Oxford Knee Score

Oxford Knee Score

A patient-reported outcome instrument which contains 12 questions on activities of daily living that assess function and residual pain in patients undergoing total knee replacement (TKR) arthroplasty. The OKS was designed, developed and validated by workers in public health and at the University of Oxford. It is short, reproducible, valid and sensitive to clinically important changes in patients’ clinical status. Its development was driven by the need for more systematic and accurate monitoring of post-TKR patient outcomes.

Pros
Patient reported, minimising bias by surgeons assessing the results; short, simple and summative; provides a single number value; can be completed on any medium—paper, computer or platform—facilitating follow-up of large cohorts.

Oxford Knee Score
1. How would you describe the pain you usually have in your knee?
    None = 4 points; severe = 0 points
2. Have you had any trouble washing and drying yourself (all over) because of your knee?   
    No trouble at all = 4 points; impossible = 0 points
3. Have you had any trouble getting in and out of the car or using public transport because of your knee (with or without a walking aid)?
    No trouble at all = 4 points; impossible = 0 points
4. For how long are you able to walk before the pain in your knee becomes severe (with or without a walking aid)?
    No pain for 60+ minutes = 4 points; not at all = 0 points  
5. After a meal (sat at a table), how painful has it been for you to stand up from a chair because of your knee?
    Not at all painful = 4 points; unbearable = 0 points
6. Have you been limping when walking because of your knee?
    Rarely = 4 points; all of the time = 0 points
7. Could you kneel down and get up again afterwards?
    Yes, easily = 4 points; no, impossible = 0 points
8. Are you troubled by pain in your knee at night in bed because of your knee?
    Not at all = 4 points; every night = 0 points
9. How much has pain from your knee interfered with your usual work (including housework)?
    Not at all = 4 points; totally = 0 points
10. Have you felt that your knee might suddenly ”give away” or let you down?    
    Rarely = 4 points; all the time = 0 points
11. Could you do the household shopping on your own?
    Yes, easily = 4 points; impossible = 0 points
12. Could you walk down a flight of stairs?
    Yes, easily = 4 points; impossible = 0 points

Grading the Oxford Hip Score
0 to 19—May indicate severe knee arthritis. See orthopaedic surgeon.
20 to 29—May indicate moderate to severe knee arthritis. See GP for an assessment and x-ray. Consider seeing orthopaedic surgeon.
30 to 39—May indicate mild to moderate knee arthritis. Consider seeing GP for an assessment and possible x-ray. Patient may benefit from non-surgical treatment—e.g., exercise, weight loss and/or anti-inflammatory medication.
40 to 48—May indicate satisfactory joint function. May not require any formal treatment.
