Average change in functional status following total knee replacement surgery
STEWARD: MN Community Measurement
Measure Description:
For patients age 18 and older undergoing total knee replacement surgery, the average change from pre-operative functional status to one year (nine to fifteen months) post-operative functional status using the Oxford Knee Score (OKS) patient reported outcome tool.
Numerator Statement:
There is not a traditional numerator for this measure; the measure is calculating the average change in functional status score from pre-operative to post-operative functional status score. The measure is NOT aiming for a numerator target value for a post-operative OKS score.

For example:
The average change in knee function was an increase of 15.9 points one year post-operatively on a 48 point scale.
Denominator Statement:
