Abstract

The aim of this study was to determine outcomes and survivorship of the Triathlon knee replacement up to 5 years post-operation. A cohort of 266 patients receiving a Triathlon knee replacement were assessed before surgery and at 3 months, 1 year, 2 years, 3 years and 5 years post-operation. Assessments included patient-reported outcome measures, American Knee Society Score, complications and survivorship. The largest improvements in pain, function, stiffness and knee-related quality of life occurred in the first 3 months post-operation. Further smaller improvements were reported between 3 and 12 months post-operation, and then a plateauing of outcomes was observed up to 5 years. A high percentage of patients (86%) were satisfied with their outcome at 5 years. Survivorship with revision as the endpoint was 96.6% (95% CI 93.2-98.1%) at 5 years post-operation. In conclusion, this study observed good mid-term patient outcomes and survivorship of the Triathlon knee replacement.
