A Comparison of Impingement Free Range of Motion With CT Scan After Manual and Robotic Total Hip Replacement

A Comparison of Impingement Free Range of Motion With CT Scan After Manual and Robotic Total Hip Replacement

Single-blinded randomised controlled trial comparing impingement with CT scan for manual and robotic total hip replacement. A pilot study of 50 participants.

This will be a two-arm, single blind (assessor blind), randomised controlled group study. It will take place in the NHS hospital setting. Stratification will be performed for age and sex by means of a minimisation technique during randomisation for each subject entering the trial.

Arm 1: Manual total hip replacement with conventional templating Arm 2: Robotic total hip replacement In the study 25 participants will receive manual THR with conventional templating; the other 25 will receive Robotic THR.

Following recruitment in outpatient clinics, participants will undergo baseline assessments, including imaging and clinical assessment. All participants will then undergo THR surgery, which will likely entail an inpatient hospital stay of 1-2 days. Post-operative rehabilitation will be in line with the normal standard care for all participants. Post-operatively participants will make two visits to clinic at 6 weeks and 12 months (standard of care).
