Functional outcomes

The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a survey instrument designed to assess patients’ opinions about their knee and associated problems. It is formatted as a brief, self-administered survey. It includes questions on five subscales: pain, other symptoms, function in daily living, function in sports and recreation, and knee-related quality of life. Numerical values are assigned to a series of response options, such as no pain, mild pain, moderate pain, severe pain and extreme pain, and mean scores are calculated using this data.

These data represent patients who were surveyed during 2012. It shows scores improved significantly from preoperative assessment to six-month postoperative assessment, and from preoperative assessment to one year postoperative assessment. The scores from six-month postoperative assessment to one-year postoperative assessment showed no significant difference.
