Primary outcome measure(s)
Oxford Knee Score (OKS) — 4-, 8-, 12-weeks and 1-year post-surgery Repeated mean score of a short questionnaire consisting of 12 questions ranging from 0 to 48 points, designed to assess function and pain after knee replacement surgery. Higher values represent a better outcome.
