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.

The patients were evaluated with the International Knee Documentation Committee Score (IKDC) and the Oxford Knee Score (OKS) in the preoperative and postoperative controls.
After 6 months, all the 54 cases were assessed by Oxford knee score.
Al patients showed a statistically significant improvement in the Knee Society clinical rating system, Western Ontario and Mc-Master Universities Osteoarthritis Index, and Oxford knee score. Ninety-four percent of patients were able to perform age-appropriate activities with average knee flexion of 120 degrees and 98 percent of patients reported pain relief to be excellent, very good, or good.
The aim of this study was to translate the site/ disease specific 12-item patient-reported Oxford Knee Score into Persian with the focus on its validation.
All the patients were reviewed in the months of February and March 2014 with Oxford knee score (OKS) questionnaire [12].
The primary outcome measure used was patient-reported kneeling ability, assessed in particular by question 7 of the Oxford Knee Score (Dawson et al 1998, Murray et al 2007).
For example, a postal survey of 8331 TKA patients who underwent surgery in England in 2003 found that that only 20% were pain free using the Oxford Knee Score at 12 months (P.
Restricted postTKA knee extension (decreased or poor extension range) has been significantly correlated with decreases in the Oxford Knee Score and clinical outcomes related to standing, as indicated by the Short Form-36 physical component score [2].
She attained full range of knee motion by the end of three months with a satisfactory Oxford knee score of 42 (Figure 3).
Data was collected using a semi-structured questionnaire, Oxford Knee Score, and Short Form 12 Questionnaire.
The Knee Society Score (KSS), the functional KSS [24], the Western Ontario and McMaster Osteoarthritis Index (WOMAC) [25], and the Oxford Knee Score [26] were used for clinical assessment.
Pinedo-Villanueva and his study coauthors found 117,844 had data on pre- and postoperative knee pain assessed using the Oxford Knee Score (OKS) and quality of life measured with the EQ-5D instrument.
