Clinical Trial Summary

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

Description:

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).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Impingement analysis by a CT guided software in all participants to enable a comparison of post-operative impingement between robotic THR and manual THR	To compare efficacy of Robotic THR in reducing post-operative impingement with Standard Manual THR	6 weeks post-intervention
Secondary	Using the Forgotten Joint Score (FJS-12) to determine improvement in Patient reported outcome measures	To determine whether the Robotic THR improves patient reported outcome measures	12 months
Secondary	Using the Oxford Hip score to determine improvement in Patient reported outcome measures	To determine whether the Robotic THR improves patient reported outcome measures	12 months
Secondary	Using the EuroQol 5-D (EQ5-D) to determine improvement in Patient reported outcome measures	To determine whether the Robotic THR improves patient reported outcome measures	12 months
Secondary	Measure leg length following surgery to determine whether robotic THR or manual THR is more effective at reducing leg length discrepancy.	To determine whether Robotic Surgery reduces leg length Discrepancy compared to manual THR	12 months
Secondary	Measure the duration of surgery and compare the duration of robotic THR to manual THR	To determine whether the Robotic THR increases operation duration compared to Manual surgery	During Surgery
Secondary	Measure and compare the length of stay between Robotic and Manual THR surgeries	To determine if length of hospital stay is reduced after robotic THR .	During length of stay in hospital average 3 days
