Primary outcome measure(s)
Functional patient-reported outcome — 5 years post-op The Oxford Knee Score (OKS) is a reliable 12-item, patient-reported questionnaire originally developed and validated specifically to assess function and pain in patients undergoing total knee replacement. It is short, reproducible, valid and sensitive to clinically important changes over time. Each of the 12 questions on the OKS is scored in the same way with the score decreasing as the reported symptoms increase (i.e. become worse). All questions are laid out with response categories denoting least (or no) symptoms to the left of the page (scoring 4) and those representing greatest severity lying on the right hand side (scoring 0), as detailed for question 1 below. This method, when summed, produces overall scores running from 0 to 48 with 48 being the best outcome.
