Permission to use and reproduce the Oxford Knee Score (OKS) has been granted by Oxford University Innovation’s Clinical Outcomes team. You can visit their website for more information about the measure or how to obtain a copyright licence: Clinical Outcomes Measures - Oxford University Innovation”.

We have built a tool that helps healthcare teams use patient-reported outcomes to assess function and pain after total knee replacement (TKR) surgery (arthroplasty).
