| WOMAC(Western Ontario and McMaster Universities) Scores | A tool to evaluate patient function associated with knee. The WOMAC measures five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68). The total score is summed from individual sections, and 0 is the best possible score. | minimum 10 year follow up after the index surgery |
