    Time frame: From Day 0 to 12 months

Other outcomes

  1. NRS pain intensity

    Numerical rating scale (NRS); 11-point scale ranges from '0' representing "no pain" to '10' representing "worst imaginable pain"

    Time frame: From Day 1 to 3 months

  2. Duration of need for walking aids

    Time frame: From Day 1 to 3 months

  3. Proportion of subjects using concomitant analgesics at any timepoint

    Time frame: From Day 1 to 3 months
