What measurement means for total knee replacement care

There are more than 700,000 total knee replacement surgeries performed in the United States each year. By 2030, an estimated 3.5 million procedures will be performed annually due to the nation’s aging population and increasing obesity. Candidates for total knee replacement often have severe destruction of the knee joint associated with progressive pain and impaired function.

One way for your provider to assess your knee pain, function and mobility, and the impact on your daily activities is by using the Oxford Knee Score (OKS) assessment. The OKS can help both you and your doctor understand the level of pain you are experiencing. It asks 12 questions about your daily living activities in various areas, including level of pain; self-care; getting in/out of car; length of time able to walk; sitting; kneeling; night pain; interference with normal work; limping; and ability to climb or descend stairs.

Based on your answers, the score reflects the severity of the problems with your knee. The higher the score, the better your knee function is. Assessing the function and pain in your knee helps to identify the treatment options that are right for your individual needs.

The Total Knee Replacement: Assessing Symptoms measure reports how many patients answered questions about their knee problems before and after total knee replacement surgery.

The statewide rate of use of the OKS tool before and after surgery by all reporting medical groups is 27%​. This means 27 of 100 patients who had total knee replacement surgery completed a survey about their knee pain, function and mobility before and after surgery.

How we calculate the report

We measure how many patients completed the Oxford Knee Score (OKS) assessment before total knee replacement and one year after total knee replacement. The OKS asks 12 questions about knee pain, function and mobility.

This report is based on surgeries performed between January 1 and December 31, 2017. This information is collected under the measure name Total Knee Replacement.
