred within the first 40 cases performed with the new total knee system. The next 60 cases had 100% survivorship.
Conclusions: Excellent clinical outcomes and functional scores were found in patients who underwent a new cruciate-retaining TKA. Functional scores reported at a minimum of 2 years follow-up were comparable and often superior to published results of previous cruciate-retaining knee designs.
