Oxford Knee Score (OKS): Assessing Pain and Function
The Oxford Knee Score helps patients rate their knee pain and ability to perform daily tasks. Doctors use this short survey to track progress before and after knee replacement surgery.

Oxford Knee Score (OKS)
Designed to assess knee osteoarthritis, the Oxford Knee Score (OKS) is a 12-item questionnaire measuring pain and daily function. It's commonly used to evaluate results following total knee replacement surgery. This patient-reported tool helps clinicians track recovery progress and determine treatment success.

What is Oxford Knee Score (OKS)
The Oxford Knee Score (OKS) is a trusted tool for checking knee health. It helps doctors track recovery after joint replacement surgery. This short questionnaire features twelve simple questions covering key parts of daily life. It looks closely at both the pain you feel and how well your knee actually works. Patients rate difficulties with specific tasks like walking, washing, or climbing stairs. Each answer gets a score from zero to four, where a total of forty-eight means the joint is working perfectly. It captures the real impact of arthritis on your routine. Doctors use the results to see if surgery helped or if more treatment is needed. It’s quick to fill out in a waiting room or at home, making it easy to spot changes over time. By focusing on the patient's view, it ensures treatment plans match what people really need for a better quality of life.
The Oxford Knee Score can be scored using two main approaches: the original method and the modified system. 1. Original Method: In this older version, patients rate 12 questions from 1 to 5. You sum these up for a total between 12 (best outcome) and 60 (worst outcome). 2. Modified System: Most Aussie clinicians prefer this updated scale. Items are scored 0 to 4, where 4 represents the best status. The total ranges from 0 (severe symptoms) to 48 (excellent joint function). This metric helps track post op progress effectively.
