Clinical, radiological and survivorship results after ten years comparing navigated and conventional total knee arthroplasty: a matched-pair analysis.

Purpose: Our aim was to compare the long-term outcome between navigated and conventional total knee arthroplasty (TKA), which is currently not known.

Methods: Long-term survivorship, clinical scores and radiographic results of a matched-pair group of 350 patients (350 knees) treated with navigated (n = 157) or conventional (n = 188) TKA for osteoarthritis over a period of 11 years were reviewed retrospectively.

Results: The mean clinical follow-up was ten years.
