What this trial studies

This observational study aims to estimate VO2 max levels in patients before and after robotic arm-assisted hip arthroplasty surgery. It utilizes a non-exercise-based method, the Seismofit® System, which measures vibrations from heartbeats to provide VO2 max estimations, making it suitable for elderly patients with hip osteoarthritis. The study will also evaluate recovery through patient-reported outcomes and objective assessments, alongside monitoring physical activity and sleep patterns using wrist activity monitors for 12 weeks post-surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled for total hip replacement at Nuffield Hospital.

Not a fit: Patients requiring revision hip arthroplasty or those with implanted electronic devices may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer and more accessible way to assess fitness levels in patients undergoing hip surgery, potentially improving recovery outcomes.

How similar studies have performed: While the use of non-exercise methods for estimating VO2 max is less common, similar approaches have shown promise in other populations, suggesting potential for success in this context.
