The HELLO Trial

The HELLO Trial
- An observational study to evaluate the health outcomes from a Mako robotic arm-assisted total hip replacement.
- The HELLO study assessed clinical outcomes in the 12 months following surgery for 200 patients undergoing a robotic arm-assisted total hip replacement. This was measured using patient reported outcome measures, surgery-related resource use and complications, physical activity monitoring, gait analysis and muscle strength testing.
- Recruitment and follow-up completed, currently in analysis.
