Knee injury and Osteoarthritis Outcome Score (KOOS)
Your knee during the last week
This survey asks for your view about your knee. This information will help us keep track of how you feel about your knee and how well you are able to do your usual activities. Answer every question by ticking the appropriate box, only one box for each question. If you are unsure about how to answer a question, please give the best answer you can.
These questions should be answered thinking of your knee symptoms during the last week.
1Do you have swelling in your knee?
2Do you feel grinding, hear clicking or any other type of noise when your knee moves?
3Does your knee catch or hang up when moving?
4Can you straighten your knee fully?
5Can you bend your knee fully?
The following questions concern the amount of joint stiffness you have experienced during the last week in your knee. Stiffness is a sensation of restriction or slowness in the ease with which you move your knee joint.
6How severe is your knee joint stiffness after first wakening in the morning?
7How severe is your knee stiffness after sitting, lying or resting later in the day?

Scoring the KOOS
For the practitioner. Detach before handing the questionnaire to a patient.
| Scale | How | Range | Score |
|---|---|---|---|
| Symptoms | Add up items 1–7, divide by 28 and multiply by 100 | 0–100 | |
| Pain | Add up items 8–16, divide by 36 and multiply by 100 | 0–100 | |
| Function in daily living | Add up items 17–33, divide by 68 and multiply by 100 | 0–100 | |
| Function in sport and recreation | Add up items 34–38, divide by 20 and multiply by 100 | 0–100 | |
| Knee-related quality of life | Add up items 39–42, divide by 16 and multiply by 100 | 0–100 |
Each subscale is scored from 0 (extreme knee problems) to 100 (no knee problems). The KOOS publishes no cut-offs, and a total score is not validated: read each subscale on its own, and over time.
