  1. BMI= body mass index; ADL = Activities of daily living; HOOS = Hip disability and Osteoarthritis Outcome Score; KOOS = Knee disability and Osteoarthritis Outcome Score; THA = total hip arthroplasty TKA = total knee arthroplasty; MCS = Mental Component Summary scale of the Short Form-12
  2. Scenarios are based on the 25th, 50th and 75th percentile of the HOOS/KOOS score 6 months after surgery
