What does your Oxford Knee Score mean?
The Oxford Knee Score is a reliable patient-reported outcome measure (PROM) designed to assess your knee function and pain. A score is calculated out of 48 based on your symptoms over the past 4 weeks. High scores indicate mild symptoms, while low scores suggest more significant mobility problems and daily living interference.
When should you speak to a clinician?
If knee osteoarthritis, an injury, or undiagnosed knee pain is making simple actions like walking, stairs, or kneeling difficult, you do not have to put up with it. You should consider speaking to a GP or physiotherapist if the pain affects your quality of life, limits mobility, or disturbs your sleep. Depending on your score and an orthopaedic assessment, your clinician may recommend physiotherapy, joint injections, or a total knee replacement (knee arthroplasty).
