Description of intervention(s) / exposure
Candidates in the study will be selected from a pool of patients undergoing total hip replacement using computer assisted surgery as standard of care. Additional observations will be made during the procedure resulting in the standard operating time (typically 1-2 hours) being extended by approximately 10 minutes. Patients will only be observed during the joint replacement surgery with no post-operative follow-ups included. The total duration of this observation study will be 12 months including patient recruitment.

Summary
Brief summary
This is an observational study to assess the clinical utility of new methods of displaying information collected during computer-assisted primary total hip replacement surgery used to treat patients with osteoarthritis. The position of the leg will be displayed, measured and recorded at various stages in the procedure. This information will be used to decide upon future improvements in software with the aim of providing surgeons with better guidance on the optimal position of hip replacement components.
