Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients with a diagnosis of hip osteoarthitis requiring total hip arthroplasty and who do not have exclusion criteria will be offered participation in the trial, with the uncertainty regarding the best approach outlined. Consenting patients will be randomised to either the lateral or posterior approach on the day of operation. The patient will remain blinded; the surgical team will perform the lateral or posterior approach based on the contents of a sealed envelope.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Chronologically
Masking / blinding
