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.

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.
