The aim of the proposed study is to perform a comparative pilot, randomized controlled trial of hip arthroscopy versus definitive total hip replacement (THR) for the treatment of early hip osteoarthritis (Tnnis Grade 1-2) in patients between the ages of 40-60 years.


The purpose of this pilot study is to determine study feasibility. Specifically, the investigators aim to:

  1. estimate the proportion of eligible patients providing consent,
  2. estimate the magnitude of the between-groups difference in the primary outcome (Hip Dysfunction and Osteoarthritis Outcome Score - HOOS) to aid in sample size calculation for the full study,
  3. estimate the compliance in completing the proposed outcome measures to determine the burden of questionnaire completion.
